FSMA
Mathematics Curriculum
This system in which a child is constantly moving objects with his hands and actively exercising his senses, also takes into account a
child's special aptitude for mathematics. When they leave the material, the children very easily reach the point where they wish to
write out the operation. They thus carry out an abstract mental operation and acquire a kind of natural and spontaneous inclination
for mental calculations. ~The Discovery of the Child, Maria Montessori.
The mathematics curriculum is built around several research based curriculum and standards documents
including:
The National Common Core Standards
National Council of Teachers of Mathematics

Introduction to FSMA’s Mathematics Curriculum Framework In the Mathematics Curriculum, the teacher must be knowledgeable about the “Processes and Proficiencies” and have tools to
assess when students demonstrate these proficiencies as they work within the various mathematical strands. Teachers also need a
clear understanding of the knowledge goals for mathematical thinking within each of strands. The Montessori Mathematics
Curriculum Framework provides teachers with the goals for mathematics at each multi-age stage of development (5-7, 7-9, and 9-12
year olds). The Curriculum Framework provides the teacher with instructional strategies that are used in small group and individual
lessons/units using hands-on Montessori materials, TERC mathematics, and other resources to meet the individual instructional needs
of the child. These lessons provide opportunities for teachers to observe children and to evaluate their progress towards the goals for
learning across each strand of the mathematics curriculum as well as their understanding and demonstration of the processes and
proficiencies. The Framework provides various formative and summative assessment tools for teachers to confirm their observations,
and to make adjustments to instruction as a result of those observations. These tools include daily observations, teacher designed
assessments, and formal assessments from the TERC Curriculum. Finally, the Framework provides indicators of when a child is off-
track with their mathematical thinking.
The development of the child in Mathematics is embedded within the context of a classroom that supports the best educational
practices. It is generally accepted that the workforce of the future will require skills such as creative and innovative thinking, comfort
with ideas and abstraction, along with a global worldview and vibrant imagination. Research (Adams, 2005) shows that children
develop these skills in classrooms designed to promote intrinsic motivation; to provide choice, time for focus and deep study in areas
of interest; to allow opportunities to experiment and discover, and to develop a focus on “What did you learn?” rather than “How well
did you do?” The overall Montessori Program is designed to support the following:
A focus on big ideas and essential questions with extended work periods to allow for depth of understanding and habits of
mind.
Child-centered inclusive learning environments that utilize differentiated instruction and flexible grouping to meet
individual children’s learning needs.
Classroom-based assessment and observation that informs instructional decision making.
Hands-on interactive curricular materials and classroom environment supporting children developing from concrete to
abstract thinking.
Academic development supported by an emphasis on the social/emotional development of the child within a multi-age
community of learners.
Collaborative learning and community service leading to mutual respect of others and the development of the child’s global
perspective.

Curriculum Resources and Materials
There are three resources that will be the foundation for the math curriculum at FSMA. (Each is described below)
Montessori Math Lessons
TERC Math
Connected Mathematics
Montessori Math Lessons are a part of a larger integrated curriculum. This integrated curriculum is founded on the teaching of
five “Great Lessons.” Relevant to the Math Curriculum articulated in this document is the fifth Great Lesson, “The History of
Mathematics,” also called “The Story of Numbers,” which focuses on learning about the numeric system of early civilizations and
continuing by looking at the different number systems that have been uses and culminates with a study of the decimal system used
today.
The Fifth Great Lesson: The Story Of Numbers leads to the study of:
Mathematics: operations, fractions, decimals, multiples, squares, cubes, percentages, ration, probability, intro to algebra
Numbers: origins of numbers and systems, bases, types of numbers, scientific notation, mathematicians
Geometry: congruency, similarity, nomenclature of lines, angles, shapes, solids, measurement, and theorems
Application: story problems, measurement, estimation, graphs, patterning, rounding, money concepts
Montessori Math in the Lower Elementary Classroom: The lower elementary Montessori classroom is full of ongoing discoveries.
Spurred on by the telling of the fifth Great Lesson, “The Story of Numbers,” children are motivated to learn about their own number
system and uncover the mysteries as did those who came before. The absorbent mind of early childhood has given way to a reasoning
mind which enjoys learning about natural truths and laws of nature. The mathematical facts learned in the younger grades are now
tested to see if there are rules and laws to be discovered and manipulated. Patterns are sought as the child seeks to discover the
empirical truths of the universe through the use of the concrete Montessori math materials. It is now that children are able to use their
imaginations to see beyond the immediate. They are able to see beyond the concrete representations and imagine higher place values
within the decimal system.
Montessori Math in the Upper Elementary Classroom: The inquisitiveness of the upper elementary Montessori student is astounding.
The beauty of the advanced squaring and cubing materials beckons like beacons, inviting the students to come explore and learn with
5
them. They dive into the study of fractions and decimals, eager to move beyond to more complex mathematics, geometry, and algebra.
While the concrete materials are still in place, the need for repetition is gone. “Show me. Then, show me more” is the litany of the
upper elementary Montessori math students. Upper elementary students move quickly from the concrete experience to abstract
thought. They are eager to test their knowledge with pencil and paper and need, at times, a gentle reminder to return to the materials as
a way of building neurological pathways.
TERC Math (K-5th
grade) helps students develop a strong conceptual foundation and skills based on that foundation. Each
curriculum unit focuses on an area of content and provides opportunities for students to develop and practice ideas across a variety of
activities and contexts that build on each other. The units also address the learning needs of real students in a wide range of classrooms
and communities. There are six major goals of the TERC Curriculum:
Support students to make sense of mathematics and learn that they can be mathematical thinkers
Focus on computational fluency with whole numbers as a major goal of the elementary grades
Provide substantive work in important areas of mathematics—rational numbers, geometry, measurement, data, and
early algebra—and connections among them
Emphasize reasoning about mathematical ideas
Communicate mathematics content and pedagogy to teachers
Engage the range of learners in understanding mathematics.
Underlying these goals are three guiding principles that are our touchstones as we approach both students and teachers as agents of
their own learning:
1. Students have mathematical ideas. The curriculum must support all students in developing and expanding those ideas.
2. Teachers are engaged in ongoing learning about mathematics content and about how students learn mathematics. The
curriculum must support teachers in this learning.
3. Teachers collaborate with the students and curriculum materials to create the curriculum as enacted in the classroom. The
curriculum must support teachers in implementing the curriculum in a way that accommodates the needs of their particular
students.
Connected Math (6th
grade) is a mathematics curriculum designed for students in grades 6–8. Each grade level of the
curriculum is a full-year program and covers numbers, algebra, geometry/measurement, probability, and statistics. The curriculum
uses an investigative approach, and students utilize interactive problems and everyday situations to learn math concepts.
6
Mathematics Processes and Proficiencies
3. Construct viable arguments and
critique the reasoning of others.
Mathematically proficient students:
Understand and use stated assumptions,
definitions, and previously established
results in constructing arguments.
Make conjectures and build a logical
progression of statements to explore
the truth of their conjectures.
Analyze situations by breaking them into
cases.
Recognize and use counterexamples.
Justify their conclusions, communicate
them to others, and respond to the
arguments of others.
Make plausible arguments that take into
account the context from which the
data arose, reasoning inductively.
Compare the effectiveness of two
plausible arguments.
Distinguish correct logic or reasoning
from that which is flawed, and, f there
is a flaw in an argument, explain what
it is.
Listen to or read the arguments of others,
decide whether they make sense.
Ask useful questions to clarify or improve
arguments.
Construct arguments using concrete
referents such as objects, drawings,
diagrams, and actions. Such
arguments can make sense and be
correct, even though they are not
generalized or made formal until later
grades. (younger students)
Determine domains to which an argument
applies. (older students)
4. Model with mathematics.
Mathematically proficient students:
Apply the mathematics they know to
solve problems arising in everyday
life, society, and the workplace.
In early grades, this might be as simple
as writing an addition equation to
describe a situation.
In middle grades, a student might apply
proportional reasoning to plan a
school event or analyze a problem
in the community.
In high school, a student might use
geometry to solve a design problem
or use a function to describe how
one quantity of interest depends on
another.
Apply what they know.
Make assumptions and approximations
to simplify a complicated situation,
realizing that these may need
revision later.
Identify important quantities in a
practical situation.
Map relationships using such tools as
diagrams, two-way tables, graphs,
flowcharts and formulas.
Analyze relationships mathematically
to draw conclusions.
Interpret their mathematical results in
the context of the situation.
Reflect on whether the results make
sense, possibly improving the
model if it has not served its
purpose.
1. Make sense of problems and
persevere in solving them.
Mathematically proficient students:
Explain to themselves the meaning of a
problem.
Look for entry points to its solution.
Analyze givens, constraints,
relationships, and goals.
Make conjectures about the form and
meaning of the solution.
Plan a solution pathway rather than
simply jumping into a solution attempt.
Consider analogous problems, and try
special cases and simpler forms of the
original problem in order to gain
insight into its solution.
Monitor and evaluate their progress and
change course if necessary.
Explain correspondences between
equations, verbal descriptions, tables,
and graphs or draw diagrams of
important features and relationships,
graph data.
Search for regularity or trends.
Check their answers to problems using
a different method.
Ask themselves, “Does this make
sense?”
Understand the approaches of others to
solving complex problems.
Identify correspondences between
different approaches.
Use concrete objects or pictures to help
conceptualize and solve a problem.
(younger students)
Transform algebraic expressions or
change the viewing window on their
graphing calculator to get the information they need, depending on the context of the
problem. (older students)
2. Reason abstractly and
quantitatively.
Mathematically proficient students:
Make sense of quantities and their
relationships in problem
situations.
Bring two complementary abilities to
bear on problems involving
quantitative relationships:
The ability to decontextualize, to
abstract a given situation and
represent it symbolically and
manipulate the representing
symbols as if they have a life of
their own, without necessarily
attending to their referents
The ability to contextualize, to pause
as needed during the
manipulation process in order to
probe into the referents for the
symbols involved.
Create a coherent representation of
the problem at hand, considering
the units involved.
Attend to the meaning of quantities,
not just how to compute them.
Know and flexibly use different
properties of operations and
objects.

