Counting and CardinalityKnow number names and the count sequence.K.CC.1 Count to 100 by ones and by tens.K.CC.2 Count forward beginning from a given number within the known
sequence (instead of having to begin at 1).K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a
written numeral 0-20 (with 0 representing a count of no objects).
Count to tell the number of objects.K.CC.4 Understand the relationship between numbers and quantities;
connect counting to cardinality. a. When counting objects, say the number names in the standard
order, pairing each object with one and only one number name and each number name with one and only one object.
b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
c. Understand that each successive number name refers to a quantity that is one larger.
K.CC.5 Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
Compare numbers.K.CC.6 Identify whether the number of objects in one group is greater than,
less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. (Note: Include groups with up to ten objects.)
K.CC.7 Compare two numbers between 1 and 10 presented as written numerals.
operations and algebraiC thinKingunderstand addition as putting together and adding to, and understand subtraction as taking apart and taking from.K.oa.1 Represent addition and subtraction with objects, fingers, mental
images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. (Note: Drawings need not show details, but should show the mathematics in the problem – this applies wherever drawings are mentioned in the Standards.)
K.oa.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
K.oa.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
K.oa.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
K.oa.5 Fluently add and subtract within 5.
number and operations in base tenWork with numbers 11 – 19 to gain foundations for place value.K.nbt.1 Compose and decompose numbers from 11 to 19 into ten ones and
some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 +8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
measurement and datadescribe and compare measurable attributes.K.md.1 Describe measurable attributes of objects, such as length or weight.
Describe several measurable attributes of a single object.K.md.2 Directly compare two objects with a measurable attribute in
common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
Classify objects and count the number of objects in each category.K.md.3 Classify objects into given categories; count the numbers of objects
in each category and sort the categories by count. (Note: Limit category counts to be less than or equal to 10.)
geometryidentify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).K.g.1 Describe objects in the environment using names of shapes, and
describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
K.g.2 Correctly name shapes regardless of their orientations or overall size.K.g.3 Identify shapes as two-dimensional (lying in a plane, “flat”) or three-
dimensional (“solid”).
analyze, compare, create, and compose shapes.K.g.4 Analyze and compare two- and three-dimensional shapes, in different
sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/ “corners”) and other attributes (e.g., having sides of equal length).
K.g.5 Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
K.g.6 Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”
Kindergarten – Standards 1. representing, relating and operating on whole numbers, initially with
sets of objects – Students use numbers, including written numerals, to represent quantities and to solve quantitative problems, such as counting objects in a set; counting out a given number of objects; comparing sets or numerals; and modeling simple joining and separating situations with sets of objects, or eventually with equations such as 5 + 2 = 7 and 7 – 2 = 5. (Kindergarten students should see addition and subtraction equations, and student writing of equations in kindergarten is encouraged, but it is not required.) Students choose, combine, and apply effective strategies for answering quantitative questions, including quickly recognizing the cardinalities of small sets of objects, counting and producing sets of given sizes, counting the number of objects in combined sets, or counting the number of objects that remain in a set after some are taken away.
2. describing shapes and space – Students describe their physical world using geometric ideas (e.g., shape, orientation, spatial relations) and
vocabulary. They identify, name, and describe basic two-dimensional shapes, such as squares, triangles, circles, rectangles, and hexagons, presented in a variety of ways (e.g., with different sizes and orientations), as well as three-dimensional shapes such as cubes, cones, cylinders and spheres. They use basic shapes and spatial reasoning to model objects in their environment and to construct more complex shapes.