Mathematics Processes and Proficiencies
5. Use Appropriate Tools Strategically.
Mathematically proficient students:
Consider the available tools when solving a
mathematical problem. These tools
might include pencil and paper,
concrete models, a ruler, a protractor, a
calculator, a spreadsheet, a computer
algebra system, a statistical package,
or dynamic geometry software.
Develop familiarity with tools appropriate
for their grade or course to make sound
decisions about when each of these
tools might be helpful, recognizing
both the insight to be gained and their
limitations. For example,
mathematically proficient high school
students analyze graphs of functions
and solutions generated using a
graphing calculator.
Detect possible errors by strategically using
estimation and other mathematical
knowledge.
Know that technology can enable them to
visualize the results of varying
assumptions, explore consequences,
and compare predictions with data.
Identify relevant external mathematical
resources, such as digital content
located on a website, and use them to
pose or solve problems.
Use technological tools to explore and
deepen their understanding of
concepts.
6. Attend to precision.
Mathematically proficient students:
Communicate precisely to others.
Use clear definitions in discussion
with others and in their own
reasoning.
State the meaning of the symbols they
choose, including using the equal
sign consistently and
appropriately.
Use care to correctly specify units of
measure, and label axes to clarify
the correspondence with
quantities in a problem.
Calculate accurately and efficiently.
Express numerical answers with a
degree of precision appropriate
for the problem context.
Give carefully formulated
explanations to each other.
(elementary school)
Examine claims and make explicit use
of definitions. (high school)
7. Look for and make use of structure.
Mathematically proficient students:
Look closely to discern a pattern or
structure.
Young students might notice that three and
seven more is the same amount as
seven and three more, or they may sort
a collection of shapes according to
how many sides the shapes have.
Later, students will see 7 × 8 equals the
well-remembered 7 × 5 + 7 × 3, in
preparation for learning about the
distributive property.
Older students can look at the expression
2x + 9x + 14 and see the 14 as 2 × 7
and the 9 as 2 + 7.
Recognize the significance of an existing
line in a geometric figure and can use
the strategy of drawing an auxiliary
line for solving problems.
Consider an overview and be able to shift
perspective.
See complicated things as single objects or
as being composed of several objects.
For example, they can see 5 – 3(x – y)2 as 5
minus a positive number times a
square and use that to realize that its
value cannot be more than 5 for any
real numbers x and y.
8. Look for and express regularity in
repeated reasoning.
Mathematically proficient students:
Notice if calculations are repeated, and
look both for general methods and for
shortcuts.
Upper elementary students might notice
when dividing 25 by 11 that they are
repeating the same calculations over
and over again, and conclude they
have a repeating decimal.
Middle school students might pay
attention while calculating slope as
they repeatedly check whether points
are on the line through (1, 2) with
slope 3, and abstract the equation (y –
2)/(x – 1) = 3.
High school students might notice the
regularity in the way terms cancel
when expanding (x – 1)(x + 1), (x –
1)(x2 + x + 1), and (x – 1)(x
3 + x
2 + x +
1), leading them to the general
formula for the sum of a geometric
series.
Apply what they know.
Maintain oversight of the problem solving
process, while attending to the details.
Evaluate the reasonableness of their
intermediate results.

Unit Overviews of TERC Kindergarten Curriculum
(From TERC 2nd
edition overview materials) Number and Operations: Whole Numbers: Students develop strategies for accurately counting quantities to 10
and beyond. They have opportunities to count and create sets (objects, people, drawings, etc.), to count aloud, and
to write and interpret numerals in a variety of contexts. They develop visual images for quantities and a sense of
the relationship between them (10 is more than 5; 4is less than 6; each counting number is 1 more, etc.). The count-
ing work serves as a bridge to the operations of addition and subtraction. Students have repeated experiences join-
ing two or more amounts, removing an amount from a whole, and decomposing a number into two or more parts.
Measurement: Students are introduced to length as a dimension, and use direct comparison to compare the
lengths of objects. Throughout, there is a focus on language for describing and comparing lengths. Later, students
use multiple nonstandard units (e.g. cubes, craft sticks) to quantify length, and consider whether particular
measurement strategies (e.g. different start and end points, units laid out in a crooked line or in a line with gaps
and/or overlaps between units) result in accurate measurements.
Patterns and Functions: Students sort related objects into groups and identify attributes, as they begin their work
with patterns. They consider which attribute (ex. color or shape) is important as they construct, describe, and
extend various patterns, determine what comes next in a repeating pattern, and think about how two patterns are
similar and different. Students also analyze the structure of a repeating pattern by identifying the unit of the pattern.
Geometry: As they identify 2-D and 3-D shapes in their environment, students describe and compare shapes.
They discuss characteristics such as size, shape, function, and attributes such as the number of sides or faces.
Students construct 2-D and 3-D shapes, and combine shapes to make other shapes. The optional Shapes software
extends and deepens the 2-D geometry work.
Data Analysis: Students sort objects according to their attributes and organize data (i.e. favorite lunch foods) into
different categories. As students collect data about themselves, they develop strategies for keeping track of who has
responded to a survey, and for recording and representing data. Students begin to understand the processes
involved in data analysis by choosing and posing a question, determining how to record responses, and counting
and making sense of the results.

Unit Overviews of TERC 1st Grade Curriculum
(From TERC 2nd
edition overview materials)
Number and Operations: Whole Numbers Students have repeated practice with the counting sequence, develop strategies for
accurately counting a set of up to 50 objects by ones, and begin to count by groups in meaningful ways. Much of the work focuses on
addition and subtraction, and on developing an understanding of these operations. Students solve story problems, compose and
decompose quantities in different ways, and add and subtract single-digit numbers. By the end of the year, students are expected to
count on to combine two small quantities; to subtract one small quantity from another; and to be fluent with the two-addend
combinations of 10.
Geometry Students identify, describe, draw, and compare 2-D and 3-D shapes. The 2-D work is particularly focused on identifying
and describing triangles, while the 3-D work asks students to pay particular attention to identifying a shape’s faces and corners.
Students also explore the relationship between 2-D and 3-D shapes as they match 2-D representations to 3-D shapes or structures.
Data Analysis Students sort related objects according to a particular attribute and describe what distinguishes one group from another.
They are introduced to, discuss, and compare standard forms of representation including picture graphs, tallies, charts, and bar graphs.
They carry out their own data investigation, developing a question and then collecting, representing, describing and interpreting the
data.
Measurement Students develop a foundation of skills for accurate linear measurement. They measure both objects and distances,
explore what happens when something is measured with different sized units, and learn that when something is measured twice with
the same unit, the same results should be obtained.
Patterns and Functions Students create, describe, extend, and make predictions about repeating patterns and analyze their structure
by identifying the unit. Students also work with number sequences associated with repeating patterns, and consider situations that have
a constant increase.

*Information collected from these assessments will be used to create individual learning paths for students in the
Number Sense/ Numeration Unit.
Ongoing Formal and Informal Assessments: (adapted information from TERC 2nd
edition Guidelines) Observing the Students: In each unit, bulleted lists of questions that suggest what teachers might focus on as they observe students
and look at their written work for particular activities are included. They also offer ideas about what's important about the activity, and
what math ideas children are likely to struggle with.
Formative Assessment/ Teacher Checkpoints: In each unit, there is a suggested time to 'check in,' to pause in the teaching sequence
and get a sense of how both the class as a whole and individual students in your class are doing with the mathematics at hand. They
usually come earlier in a unit, and are meant to give a sense of how your class is doing, and how you might want to adapt the pacing of
the rest of the unit.
Summative Assessment Activities: Assessment activities are embedded in each unit to help examine specific pieces of student work,
figure out what it means, and provide feedback. These often come towards the end of a unit and are meant to offer a picture of how
students have mastered the mathematics of the unit at hand. Each is a learning experience in and of itself, as well as an opportunity to
gather evidence about students' mathematical understandings. These activities often have Teacher Notes associated with them that
discuss the problem, provide support in analyzing student work and responses, and offer guidance about next steps for the range of
students in a class.
Portfolios/Choosing Student Work to Save: At the end of the last investigation of each unit, there are suggestions for choosing
student work to save to develop a portfolio of a student's work over time.

Unit Summary: Number Sense and Numeration – (information adapted from TERC 2nd
Edition Guidelines)
A main focus in Kindergarten is counting, which is the basis for understanding the number system and for almost all the number
work in the primary grades. Students hear and use the counting sequence (the number names, in order) in a variety of contexts. They
have many opportunities to connect the number names with the written numbers and with the quantities they represent. They have
repeated experiences counting sets of objects, and matching and making sets of a given size. As students count sets of objects and
make equal sets they begin to see the importance of counting each object once and only once, and of having a system for keeping track
of what has been counted and what still remains to be counted. Students engage in repeated practice with counting and develop visual
images for quantities to 10. As students are developing accurate counting strategies they are also building an understanding of how
the numbers in the counting sequence are related: Each number is one more (or one less) than the number before (or after) it. Students
develop an understanding of the concepts of greater than, fewer than, and equal to, and develop language for describing quantitative
comparisons (e.g. bigger, more, smaller, fewer, less, same, equal) as they count and compare quantities.
Enduring Understandings:
• Developing strategies for accurately counting a set of objects
by ones
• Developing an understanding of the magnitude and position
of numbers
Students will be able to:
• Count a set of up to 10 objects
• Compare two quantities up to 10 to see which is greater
• Count a set of up to 15 objects
• Figure out what is one more or one fewer than a number
• Write the numbers up to 10
• Count a set of up to 20 objects
Throughout first grade, students work on developing strategies for accurately counting a group of up to 50 objects. They have
repeated practice with the counting sequence, both forwards and backward, and with counting and keeping track of sets of objects.
They also connect the number names with the written numbers and the quantities that they represent. As students are developing
accurate counting strategies they are also building an understanding of how the numbers in the counting sequence are related—each
number is one more (or one less) than the number before (or after) it. As students build this understanding, they compare and order
quantities and develop a sense of the relative size of numbers and the quantities they represent. Students also make sense of counting
by numbers other than 1. They connect the number sequence of counting by 2s, 5s, and 10s to the quantities they represent. As they
work on activities that involve multiple groups of the same amount, they build an understanding that as they say each number in the
counting sequence, they are adding 2, 5 or 10 more things. This leads to more efficient and accurate counting.

Unit Summary: Operations and Algebra– (information adapted from TERC 2nd
Edition Guidelines)
Over the course of the year, Kindergarten students encounter a number of general ideas as they count and begin their work on
addition and subtraction. For example, students develop ideas about how numbers describe the size of a set and that the number of
objects in a set is fixed no matter how it is arranged and counted, and different sets may have the same number of objects. As
kindergarteners repeatedly count a set made up of things in two different colors (e.g., a set of 8 rods; 5 of them red and 3 of them
yellow), they begin to make the following generalization:
Enduring Understandings:
• When counting a set of objects, it does not matter in what order one counts them; the result is the same no matter how many objects
are in the set.
• When adding (the counting numbers starting with 1), the sum is greater than any of the addends. When subtracting, the difference is
less than the amount from which you’re subtracting.
Throughout the course of Grade 1, students encounter a number of general ideas as they work with counting, numbers, and
operations. . These activities should lead to a beginning understanding of what in later years they will call the commutative property
of addition. (• Two numbers added in either order yield the same sum: 2 + 7 = 7 + 2)
. Students also encounter the inverse relationship between addition and subtraction as they work on related story problems.
For example: Vic and Libby were in charge of collecting pencils during cleanup time. Vic found 7 pencils and Libby found 3. How
many pencils did they collect? Libby and Vic put the 10 pencils in a pencil basket. Then Diego came by and took 3 of them for the kids
at his table. How many pencils were left in the basket? In the first problem, 7 and 3 are joined to make 10; in the second, 3 is removed
from 10, leaving 7. Students are asked, Does the first problem help solve the second? As students do the important work of examining
the relationship between these two problems, some students may say, “Seven and three come together to make 10. If 3 goes away, 7 is
left and that’s the answer.”
Enduring Understandings:
• Addition and subtraction are related. If adding two numbers gives a certain sum, then subtracting one of the addends from the sum
results in the other addend: 7 + 3 = 10; 10 – 7 = 3; 10 – 3 = 7
Students will be able to:
apply the commutative property and their understanding of the inverse relationship between addition and subtraction, as they
develop strategies for solving addition and subtraction problems.
apply the inverse relationship between addition and subtraction and their understanding that the same number can be
decomposed in different ways when they create equivalent expressions in order to solve a problem (e.g., 6 + 4 = 5 + 5 and 8 +
5 = 10 + 3) or when they use addition combinations they know to solve more difficult problems (e.g., since 5 + 5 = 10, 5 + 6
must equal 10 + 1, or 11).
20
Other generalizations highlighted in first grade include:
• If one number is greater than another, and the same number is added to each, the first sum will be larger than the second: 3 + 5 > 2 +
5
• If 1 is added to an addend, the sum increases by 1. Or more generally, if any number is added to (or subtracted from) an addend, the
sum increases (or decreases) by that number: 5 + 5 = 10, so 5 + 6 = 11; 5 + 5 = 10, so 5 + 4 = 9
• If an amount is added to one addend and subtracted from another addend, the sum remains the same: 6 + 6 = 12; 7 + 5 = 12
• Subtraction “undoes” addition, as in 22 + 8 – 8 = 22.
• Any missing addend problem can be solved by subtraction. Conversely, any subtraction problem can be solved as a missing addend:
• 10 + 6 = 16; 16 – 6 = 10 or 16 – 10 = 6

Unit Summary: Patterns– (information adapted from TERC 2nd
Edition Guidelines)
Kindergarten students construct, describe, extend, and determine what comes next in repeating patterns. To identify and construct
repeating patterns, students must be able to identify the attributes of the objects in the pattern. Therefore students first work on sorting
objects by their attributes, before they begin constructing their own patterns. Students encounter patterns with two (AB, AAB, ABB)
or three (ABC) elements. As students construct and describe many different patterns, they become more familiar with the structure of
patterns, are able to identify what comes next in a pattern, and can begin to think about how two patterns are similar and different.
After having many opportunities to construct their own patterns and extend patterns made by others, students begin to analyze the
structure of a repeating pattern by identifying the unit of the pattern—the part of the pattern that repeats over and over.
Enduring Understanding:
• Objects can be sorted and classified
• Constructing, describing, and extending repeating patterns
• Identifying the unit of a repeating pattern
Students will be able to:
• Copy, construct, and extend simple patterns, such as AB and
ABC
• Begin to identify the unit of a repeating pattern
In first grade, creating, describing, extending, and making predictions about repeating patterns is the focus. By building or acting out
these patterns and thinking through how the pattern continues, students analyze the regularities of the pattern to determine what comes
next or what will come several steps ahead in the pattern. Students analyze the structure of a repeating pattern by identifying the unit
—the part of the pattern that repeats over and over. By focusing on the unit of the repeating pattern, students shift their focus from
seeing that “red follows yellow and yellow follows red” to how the repeating pattern is constructed of an iterated red-yellow unit. This
focus allows students to analyze more complex patterns. Students also compare patterns and begin to notice how patterns are the same.
For example, a red, yellow, red, yellow pattern and a green, blue, green, blue pattern have the same structure. Students then work with
number sequences associated with repeating patterns. Associating the counting numbers with this pattern allows new kinds of
questions about the pattern, such as the following: “What color will the 17th square be?” “Is the 20th square black?” Numbering the
elements of a repeating pattern provides another way to describe that pattern. Comparison across contexts helps students focus on how
the same start number and the same amount of constant increase can create the same number sequence in different situations.
Enduring Understanding:
• Constructing, describing, and extending repeating patterns
• Identifying the unit of a repeating pattern
• Constructing, describing, and extending number sequences
with constant increments generated
by various contexts
Students will be able to:
• Construct, describe, and extend a repeating pattern with the

• Identify the unit of a repeating pattern for patterns with the
structure AB or ABC
• Describe how various AB or ABC patterns are alike?•
Determine what comes several steps beyond the visible part of
an AB, ABC, AAB, or ABB repeating pattern
• Construct, extend, and describe a pattern that has a constant
increase for the sequences 1, 3, 5, …; 2, 4, 6, …; 1, 4, 7, …; 2,
5, 8, …; and 3, 6, 9, … through counting and building

Unit Summary: Measurement and Data– (information adapted from TERC 2nd
Edition Guidelines)
In Kindergarten, students are introduced to length and linear measurement through measuring by direct comparison. As they
compare objects to determine the longest object, they discuss and make sense of important aspects of accurate measurement such as
choosing which dimension to measure. Students begin to think about the different dimensions of objects. They also become
comfortable with, and use language to describe length—long, short, wide, tall, high (and the comparative forms –longer, wider, etc).
Enduring Understanding:
Linear Measurement - Understanding length and using linear
units
Students will be able to:
• Decide which of two objects is longer
• Measure the length of an object by lining up multiple units
In grade 1, it is important for students to develop a sense of how measurement is used--and when it is helpful—in the real world. The
focus is on developing a foundation of skills for accurate linear measurement, such as knowing where to start and stop measuring,
understanding how measuring tools must be lined up so that there are no gaps or overlaps, knowing which dimension to measure,
measuring the shortest line from point to point, and understanding that many measurements are not reported in whole numbers.
Regardless of what is measured, students learn that when one measures an object twice--or when two different people measure it--the
same results should be obtained, assuming the same measuring unit is used. Students also explore what happens when something is
measured with small units versus larger units. Students begin to see that measuring an object in cubes will result in a different count
than will measuring the same object in inch tiles or paper clips, but may not yet see the inverse relationship between size of unit and
number of units needed to cover a distance.
Enduring Understanding:
Linear Measurement -
• Understanding length
• Using linear units
• Measuring with standard units
Students will be able to:
• Demonstrate measuring techniques when measuring a
distance with nonstandard or standard units. These techniques
include starting at the beginning, ending at the end, leaving no
gaps or overlaps, measuring in a straight line, and keeping
track of the number of units
• Know at least one way of describing a measurement that falls
between two whole numbers
• Understand that the same results should be obtained when the
same object is measured twice, or when two different people
measure the same object (using the same unit)
*Understand that measuring with different-sized units will
result in different numbers

Unit Summary: Geometry– (information adapted from TERC 2nd
Edition Guidelines)
The geometry work in Kindergarten builds on students’ firsthand knowledge of shapes to further develop their spatial sense and
deepen their understanding of the two-and three-dimensional world in which they live. As students identify the different shapes that
make up the world, they are encouraged to use their own words to describe both 2-D and 3-D shapes. In this way, they form images of
familiar shapes through associating them with familiar objects. Students explore the geometric idea that shapes can be combined or
subdivided to make other shapes. For example, they investigate how 3-D shapes can be combined to form a particular rectangular
prism. By putting shapes together and taking shapes apart, students deepen their understanding of the attributes of shapes and how
shapes are related. Students also construct 2-D and 3-D shapes with clay and on Geoboards. As they construct shapes they form
mental images of the shapes and think about the attributes of particular shapes. Enduring Understanding:
• Composing and decomposing 2-D and 3-D shapes
• Describing, identifying, comparing, and sorting 2-D and 3-D
shapes
Students will be able to:
• Describe the overall size, shape, function, and/or features of
familiar 2-D and 3-D shapes
• Construct 2-D and 3-D shapes
• Make 2-D and 3-D shapes by combining shapes The emphasis of geometry work in 1st grade is on careful observation, description and comparison of two-dimensional (2-D) and three-
dimensional (3-D) geometric shapes. Students describe 2-D shapes, sort them and compare them, and they think about questions like the
following: What makes a triangle a triangle? How are triangles different from squares? Developing visual images of shapes as well as drawing 2-D
shapes are ways that students come to know the important features of shapes. When they sort 2-D shapes, they make groups of shapes that “go
together,” which requires them to look for similarities and differences among the attributes of different
shapes. Students look for 3-D shapes in their own environment and they work with 3-D shapes (whose faces are familiar 2-D shapes) such as
Geoblocks, manufactured boxes, and boxes made by students. Students also learn about geometric relationships by composing and decomposing
shapes. As they fill in the same shape outline with pattern blocks in different ways, they break apart or combine shapes in order to change how the
shape is filled. When using the geoblocks, students notice, for example, that two cubes can be put together to make a rectangular prism and that
two triangular prisms can be put together to make a cube. Students investigate the relationship between 3-D shapes and 2-D representations of
those shapes. By matching 3-D objects to outlines of their faces, to pictures, and to drawings of other students, they identify shapes by looking
carefully at some parts of the shape and then visualizing what the whole shape looks like. Moving back and forth between 3-D objects and their 2-
D representations helps students describe and compare the characteristics of common 3-D shapes.. Enduring Understanding:
Features of Shapes
• Composing and decomposing 2-D shapes
• Describing, identifying, and comparing 2-D and 3-D shapes