operations and algebraiC thinKingrepresent and solve problems involving addition and subtraction.1.oa.1 Use addition and subtraction within 20 to solve word problems
involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (Note: See Glossary, Table 1.)
1.oa.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
understand and apply properties of operations and the relationship between addition and subtraction.1.oa.3 Apply properties of operations as strategies to add and subtract.
(Note: Students need not use formal terms for these properties.) Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
1.oa.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
add and subtract within 20.1.oa.5 Relate counting to addition and subtraction (e.g., by counting on 2 to
add 2).1.oa.6 Add and subtract within 20, demonstrating fluency for addition and
subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Work with addition and subtraction equations.1.oa.7 Understand the meaning of the equal sign, and determine if
equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
1.oa.8 Determine the unknown whole number in an addition or subtraction equation relating to three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = o – 3, 6 + 6 = o.
number and operations in base tenextend the counting sequence.1.nbt.1 Count to 120, starting at any number less than 120. In this range,
read and write numerals and represent a number of objects with a written numeral.
understand place value.1.nbt.2 Understand that the two digits of a two-digit number represent
amounts of tens and ones. Understand the following as special cases: a. 10 can be thought of as a bundle of ten ones – called a “ten.” b. The numbers from 11 to 19 are composed of a ten and one, two,
three, four, five, six, seven, eight, or nine ones. c. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two,
three, four, five, six, seven, eight, or nine tens (and 0 ones).1.nbt.3 Compare two two-digit numbers based on meanings of the tens and
ones digits, recording the results of comparisons with the symbols >, =, and <.
use place value understanding and properties of operations to add and subtract.1.nbt.4 Add within 100, including adding a two-digit number and a one-digit
number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
First Grade – Standards
1. developing understanding of addition, subtraction, and strategies for addition and subtraction within 20 – Students develop strategies for adding and subtracting whole numbers based on their prior work with small numbers. They use a variety of models, including discrete objects and length-based models (e.g., cubes connected to form lengths), to model add-to, take-from, put-together, take-apart, and compare situations to develop meaning for the operations of addition and subtraction, and to develop strategies to solve arithmetic problems with these operations. Students understand connections between counting and addition and subtraction (e.g., adding two is the same as counting on two). They use properties of addition to add whole numbers and to create and use increasingly sophisticated strategies based on these properties (e.g., “making tens”) to solve addition and subtraction problems within 20. By comparing a variety of solution strategies, children build their understanding of the relationship between addition and subtraction.
2. developing understanding of whole number relationship and place value, including grouping in tens and ones – Students develop, discuss, and use efficient, accurate, and generalizable methods to add within 100 and subtract multiples of 10. The compare whole numbers (at least to 100) to develop understanding of and solve problems involving their relative sizes. They think of whole numbers between 10 and 100 in terms of tens and ones (especially recognizing the numbers 11 to 19 as composed of a ten and some ones). Through activities that build number sense, they understand the order of the counting numbers and their relative magnitudes.
3. developing understanding of linear measurement and measuring lengths as iterating length units – Students develop an understanding of the meaning and processes of measurement, including underlying concepts such as iterating (the mental activity of building up the length of an object with equal-sized units) and the transitivity principle for indirect measurement. (Note: students should apply the principle of transitivity of measurement to make direct comparisons, but they need not use this technical term.)
4. reasoning about attributes of, and composing and decomposing geometric shapes – Students compose and decompose plane or solid figures (e.g., put two triangles together to make a quadrilateral) and build understanding of part-whole relationships as well as the properties of the original and composite shapes. As they combine shapes, they recognize them from different perspectives and orientations, describe their geometric attributes, and determine how they are alike and different, to develop the background for measurement and for initial understandings of properties such as congruence and symmetry.

1.nbt.5 Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
1.nbt.6 Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
measurement and datameasure lengths indirectly and by iterating length units.1.md.1 Order three objects by length; compare the lengths of two objects
indirectly by using a third object.1.md.2 Express the length of an object as a whole number of length units, by
laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
tell and write time.1.md.3 Tell and write time in hours and half-hours using analog and digital clocks.
represent and interpret data.1.md.4 Organize, represent, and interpret data with up to three categories;
ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
geometryreason with shapes and their attributes.1.g.1 Distinguish between defining attributes (e.g., triangles are closed and
three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
1.g.2 Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Note: Students do not need to learn formal names such as “right rectangular prism.”)
1.g.3 Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