Unit Overviews of TERC 2nd
Grade Curriculum
(From TERC 2nd
edition overview materials) Number and Operations: Whole Numbers Students transition to thinking and working with groups, explore the composition of
numbers to 100, and develop an understanding of the base-10 structure of our number system. The bulk of the work focuses on or
supports the development of fluency with the operations of addition and subtraction. By the end of the year, students are expected to
be fluent with the addition combinations to 10+10; to add 2 two-digit numbers accurately and efficiently; and to subtract two-digit
numbers accurately.
Number and Operations: Fractions Students develop an understanding that fractions are equal parts of a whole, whether the whole
is a single object or a set of objects. They work with halves, thirds, and fourths, including fractions greater than one, and learn what
the numbers in fraction notation represent.
Geometry Students work with 2-D and 3-D shapes, with a particular focus on properties of rectangles and rectangular prisms. They
are introduced to rectangular arrays (e.g. 2 rows of 3 squares), use them to find the area of rectangles, and develop an understanding of
mirror symmetry.
.
Patterns and Functions Students use tables to represent and explore situations with constant ratios (e.g. if 6 triangles cover a
hexagon, how many triangles would cover 5 hexagons?). They also work with repeating patterns that provide an opportunity to think
about odd and even numbers and what happens when you count by 3’s starting at 1; starting at 2; starting at 3.
Data Analysis Students sort and classify objects and categorical data. They also work with numerical data, and see and use a variety
of data representations including Venn diagrams, cubes towers, line plots, and student-created representations. They complete two
data investigations and compare sets of data.
Measurement Students use direct comparison, indirect comparison, and linear units to measure and compare the lengths of different
objects. They use nonstandard (e.g. cubes) and standard (e.g. inches, feet, centimeters) units of measure. Students also measure time as
they practice naming, notating and telling time on digital and analog clocks. They use timelines to represent intervals of time and
calculate elapsed time.

Grade Curriculum
(From TERC 2nd
edition overview materials)
Number and Operations: Whole Numbers Students build an understanding of the base-ten number system to 1,000. Much of the
work focuses on or supports the development of fluency with the operations of addition and subtraction. Students investigate the
properties of multiplication and division, including the inverse relationship between these two operations, and develop strategies for
solving multiplication and division problems. By the end of the year, students are expected to solve three-digit addition problems
using at least one strategy accurately and efficiently; to solve subtraction problems with three-digit numbers; and to be fluent with the
multiplication combinations with products to 50.
Number and Operations: Fractions Students use fractions (halves, fourths, eighths, thirds, and sixths) and mixed numbers as they
solve sharing problems and build wholes from fractional parts. Students are introduced to decimal fractions (0.50 and 0.25), using the
context of money, and gain familiarity with fraction and decimal equivalents involving halves and fourths.
Geometry and Measurement Students study the attributes of 2-D and 3-D shapes and use these attributes to classify shapes. Students
determine the volume of the rectangular prisms that fit into a variety of open boxes. They measure length and perimeter with both U.S.
standard (inches, feet and yards) and metric (centimeters and meters) units. They find area, identify the internal angle of a rectangle or
square as 90 degrees, and use right angles as a benchmark as they consider the sizes of angles of other polygons.
Patterns and Functions Students study situations of change as they examine temperature over time in different places around the
world, analyze number sequences generated by repeating pattern.. They make, read, and compare tables and line graphs that
show a relationship between two variables in situations of change over time. They use both tables and graphs to examine and compare
situations with a constant rate of change.
Data Analysis Students collect, represent, describe, and interpret both categorical and numerical data. They consider how to look at a
data set as a whole and make statements about the whole group. By conducting their own data investigations, students consider how
the question they pose and the way they conduct their study impact the resulting data.

Ongoing Formal and Informal Assessments: (adapted information from TERC 2nd
edition Guidelines) Observing the Students: In each unit, bulleted lists of questions that suggest what teachers might focus on as they observe students
and look at their written work for particular activities are included. They also offer ideas about what's important about the activity, and
what math ideas children are likely to struggle with.
Formative Assessment/ Teacher Checkpoints: In each unit, there is a suggested time to 'check in,' to pause in the teaching sequence
and get a sense of how both the class as a whole and individual students in your class are doing with the mathematics at hand. They
usually come earlier in a unit, and are meant to give a sense of how your class is doing, and how you might want to adapt the pacing of
the rest of the unit.
Summative Assessment Activities: Assessment activities are embedded in each unit to help examine specific pieces of student work,
figure out what it means, and provide feedback. These often come towards the end of a unit and are meant to offer a picture of how
students have mastered the mathematics of the unit at hand. Each is a learning experience in and of itself, as well as an opportunity to
gather evidence about students' mathematical understandings. These activities often have Teacher Notes associated with them that
discuss the problem, provide support in analyzing student work and responses, and offer guidance about next steps for the range of
students in a class.
Portfolios/Choosing Student Work to Save: At the end of the last investigation of each unit, there are suggestions for choosing
student work to save to develop a portfolio of a student's work over time.

Unit Summary: Number Sense and Numeration– (information adapted from TERC 2nd
Edition Guidelines)
In grade 2, students have varied opportunities to count sets of objects by ones, write the number sequence, and explore and compare
representations of the counting numbers on the number line and the 100 chart. As the school year progresses, most second graders
shift from thinking and working primarily with ones to thinking and working with groups of ones. To help them make this shift,
students have many opportunities to develop strategies for grouping and for counting by groups. The focus is first on contexts that
encourage counting by groups of 2, 5, or 10 and then specifically on groups of 10 and the base ten structure of our number system.
Students work extensively with contexts and models that represent the place value structure of our base-ten number system. They use
these contexts to build and visualize how two-digit numbers are composed. For example, 33 cents can be composed of 3 dimes and 3
pennies or 2 dimes and 13 pennies or 1 dimes and 23 pennies. As an extention of their work with number composition, students
investigate even and odd numbers through the context of partners (groups of two) and teams (two equal groups) and then develop
definitions of even and odd numbers.
Enduring Understanding:
Counting and Quantity:
• Developing strategies for accurately counting a set of objects
by ones and groups
• Developing an understanding of the magnitude and sequence
of numbers up to 100
• Counting by equal groups
The Base Ten Number System
• Understanding the equivalence of one group and the discrete
units that comprise it
Students will be able to:
• Count a set of objects up to 60 in at least one way
• Define even and odd numbers in terms of groups of two or
two equal groups
• Recognize and identify coins and their values
• Interpret and solve problems about the number of tens and
ones in a quantity
• Know coin equivalencies for nickel, dime, and quarter
• Count by 2s, 5s, and 10s, up to a number
In Grade 3, students build an understanding of the base-ten number system to 1,000 by studying the structure of 1,000 and using a
base-ten context to represent the place value of two-digit and three-digit numbers. Students identify the hundreds digit as representing
how many 100s are in the number, the tens digit as representing how many 10s, and the ones digit as representing how many 1s. They
also break numbers into 100s, 10s, and 1s in different ways. their work with number and operations in Grade 3, students focus
particularly on addition and subtraction. Students solve addition and subtraction problems with two-digit and three-digit numbers,
developing computation strategies that are built on adding and subtracting multiples of 10 and finding combinations that add to 100.
Addition strategies include breaking the numbers apart and then either adding by place or adding on one number in parts. They also
examine problems that lend themselves to changing the numbers in order to make them easier to add. Subtraction strategies include
subtracting a number in parts, adding up, and subtracting back.
Enduring Understanding:
• Understanding the equivalence of one group and the discrete units that comprise it
45
• Extending knowledge of the number system to 1,000
Students will be able to:
• Demonstrate fluency with the addition combinations up to 10 + 10
• Add multiples of 10 (up to 100) to and subtract them from 2-digit and small 3-digit numbers
• Solve addition problems with 2-digit numbers using strategies involving breaking numbers apart by place or adding one number in
parts
• Break up 3-digit numbers less than 200 into 100s, 10s, and 1s in different ways (e.g. 153 equals 1 hundred, 5 tens, and 3 ones; 15
tens and 3 ones; 14 tens and 13ones, etc.)
• Find combinations of 2-digit numbers that add to 100 or $1.00
• Read, write, and sequence numbers to 1,000
• Identify the value of each digit in a 3-digit number (100s, 10s, and 1s)
• Identify how many groups of 10 are in a 3-digit number (e.g. 153 has 15 groups of 10, plus 3 ones)
• Solve addition problems with 3-digit numbers (to 400) using strategies that involve breaking numbers apart, either by place value or
by adding one number in parts
• Solve subtraction story problems in contexts that include removing a part from a whole, comparing two quantities, or finding a
missing part
• Solve subtraction problems with 2-digit and 3-digit numbers (to 300) using strategies that involve either subtracting a number in
parts, adding up, or subtracting back
• Add multiples of 10 and 100 (to 1,000) to and subtract them from any 3-digit number
• Solve 3-digit addition problems using at least one strategy efficiently
• Demonstrate fluency with problems related to the addition combinations to 10 + 10 (the subtraction facts)
• Solve subtraction problems with 3-digit numbers using strategies that involve either subtracting a number in parts, adding up, or
subtracting back

Unit Summary: Operations and Algebra– (information adapted from TERC 2nd
Edition Guidelines)
Throughout 2nd
grade, students work on making sense of the action of different types of addition and subtraction problems and on
developing efficient strategies for solving them and for recording their work. They solve addition and subtraction problems in ways
that make sense to them and practice using particular strategies. Students study two particular strategies for addition –adding tens and
ones and adding one number in parts. By the end of the school year, students are expected to have at least one strategy that they can
use to accurately and efficiently solve an addition problem. In Grade 2, students’ work with place value becomes the basis for the
development of strategies for adding and subtracting 2-digit numbers. The two strategies for addition, adding by place and adding one
number in parts, and the strategy for subtraction of subtracting one number in parts, depend on an understanding of how to break
numbers into tens and ones. Students consider and practice two strategies for subtraction– subtracting in parts and adding up.
By the end of the year they are expected to have one strategy that they can use to accurately solve a subtraction problem Knowing the
single-digit addition combinations helps students as they work to develop efficient strategies for adding and subtracting. Students are
expected to be fluent with addition combinations up to 10 + 10 by the end of the year. Students use the relationship between addition
and subtraction to solve subtraction problems and to develop fluency with the subtraction expressions related to the addition
combinations to 10 + 10. Students use mathematical tools and representations to model and solve problems to clarify and
communicate their thinking. They are encouraged to show their mathematics work on paper in ways that make sense to them; many
use some combination of pictures, words, numbers and mathematical symbols and notation. Students are expected to use standard
notation to write equations to represent addition or subtraction problems. They are also expected to have methods for clearly showing
their work, including: sticker notation, numbers, equations, the number line and 100 Chart, or some combinations of these. The
algebra connections focus on addition and subtraction and how to apply the commutative and associative properties of addition as they
develop strategies for solving addition problems. There is also a focus on students’ application of the inverse relationship between
addition and subtraction and how algebraic ideas underlie what students are doing when they create equivalent expressions in order to
solve a problem (e.g., 5+ 9 = 4 + 10 or 5 + 9 = 5 + 10 - 1).

In Grade 3, students investigate the properties of multiplication and division, including the inverse relationship between these two
operations, and develop strategies for solving multiplication and division problems. Their work focuses on developing the idea that
multiplication involves some number of equal-sized groups, and that division also involves equal groups. Students are introduced to
arrays—rectangular arrangements of objects in rows and columns—to help them develop visual images that support their
understanding of multiplication. They use these rectangular arrays to represent the relationship between a product and its factors.
Students determine, describe, and compare sets of multiples, noticing their characteristics and relationships, and use these to
investigate important ideas about how multiplication works. They learn the multiplication combinations with products up to 50.

In grade 3, students use a variety of contexts to understand, represent, and combine fractions. Students work with halves, fourths,
eighths, thirds, and sixths as they learn how fractions represent equal parts of a whole. They learn the meanings of the numerator and
denominator of a fraction, so that when comparing unit fractions (fractions with a numerator of 1), they understand that the larger the
denominator the smaller the part of the whole. Students also gain experience with common equivalencies, for example, that 3/6 and
2/4 are both equal to 1/2. Using these equivalents in contexts, students find combinations of fractions that are equivalent to a whole or
to another fraction. Students are introduced to decimal fractions (0.50 and 0.25), using the context of money, and gain familiarity with
fraction and decimal equivalents involving halves and fourths.

Unit Summary: Patterns, Functions and Change– (information adapted from TERC 2nd
Edition Guidelines)
2nd
grade students explore situations with constant ratios in two contexts: building cube buildings with the same number of “rooms”
on each “floor” and covering a certain number of one pattern block shape with another pattern block shape. In both of these contexts,
students build and record how one variable changes in relation to the other. Tables are introduced and used as a central representation.
Organizing data in a table can help students uncover a rule that governs how one quantity changes in relation to another. Students
compare tables that show different relationships, both within the same context and between the two contexts, and notice how different
situations can have the same underlying relationship between quantities. Students also work with number sequences associated with
repeating patterns that reveal important characteristics of the pattern and provide an avenue into studying the number sequences
themselves. As students explore two-element and three-element repeating patterns, they encounter the odd number sequence, the even
number sequence, and three different “counting by 3” sequences. An important part of second-grade students’ work on pattern is
considering how and why different situations generate the same number sequence.
Enduring Understandings
Linear Relationships
• Describing and representing ratios
Using Tables and Graphs
• Using tables to represent change
Number Sequences

ratio situation (involving ratios of 1:2, 1:3, 1:4, 1:5, and 1:6)
• Complete and extend a table to match a situation involving a
constant ratio
• Extend a repeating pattern and determine what element of the
pattern will be in a particular position (e.g., the 16th position) if
the pattern keeps going
59
In 3rd
grade, students study situations of change as they examine temperature change over time in different places around the world,
analyze number sequences generated by repeating patterns, and consider a fantasy situation of constant change in which children
receive a certain number of Magic Marbles each day. They make, read, and compare line graphs that show a relationship between two
variables in situations of change over time. Students learn how to find the two values represented by a point on a coordinate graph by
referring to the scales on the horizontal and vertical axes. Students focus on seeing a graph as a whole, thinking about the overall
shape of a graph, and discussing what that overall shape shows about the change in the situation it represents. A class temperature
graph is created over the course of the year and discussed regularly. Students learn to read and interpret temperatures using standard
units. Students also use tables as a representation that shows how one variable changes in relation to another variable. Emphasis is on
how the numbers in the table relate to the situation they represent and to graphs of the same situation. Students use both tables and
graphs to examine and compare situations with a constant rate of change. They examine the relationship between columns of the table
and consider why the points on graphs representing such situations fall in a straight line. By examining the tables and graphs, students
consider any initial amount and the constant rate of change to develop general rules that express the relationship between two
variables in these contexts.

Unit Summary: Measurement and Data– (information adapted from TERC 2nd
Edition Guidelines)
Measurement: In Grade 2, students continue to develop their understanding of length and how it is measured. They first compare
lengths of objects by indirect and direct comparison and then use linear units to measure objects and compare measurements. Students
learn about iterating a unit and about the relationship between sizes of units and the results of measuring: the smaller the unit, the
greater the count for the same length. By discussing their methods for measuring, students learn that agreeing on a common unit is
critical for communicating measurement information to others and comparing results. This leads to work with standard measures:
inches, feet, and centimeters. As students move from using non-standard units (e.g., cubes) to measure objects to using standard tools
of measurement such as rulers and yardsticks, the emphasis is on making sure that their use of a measuring tool is connected to
making sense of length as an attribute of objects. Students begin their work with standard measurement tools by constructing their
own inch rulers, which helps foster not only an understanding of the conventional units, but also the process of measuring with a tool
and the principles that underlie the design and use of the tool. Students become accustomed to both systems of measurement: metric
and U.S. Standard. Students practice naming, notating, and telling time on digital and analog clocks. They also work with the idea
that time can be represented as a horizontal sequence. Students work with timelines, associating events with a particular time. Students
determine intervals of time with an emphasis on starting and ending times on the hour or half hour.
Enduring Understanding:
Linear Measurement
• Understanding length
• Using linear units
• Measuring with standard units
Time
• Representing time and calculating duration
Students will be able to :
• Identify sources of measurement error
• Recognize that the same count of different-sized units yields
different lengths
• Recognize that, when measuring the same length, larger units
yield smaller counts
• Measure objects using inches and centimeters
• Use a ruler to measure lengths longer than one foot
• Solve problems involving the beginning time of an event,
ending time of an event, and duration of the event; given two
of these, find the third for events beginning and ending on the
hour or half-hour
• Use a timeline to record and determine duration to the hour or
half-hour
2nd
grade students’ work on data begins with sorting activities in which they sort objects by their attributes, describing what
distinguishes one group from another. This early work in classification provides experience in considering only certain attributes of an
object while ignoring others. Students then apply these ideas to categorical data. They classify data with many different values, for
example the responses to the question, “What is your favorite weekend activity?” by grouping the data into categories (outdoor and
indoor activities; or things you do by yourself, things you do with one friend, and things you do with a group). By grouping the data in
63
different ways, students can use the same data to answer different questions. Students use a variety of representations: Venn
diagrams, towers of cubes, line plots, and their own representations. By comparing a variety of representations of the same data, they
learn how different representations can make different aspects of the data set more visible. Students are introduced to line plots and
other frequency distributions in which each piece of data is represented by one symbol (e.g., an X, a square, or a stick-on note). In
using this kind of representation, students have to think through the meaning of two ways numbers are used in describing the data:
Some numbers indicate the value of a piece of data (I have 8 pockets); other numbers indicate how often a particular data value occurs
(7 children have 8 pockets). Students describe data by considering the number of pieces of data that occur at each value, the mode and
the highest and lowest values. Through experiencing an entire data investigation from start to finish, students encounter many
of the same issues encountered by statisticians as they decide how to collect, keep track of, organize, represent, describe, and interpret
their data. They develop their own survey questions about “favorite things”, and collect and organize the survey data. They also
collect data from different grades about the number of teeth lost and represent and compare these data to their own class data.
Enduring Understanding:
Data Analysis
• Sorting and Classifying Data
• Representing Data
• Describing Data
• Designing and Carrying Out a Data Investigation
Students will be able to:
• Use a Venn diagram to sort data by two attributes
• Identify categories for a set of categorical data and organize
the data into the chosen categories
• Order and represent a set of numerical data
• Describe a numerical data set, including the highest and
lowest values and the mode
• Read and interpret a variety of representations of numerical
and categorical data
• Compare two sets of numerical data
Measurement work in Grade 3 includes linear measurement, area, angle measurement, volume, and temperature. Students measure
length and calculate perimeter with both U.S. standard units (inches, feet and yards) and metric units (centimeters and meters). Their
work focuses on using measurement tools accurately, and understanding the relationship between measures when the same length is
measured with different units. Students learn that the distance around the outside edges of a two-dimensional shape is called the
perimeter and consider how different shapes can have the same perimeter. They identify the amount of 2-D space a given shape covers
as its area, and learn that area is measured in square units. They identify the internal angle of a rectangle or square as 90 degrees.
They use right angles as a benchmark as they consider the sizes of angles of other polygons. Students also learn how the term degrees
is used differently when talking about measuring temperature. A class temperature graph is created over the course of the school year.
Students learn to read and interpret temperature using standard units. Students practice naming, notating, and telling time on digital
and analog clocks. They begin at the start of the year with telling time at five-minute intervals and then move to telling time at any
minute. Students also work on intervals of time. For example, they begin with a time and determine what time it will be after a given
number of minutes have passed or they determine how many minutes have passed when given a starting and ending time.

• Identify and find the area of given figures by counting whole
and partial square units
• Identify right angles and recognize whether an angle is larger
or smaller than a right angle
• Determine the number of cubes (volume) that will fit in the
box made by a given pattern
3rd grade students collect, represent, describe, and interpret data. They work with both categorical and numerical data, and consider
how to look at a data set as a whole and make statements about the whole group. In order to make sensible statements about a
categorical data set that has many different values, students group the data into categories that help them see the data as a whole.
Students order numerical data by value so that they can see the shape of the data—where the data are concentrated, where they are
spread out, which intervals have many pieces of data, and which have very few. They describe what values would be typical or
atypical, based on the data, and compare data sets in order to develop a sense of how data can be useful in describing and comparing
some characteristic of a group. Students work with their own data, creating representations, and then comparing and discussing these
representations. Students use double bar graphs to compare groups, including some in which the scales have intervals greater than 1.
Students interpret line plots and create their own line plots to represent numerical data. By conducting their own data investigations,
students consider how the question they pose and the way they conduct their study affect the resulting data.

Unit Summary: Geometry– (information adapted from TERC 2nd
Edition Guidelines)
In 2nd
grade, students describe, sort and compare two-dimensional (2-D) and three-dimensional (3-D) shapes and think about
questions like the following: What makes a rectangle a rectangle? How are rectangles different from squares? Second-grade students
study rectangles and rectangular prisms, and consider which properties are important in describing these shapes. They combine and
decompose both 2-D and 3-D shapes and explore the relationships between shapes, particularly as they work with pattern blocks and
Geoblocks. As they develop knowledge about how shapes are related, they are learning about the important features of shapes.
Students begin their work with arrays, a visual representation that they will continue to use in Grades 3 through 5. As students create
rectangles with square tiles, they learn about the structure of an array. In their study of arrays, work in geometry is closely linked with
ideas about number. Students develop a variety of numerical strategies, based on the number of tiles in a row and the number of rows,
to calculate the area of the rectangle. Students develop an understanding of mirror symmetry as they identify objects that have mirror
symmetry, create patterns and designs, fold and cut paper, and build 3-D structures with mirror symmetry. As they create and
investigate symmetrical shapes, they develop language and ideas about what symmetry is and how it behaves.
Enduring Understanding:
Features of Shapes
• Combining and decomposing 2-D and 3-D shapes
• Describing, identifying, comparing, and sorting 2-D and 3-D
shapes
• Exploring mirror symmetry
Area Measurement
• Visualizing the structure of arrays
Students will be able to:
• Identify the number of sides of a polygon
• Identify the number of rows and the number of squares in
each row in an array
• Identify rectangles as four-sided shapes with four right angles
• Identify the number of faces on a rectangular prism and show
which faces are congruent
• Make a symmetrical picture based on an image provided
3rd
grade students study the attributes of two-dimensional (2-D) and three-dimensional (3-D) shapes, and how these attributes
determine their classification. For example, a polygon is classified as a triangle or a quadrilateral based on the number of its sides.
Students also investigate the idea that one shape may have more than one name as they consider the properties of squares and
rectangles. They describe shapes by whether or not they are congruent to other shapes, and use geometric motions—slides
(translations),flips (reflections), and turns (rotations)—to determine if shapes are congruent. Students describe attributes of common
geometric solids (3-D shapes), such as how many edges and faces a solid shape has, or how a pyramid has triangular faces coming to a
point. They learn to distinguish between polyhedra (3-D shapes having only flat surfaces) and nonpolyhedra (3-D shapes that have
curved surfaces) and, within the class of polyhedra, between prisms and pyramids. Students learn about how 3-D objects can be
represented in 2-D space. For example, they design nets for open boxes that, if constructed in 3-D, would hold a certain number of
cubes. They determine the volume of the rectangular prisms that fit into a variety of open boxes. Students learn that the distance
around the outside edges of a two-dimensional shape is called the perimeter, and consider how different shapes can have the same
perimeter. They identify the amount of 2-D space a given shape covers as its area, and learn that area is measured in square units.
69
They identify the internal angle of a rectangle or square as 90 degrees. They use right angles as a benchmark as they consider the sizes
of angles of other polygons.
Enduring Understanding:
Features of Shape
• Describing and classifying 2-D figures
• Describing and measuring angles
• Describing properties of 3-D shapes
• Translating between 2-D and 3-D shapes
Linear Measurement
• Measuring length
• Measuring with standard units
• Understanding and finding perimeter

• Structuring rectangular prisms and determining their volume
Students will be able to:
• Identify and accurately measure the perimeter of a shape
using U.S. standard and metric units
• Identify and find the area of given figures by counting whole
and partial square units
• Identify triangles as three-sided closed shapes with three
vertices and three angles
• Identify right angles, and recognize whether an angle is larger
or smaller than a right angle

Unit Overviews of TERC 4th
Grade Curriculum
(From TERC 2nd
edition overview materials)
Number and Operations: Whole Numbers Work focuses on extending knowledge of the base ten number system to 10,000.
Multiplication and division are the major focus of students’ work in number and operations. Students use models, representations, and
story contexts to help them understand and solve multiplication and division problems. In addition and subtraction, students
refine and compare strategies for solving problems with 3-4 digits. By the end of the year, students are expected to solve addition and
subtraction problems efficiently; know their multiplication combinations to 12 x 12 and use the related division facts, and to solve 2- x
2-digit multiplication problems and division problems with 1-2 digit divisors.
Number and Operations: Fractions and Decimals The major focus of work is on building students’ understanding of the meaning,
order, and equivalencies of fractions and decimals. They work with fractions in the context of area, as a group, and on a number line.
Students are introduced to decimal fractions as an extension of the place value system. They reason about fraction comparisons, order
fractions on a number line, and use representations and reasoning to add fractions and decimals.
Geometry and Measurement Students expand their understanding of how the attributes of 2-D and 3-D shapes determine their
classification. Students consider attributes of 2-D shapes, such as number of sides, the length of sides, parallel sides, and the size of
angles. Students also describe attributes and properties of geometric solids (3-D shapes). Measurement work includes linear
measurement (with both U.S standard and metric units), area, angle measurement, and volume. Students work on understanding
volume by structuring and determining the volume of a rectangular prism.
Patterns and Functions Students create tables and graphs for situations with a constant rate of change and use them to compare
related situations. By analyzing tables and graphs, students consider how the starting amount and the rate of change define the
relationship between the two quantities and develop rules that govern that relationship.
Data Analysis and Probability Students collect, represent, describe, and interpret numerical data. Their work focuses on describing
and summarizing data for comparing two groups. They develop conclusions and make arguments, based on the evidence they collect.
In their study of probability, students describe and predict what events are impossible, unlikely, likely, or certain. Students
reason about how the theoretical chance (or theoretical probability) of, for example, rolling 1 on a number cube compares to what
actually happens when a number cube is rolled repeatedly.

(From TERC 2nd
edition overview materials)
Number and Operations: Whole Numbers Students practice and refine the strategies they know for addition, subtraction,
multiplication, and division of whole numbers as they improve computational fluency and apply these strategies to solving problems
with larger numbers. They expand their knowledge of the structure of place value and the base-ten number system as they
work with numbers in the hundred thousands and beyond. By the end of the year, students are expected to know their division facts
and to efficiently solve computation problems involving whole numbers for all operations.
Number and Operations: Fractions, Decimals, and Percents. The major focus of the work with rational numbers is on
understanding relationships among fractions, decimals, and percents. Students make comparisons and identify equivalent fractions,
decimals and percents. They order fractions and decimals, and develop strategies for adding fractions and decimals to the thousandths.
Geometry and Measurement Students develop their understanding of the attributes of 2-D shapes, examine the characteristics of
polygons, including a variety of triangles, quadrilaterals, and regular polygons. They also find the measure of angles of polygons. In
measurement, students use standard units of measure to study area and perimeter and to determine the volume of prisms and other
polyhedra.
Patterns and Functions Students examine, represent, and describe situations in which the rate of change is constant. They create
tables and graphs to represent the relationship between two variables in a variety of contexts and articulate general rules using
symbolic notation for each situation. Students create graphs for situations in which the rate of change is not constant and consider why
the shape of the graph is not a straight line.
Data Analysis and Probability Work focuses on comparing two sets of data collected from experiments developed by the students.
They represent, describe, and interpret this data. In their work with probability, students describe and predict the likelihood of events
and compare theoretical probabilities with actual outcomes of many trials. They use fractions to express the probabilities of the
possible outcomes.

Observing the Students: In each unit, bulleted lists of questions that suggest what teachers might focus on as they observe students
and look at their written work for particular activities are included. They also offer ideas about what's important about the activity, and
what math ideas children are likely to struggle with.
Formative Assessment/ Teacher Checkpoints: In each unit, there is a suggested time to 'check in,' to pause in the teaching sequence
and get a sense of how both the class as a whole and individual students in your class are doing with the mathematics at hand. They
usually come earlier in a unit, and are meant to give a sense of how your class is doing, and how you might want to adapt the pacing of
the rest of the unit.
Summative Assessment Activities: Assessment activities are embedded in each unit to help examine specific pieces of student work,
figure out what it means, and provide feedback. These often come towards the end of a unit and are meant to offer a picture of how
students have mastered the mathematics of the unit at hand. Each is a learning experience in and of itself, as well as an opportunity to
gather evidence about students' mathematical understandings. These activities often have Teacher Notes associated with them that
discuss the problem, provide support in analyzing student work and responses, and offer guidance about next steps for the range of
students in a class.
Portfolios/Choosing Student Work to Save: At the end of the last investigation of each unit, there are suggestions for choosing
student work to save to develop a portfolio of a student's work over time.

Unit Summary: Number Sense and Numeration– (information adapted from TERC 2nd
Edition Guidelines)
In Grade 4, students extend their knowledge of the base-ten number system, working with numbers up to 10,000. Their work focuses
on understanding the structure of 10,000 and how numbers are related within that structure, recognizing the place value of digits in
large numbers, and using place value to determine the magnitude of numbers. By discussing, refining and comparing their strategies
for adding and subtracting 3- and 4-digit numbers, including studying the U.S. algorithm for addition, students continue expanding
their understanding of addition and subtraction. Their strategies should involve good mental arithmetic, estimation, clear and concise
notation, and a sound understanding of number relationships. By identifying and naming addition and subtraction strategies that they
are using, students are adding to the repertoire of strategies they can use for flexible and fluent computation. Further, they consider
how and why certain methods work. For example, some students change one or both numbers in an addition or subtraction expression
to create an easier problem, then compensate as needed for that change. To help them make good decisions about strategies for
subtraction and continue to develop their understanding of how subtraction operates, students use visual representations, such as
number lines and 100 Charts, and story contexts that include several types of subtraction situations—removal (or take away),
comparison, and missing parts. Students focus particularly on missing part problems in the context of distance: Some students
visualize a problem like this one as adding up from the distance traveled to the total distance, while others visualize subtracting the
distance traveled from the total distance.
Enduring Understanding:
The Base Ten Number System
• Extending knowledge of the base-ten number system to
10,000
Computational Fluency
• Adding and subtracting accurately and efficiently
Whole Number Operations
• Describing, analyzing, and comparing strategies for adding
and subtracting whole numbers
• Understanding different types of subtraction problems
Students will be able to:
• Read, write, and sequence numbers to 10,000
• Add and subtract multiples of 10 (including multiples of 100
and 1,000) fluently
• Solve addition problems efficiently, choosing from a variety
of strategies
• Solve subtraction problems with 3-digit numbers by using at
least one strategy efficiently
In Grade 5, students extend their knowledge of the base ten number system, working with numbers in the hundred thousands and
beyond. In their place value work, students focus on adding and subtracting multiples of 100 and 1,000 to multi-digit numbers and
explaining the results. This work helps them develop reasonable estimates for sums and differences when solving problems with large
numbers. Students apply their understanding of addition to multi-step problems with large numbers. They develop increased fluency
as they study a range of strategies and generalize the strategies they understand to solve problems with very large numbers. Students
practice and refine their strategies for solving subtraction problems. They also classify and analyze the logic of different strategies;
they learn more about the operation of subtraction by thinking about how these strategies work. Students consider which subtraction

problems can be solved easily by changing one of the numbers and then adjusting the difference. As they discuss and analyze this
approach, they visualize important properties of subtraction. By revisiting the steps and notation of the U.S. algorithm for subtraction
and comparing it to other algorithms, students think through how regrouping enables subtracting by place, with results that are all in
positive numbers.

Unit Summary: Operations and Algebra– (information adapted from TERC 2nd
Edition Guidelines)
In Grade 4, this component of students’ work centers on reasoning about numbers and their factors and multiples, using models,
representations, and story contexts to help them visualize and solve multiplication and division problems; and understanding the
relationship between multiplication and division. Students learn the multiplication combinations (facts) to 12 x 12 so that they can use
these fluently to solve both multiplication and division problems. They develop strategies for solving multiplication and division
problems based on looking at the problem as a whole, thinking about the relationships of the numbers in the problem, and choosing an
approach they can carry out easily and accurately, often breaking the numbers apart or changing the numbers in some way.
Visualizing how multiplication works is critical in applying the distributive property to solve problems and in keeping track of parts of
the problem. Learning to multiply by multiples of 10 is also a key component of this work. Students interpret and solve division
problems, both in story contexts and numerical contexts. They work with both grouping and sharing situations, and consider how to
make sense of a remainder within the context of the problem. They use the inverse relationship between multiplication and division to
solve division problems, including those related to the multiplication combinations to 12 x 12 (the division “facts”), and problems in
which 3-digit numbers are divided by 1-digit and small 2-digit divisors.

numbers (e.g. 12, 15, 20), using strategies that involve breaking
the numbers apart
• Solve division problems (2- and small 3-digit numbers
divided by 1-digit numbers) including some that result in a
remainder
• Use story problems, pictures, or concrete models to represent
division situations
• Multiply by 10 and multiples of 10
• Demonstrate fluency with multiplication combinations to 12
x 12

• Solve division problems with 1- and small 2-digit divisors by
using at least one strategy efficiently
91
The major focus of the work on rational numbers in grade 5 is on understanding relationships among fractions, decimals, and
percents. Students make comparisons and identify equivalent fractions, decimals, and percents, and they develop strategies for
adding and subtracting fractions and decimals. In a study of fractions and percents, students work with halves, thirds, fourths, fifths,
sixths, eighths, tenths, and twelfths. They develop strategies for finding percent equivalents for these fractions so that they are able to
move back and forth easily between fractions and percents and choose what is most helpful in solving a particular problem, such as
finding percentages or fractions of a group. Students use their knowledge of fraction equivalents, fraction-percent equivalents, the
relationship of fractions to landmarks such as ½, 1, and 2, and other relationships to decide which of two fractions is greater. They
carry out addition and subtraction of fractional amounts in ways that make sense to them by using representations such as rectangles,
rotation on a clock, and the number line to visualize and reason about fraction equivalents and relationships. Students continue to
develop their understanding of how decimal fractions represent quantities less than 1 and extend their work with decimals to
thousandths. By representing tenths, hundredths, and thousandths on rectangular grids, students learn about the relationships among
these numbers—for example, that one tenth is equivalent to ten hundredths and one hundredth is equivalent to ten thousandths—and
how these numbers extend the place value structure of tens that they understand from their work with whole numbers. Students extend
their knowledge of fraction-decimal equivalents by studying how fractions represent division and carrying out that division to find an
equivalent decimal. They compare, order, and add decimal fractions (tenths, hundredths, and thousandths) by carefully identifying the
place value of the digits in each number and using representations to visualize the quantities represented by these numbers.

Unit Summary: Patterns, Functions, and Change– (information adapted from TERC 2nd
Edition Guidelines)
In Grade 4, students use graphs and tables to represent change. One focus of their work is how a line graph shows the rate of change,
as they consider questions such as the following: “How does this graph show the parts of the story that are about speed and the parts of
the story that are about changes in speed?” “What was the rate of growth for this plant? When was it growing more slowly or more
quickly?” Students create tables and graphs for situations with a constant rate of change and use them to compare related situations.
By analyzing tables and graphs, students consider how the starting amount and the rate of change define the relationship between the
two quantities (e.g., number of rounds, total number of pennies), and develop rules that govern that relationship. At first students
articulate these rules in words (as they did in grade 3), but they also are introduced to the use of symbolic notation and equations to
represent their rules. They use these rules to determine the value of one variable when the value of the other is known.
Enduring Understanding:
Using Tables and Graphs
• Using tables to represent change
• Using tables to represent change
Linear Relationships
• Describing and representing a constant rate of change
Students will be able to:
• Connect tables and graphs of change over time to each other
and to the situations they represent.
• Make a graph on a coordinate grid from a table of values.
• Describe how a graph shows change: where the rate of
change is increasing, decreasing, or remaining constant, and
how differences in steepness represent differences in the rate of
change.
• Take into account the starting amount and the amount of
change in describing and comparing situations of constant
change.
• In a situation of constant change, write rules (using words or
arithmetic expressions) to determine the value of one quantity,
given the value of the other.
In Grade 5, students continue their work from Grades 3 and 4 by examining, representing, and describing situations in which the rate
of change is constant. Students create tables and graphs to represent the relationship between two variables in a variety of contexts.
They also articulate general rules for each situation. For example, consider the perimeters of the following set of rectangles made from
rows of tiles with three tiles in each row: If the value of one variable (the number of rows of three tiles) is known, the corresponding
value of the other variable (the perimeter of the rectangle) can be calculated. Students express these rules in words and then in
symbolic notation. For example: For the first time in Grade 5, students create graphs for situations in which the rate of change is itself
changing–for example, the change in the area of a square as a side increases by a constant increment–and consider why the shape of
the graph is not a straight line as it is for situations with a constant rate of change. Throughout their work, students move among
tables, graphs, and equations and between those representations and the situation they represent. Their work with symbolic notation
97
is closely related to the context in which they are working. By moving back and forth between the contexts, their own ways of
describing general rules in words, and symbolic notation, students learn how this notation can carry mathematical meaning.

Unit Summary: Measurement and Data– (information adapted from TERC 2nd
Edition Guidelines)
In Grade 4, students continue to build on measurement work from earlier grades, which includes linear measurement, area, angle
measurement, and volume. They use both U.S. standard units (inches, feet and yards) and metric units (centimeters and meters) to
measure lengths up to 100 feet, and they determine the perimeter of various shapes. They measure the area of both regular and
nonregular polygons in square units by using the understanding that area can be decomposed—that is, broken into smaller parts.
Students work on determining the size of angles relative to a right angle, or 90 degrees. For instance, if three equal angles form a right
angle, then each of the smaller angles must be 1/3 of 90 degrees or 30 degrees.
Enduring Understanding:
Linear Measurement
• Measuring with standard units
Area Measurement
• Understanding and finding area
Volume
• Structuring rectangular prisms and determining their volume
Students will be able:
• Use appropriate measurement tools to measure distance
• Identify quadrilaterals as any four-sided closed shape
• Know that a right angle measures 90 degrees, and use this as
a landmark to find angles of 30, 45, and 60 degrees
• Find the area of polygons using a square unit of measure
• Identify 2-dimensional silhouettes of 3-dimensional solids
(e.g. a cone can project a triangular silhouette)
• Draw 2-D representations showing different perspectives of a
3-D object
• Find the volume of cube buildings and rectangular prisms
In their work with measurement in grade 5, students further develop their understanding of the attributes of two-dimensional (2-D)
shapes, find the measure of angles of polygons, determine the volume of three-dimensional (3-D) shapes, and work with area and
perimeter. Students examine the characteristics of polygons, including a variety of triangles, quadrilaterals, and regular polygons.
They consider questions about the classification of geometric figures. They investigate angle sizes in a set of polygons and measure
angles of 30, 45, 60, 90, 120, and 150 degrees by comparing the angles of these shapes. Students also investigate perimeter and area.
They consider how changes to the shape of a rectangle can affect one of the measures and not the other (e.g., two shapes that have the
same area don’t necessarily have the same perimeter), and examine the relationship between area and perimeter in similar figures.
Students continue to develop their visualization skills and their understanding of the relationship between 2-D pictures and the 3-D
objects they represent. Students determine the volume of boxes (rectangular prisms) made from 2-D patterns and create patterns for
boxes to hold a certain number of cubes. They develop strategies for determining the number of cubes in 3-D arrays by mentally
organizing the cubes—for example as a stack of three rectangular layers, each three by four cubes. Students deepen their
understanding of the relationship between volume and the linear dimensions of length, width, and height. Once students have
developed viable strategies for finding the volume of rectangular prisms, they extend their understanding of volume to other solids
such as pyramids, cylinders, and cones, measured in cubic units.

Unit Summary: Geometry– (information adapted from TERC 2nd
Edition Guidelines)
Grade 4 students expand their understanding of the attributes of two-dimensional (2-D) and three dimensional (3-D) shapes, and how
these attributes determine their classification. Students consider the various attributes of 2-D shapes, such as number of sides, the
length of sides, parallel sides, and the size of angles, expanding their knowledge of foursided figures (quadrilaterals) to include
parallelograms, rhombuses, and trapezoids. Students also describe attributes and properties of geometric solids (3-D shapes), such as
the shape and number of faces, the number and relative lengths of edges, and the number of vertices. They describe classes of shapes,
for example, how a pyramid has triangular faces meeting at a point. They visualize how 3-D shapes can be represented in two
dimensions, for example, by silhouettes projected by 3-D objects and structures.

Membership in Groups
Children understand that everyone holds membership in a variety of groups,
beginning with the family. They consider how groups shape our lives, how
we, in turn, can shape groups, and they develop a sense of civic and social
responsibility. Through this study, children will see themselves as holding
membership in a variety of groups from their family, to the classroom, to the
larger community.
Diversity and Continuity of Living Things
As children explore the diversity and continuity of all living things, they
understand that all species belong to groups based on their characteristics;
these characteristics are hereditary. All species, including humans, have a
cycle of life.
Man’s Impact on Life Cycles and Systems
The natural world works in a series of cycles and systems. Children understand that
human life has a beginning, a time of growth, and an ending. They acquire a basic
knowledge of the body’s needs and its functions and adopt personal habits that promote
wellness. Extending this concept, children learn that species within an ecosystem have
unique structures that allow them to survive in that ecosystem. Children will see the
cycle of life around them in nature. This understanding extends to an understanding that
all organisms are all connected as a part of the larger ecosystem. Children develop an
understanding that man’s decisions can impact the balance of the larger ecosystems and
the sustainability of resources. Beginning with their families and classrooms, children
understand that people have a civic and global responsibility to use the earth’s resources
wisely.

Fundamental Wants
All species, including humans have basic fundamental wants. Children
distinguish wants from wants, and understand that due to scarcity,
individuals, families, classrooms, must make choices in their activities and
consumption of their goods and services. Science has provided ways that
humans can better meet their wants. As humans use natural resources to meet
their wants, they may have long term impacts on the environment and the
future availability of resources. Children discover the importance of carefully
using the precious resources of our earth, becoming responsible producers,
consumers, and conservers.
Earth Systems and Human Interactions
Weather/Soils
Children discover that the flow of energy drives processes of change and all biological,
chemical, physical and geological systems. Earth’s dynamic systems are made up of the
solid earth (geosphere), the oceans, lakes, rivers, glaciers and ice sheets (hydrosphere),
the atmosphere, and organisms. Interactions and changes in these spheres have resulted
in ongoing changes to the system. These changes also impact human groups and their
survival. Some of the changes can be measured on a human time scale, but others occur
so slowly that they must be inferred from geological evidence.

Place in Time and Space
Humans have always had a capacity to place themselves in time and space.
Students explore the intergenerational connections of the various groups they
belong to. They learn about the history and traditions of their own cultures.
They gain perspective about where they are located spatially on the planet
and in the universe.
The Flow of Energy and Human Wants
Children discover that the flow of energy drives processes of change and all biological,
chemical, physical and geological systems. In this study, children understand that energy
takes many forms. People use energy to do work. There are various sources of energy
that people can harness to use. Some are renewable sources and others will be depleted
at some point. People also seek to understand materials and their properties. The
transfer of energy can change materials into different forms (water, ice, steam).
Different materials are best suited to various uses by man because of their properties.

Responsibility to Group Membership
Diversity and Continuity of Living Things
Humans have established systems that structure their participation in groups.
Children learn the various ways that governments are structured; develop an
understanding of the principles of a representative democracy and the
responsibilities they have as citizen holding both rights and responsibilities in
society. They are challenged to be a good citizen in their school and beyond, and to
understand that group membership means having responsibilities, as well as rights.
Building on the study of the 5-7 program, children continue to explore the diversity
and continuity of living things, and the relationship of humans to the natural world.
They understand how humans as organisms are similar and different from other
organisms, and that each has a place in the natural world.
Life Cycles and Systems/ Historian’s perspective
The natural world works in a series of cycles and systems. This understanding
extends to an understanding that we are all connected as a part of the larger
ecosystem. This ecosystem depends on a system of consumers and producers.
Species within an ecosystem have unique structures that allow them to survive in
that ecosystem. As one part of the ecosystem changes, other parts will be affected.
Children develop an understanding that man’s decisions can impact the balance of
the larger ecosystems and the sustainability of resources. The perspective of the
historian can help us to understand how man has impacted the regions around them
and how the resulting changes in ecosystems have impacted communities.

Economics of wants and fundamental wants
Children identify human wants, and understand that due to scarcity, individuals,
families, communities, and societies as a whole, must make choices in their
activities and consumption of their goods and services. People make decisions
about production and consumption by considering the costs and benefits of various
choices. Science has provided ways that humans can better meet their wants. As
humans use natural resources to meet their wants, they may have long term impacts
on the environment and the future availability of resources. Children discover the
importance of carefully using the precious resources of our earth, becoming
responsible producers, consumers, and conservers.
Producing and Consuming
All people engage in making and using things. Children recognize the value and
dignity of work. They learn that human economic systems serve to provide a
method for people to distribute goods and services to meet their wants. They
understand that due to scarcity, individuals, families, and communities and
societies as a whole must make choices in their activities and consumption of their
goods and services. Life for all of us involves producing and consuming.
Knowledge of materials and their properties helps man to match materials to
products for consumption.

Study Three—Place in Time and Space
Geological History, Human History
Humans have always had a capacity to place themselves in time and space.
Students develop an understanding of the concept of regions, how regions and
places are defined both by land forms and by human interactions and characteristics
(cultures, linguistics, etc.). Students understand that they are part of a larger history
of humanity and the geological history of the earth.
Earth’s Energy and Geological Systems
Children discover that the flow of energy drives processes of change and all
biological, chemical, physical and geological systems. Earth’s dynamic systems
are made up of the solid earth (geosphere), the oceans, lakes, rivers, glaciers and
ice sheets (hydrosphere), the atmosphere, and organisms. Interactions and changes
in these spheres have resulted in ongoing changes to the system. Some of the
changes can be measured on a human time scale, but others occur so slowly that
they must be inferred from geological evidence. These changes also impact human
groups and the energy and mineral resources in various regions available to
humans to meet their wants.

The Purpose of Governments/ Scientific Advances
This study builds on the understandings of group
functioning, rights and responsibilities from the 5-9
(K-3rd grade) program. The study focuses
specifically on civic responsibility. Children learn
the various ways that governments are structured and
develop an understanding of the principles of a
representative democracy and the responsibilities
they have as a citizen holding both rights and
responsibilities in society. They are challenged to be
a good citizen in their school and beyond and to
understand that citizenship in groups and the U.S.
means having responsibilities as well as rights.
Children explore various scientific advances, laws
that have been instituted related to scientific
knowledge, and how government influences the uses
of our natural resources.
Energy exchanges and Systems
The Historical Perspective Science
Children discover that the flow of energy drives processes of
change and all biological, chemical, and physical systems.
In this study children learn that energy stored in a variety of
systems can be transformed into their energy forms, which
influence many facets of daily life. People use a variety of
resources to meet the basic energy wants of life. Some of
these resources cannot be replaced and others exist in vast
quantities. The structure of materials influences their
physical properties, chemical reactivity, and use. The
exchange of energy can change matter from one form to
another making a material more suitable for a specific
purpose. Many Scientists have contributed to our
understanding the biological, chemical and physical nature
of energy. Historians contribute to our understanding of
how these scientists worked, their culture, society’s
responses to their work, and the resources they had for their
work.
The diversity of life and life processes/
cycles across nature and human cultures
The natural living world is composed of a diverse group
of organisms and species. Man seeks to understand the
similarities and differences between them including
structure of species, life cycles, and the interdependency
between them. Some scientists view some animal
groups as having cultures or norms, e.g. Jane Goodall
and her study of chimpanzees. Man uses this
knowledge to improve his own life experience. Like the
organisms in the natural world around us, people of
various cultures have a life cycle and traditions that go
with various stages of their life cycles. Children come
to appreciate the diversity across cultures,
understanding that cultures address childhood,
adolescence, adulthood and aging in similar and
different ways.

Place in Time and Space - The Universe through
the eyes of science and history
Building on the concept that humans seek to place
themselves in time and space, children will develop
an appreciation for the earth in relationship to the
universe. Humans have always sought to explore and
understand our place in the universe. Combining
scientific thinking and the lens of the historian,
children will develop an understanding of the solar
system and track the history of human discovery
related to space exploration beginning with the
earliest scientist and moving to man’s most recent
explorations.
Producing and Consuming – in Nature and Human
Interactions
Production and consumption occurs as a human interaction
among humans and as a natural interaction in ecosystems.
All people engage in making and using things. Children
learn the various ways that different cultures produce goods,
what they value for production, how they structure
economic systems that support production and consumption,
and how cultures use the regional resources and trade
globally to meet various wants of different societies. They
understand that due to scarcity, communities and societies
must make choices in their activities and consumption of
goods and services. Various aspects of science contribute to
decisions about production and consumption. The
ecosystem is dependent on the concept of producers and
consumers. When man utilizes the natural resources around
him, he may impact the balance of the ecosystem impacting
his long-term ability to meet man’s wants. The production
and consumption of energy impacts the ability of a society
to produce goods and services to meet their wants.
Knowledge of materials and their properties helps man to
match materials to products.
Earth’s Dynamic Systems/Earth Regions/
and the Impact on Culture Earth’s dynamic systems are made up of the solid earth
(geosphere), the oceans, lakes, rivers, glaciers and ice
sheets (hydrosphere), the atmosphere, and organisms.
Interactions and changes in these spheres have resulted
in ongoing changes to the system. Some of the changes
can be measured on a human time scale, but others
occur so slowly that they must be inferred from
Geological evidence. These changes also impact human
groups, their resources, the cultures that develop and
interactions and exchanges between cultures. Groups
may choose to settle in particular areas because of the
various geological aspects of the region providing for
such things as good trade routes, protection from others,
and ease of communication. The history of a region
helps us to understand the development of cultural
uniqueness and the impact of natural events on the
people living in a region.