operations and algebraiC thinKingrepresent and solve problems involving addition and subtraction.2.oa.1 Use addition and subtraction within 100 to solve one- and two-step
word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. (Note: See Glossary, Table 1.)
add and subtract within 20.2.oa.2 Fluently add and subtract within 20 using mental strategies. (Note:
See standard 1.OA.6 for a list of mental strategies). By end of Grade 2, know from memory all sums of two one-digit numbers.
Work with equal groups of objects to gain foundations for multiplication.2.oa.3 Determine whether a group of objects (up to 20) has an odd or even
number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
2.oa.4 Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
number and operations in base tenunderstand place value.2.nbt.1 Understand that the three digits of a three-digit number represent
amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
a. 100 can be thought of as a bundle of ten tens – called a “hundred.” b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one,
two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
2.nbt.2 Count within 1000; skip-count by 5s, 10s, and 100s.2.nbt.3 Read and write numbers to 1000 using base-ten numerals, number
names, and expanded form.2.nbt.4 Compare two three-digit numbers based on meanings of the
hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
use place value understanding and properties of operations to add and subtract.2.nbt.5 Fluently add and subtract within 100 using strategies based on
place value, properties of operations, and/or the relationship between addition and subtraction.
2.nbt.6 Add up to four two-digit numbers using strategies based on place value and properties of operations.
2.nbt.7 Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
2.nbt.8 Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.
2.nbt.9 Explain why addition and subtraction strategies work, using place value and the properties of operations. (Note: Explanations may be supported by drawings or objects.)
measurement and datameasure and estimate lengths in standard units.2.md.1 Measure the length of an object by selecting and using appropriate
tools such as rulers, yardsticks, meter sticks, and measuring tapes.2.md.2 Measure the length of an object twice, using length units of
different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
2.md.3 Estimate lengths using units of inches, feet, centimeters, and meters.2.md.4 Measure to determine how much longer one object is than another,
expressing the length difference in terms of a standard length unit.
relate addition and subtraction to length.2.md.5 Use addition and subtraction within 100 to solve word problems
involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
2.md.6 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent whole-number sums and differences within 100 on a number line diagram.
Second Grade – Standards 1. extending understanding of base-ten notation – Students extend their
understanding of the base-ten system. This includes ideas of counting in fives, tens, and multiples of hundreds, tens, and ones, as well as number relationships involving these units, including comparing. Students understand multi-digit numbers (up to 1000) written in base-ten notation, recognizing that the digits in each place represent amounts of thousands, hundreds, tens, or ones (e.g., 853 is 8 hundreds + 5 tens + 3 ones).
2. building fluency with addition and subtraction – Students use their understanding of addition to develop fluency with addition and subtraction within 100. They solve problems within 1000 by applying their understanding of models for addition and subtraction, and they develop, discuss, and use efficient, accurate, and generalizable methods to compute sums and differences of whole numbers in base-ten notation, using their understanding of place value and the properties of operations. They select and accurately apply methods that are appropriate for the context and the numbers involved to mentally calculate sums and differences for numbers with only tens or only hundreds.
3. using standard units of measure – Students recognize the need for standard units of measure (centimeter and inch) and they use rulers and other measurement tools with the understanding that linear measure
involves iteration of units. They recognize that the smaller the unit, the more iterations they need to cover a given length.
4. describing and analyzing shapes – Students describe and analyze shapes by examining their sides and angles. Students investigate, describe, and reason about decomposing and combining shapes to make other shapes. Through building, drawing, and analyzing two- and three-dimensional shapes, students develop a foundation for understanding attributes of two- and three-dimensional shapes, students develop a foundation for understanding area, volume, congruence, similarity, and symmetry in later grades.

Work with time and money.2.md.7 Tell and write time from analog and digital clocks to the nearest five
minutes, using a.m. and p.m.2.md.8 Solve word problems involving dollar bills, quarters, dimes, nickels,
and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
represent and interpret data.2.md.9 Generate measurement data by measuring lengths of several
objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.
2.md.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put together, take-apart, and compare problems using information presented in a bar graph. (Note: See Glossary, Table 1.)
geometryreason with shapes and their attributes.2.g.1 Recognize and draw shapes having specified attributes, such as
a given number of angles or a given number of equal faces. (Note: Sizes are compared directly or visually, not compared by measuring.) Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
2.g.2 Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
2.g.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

Using High Cogni+ve Tasks
Low and High Level Tasks
• Low-‐Level Tasks – memoriza7on – procedures without connec7ons to meaning
• High-‐Level Tasks – procedures with connec7ons to meaning – doing mathema7cs
Which type of tasks are most oLen used in your classroom?
ShiLs in Classroom Prac+ce
What are the shi^s in classroom prac7ce when the CCSS content standards and Mathema+cal Prac+ces are merged? Read ShiLs in Classroom Prac+ce. Where is your math classroom on each con+nuum?

The Task Analysis Guide (Source: This table is provided verbatim from Smith & Stein, “Selecting and Creating Mathematical Tasks: From Research to Practice,” Mathematics Teaching in the Middle School, February 1998, 3(5), p. 348)
Lower Level Higher Level Memorization Task x� Involve reproducing previously learned facts, rules,
formulae, or definitions to memory.
x� Cannot be solved using procedures because a procedure does not exist or because the time frame in which the task is being completed is too short to use procedure.
x� Are not ambiguousȄsuch tasks involve exact reproduction of previously seen material and what is to be reproduced is clearly and directly stated.
x� Have no connection to the concepts or meaning that underlie the facts, rules, formulae, or definitions being learned or reproduced.
Procedures With Connections Tasks x� Focus students’ attention on the use of procedures for
the purpose of developing deeper levels of understanding of mathematical concepts and ideas.
x� Suggest pathways to follow (explicitly or implicitly) that are broad general procedures that have close connections to underlying conceptual ideas as opposed to narrow algorithms that are opaque with respect to underlying concepts.
x� Usually are represented in multiple ways (e.g., visual diagrams, manipulatives, symbols, problem situations). Require some degree of cognitive effort. Although general procedures may be followed, they cannot be followed mindlessly. Students need to engage with the conceptual ideas that underlie the procedures in order to successfully complete the task and develop understanding.
Procedures Without Connections Tasks x� Are algorithmic. Use of the procedure is either
specifically called for or its use is evident based on prior instruction, experience, or placement of the task.
x� Require limited cognition demand for successful completion. There is little ambiguity about what needs to be done and how to do it.
x� Have no connection to the concepts or meaning that underlie the procedure being used.
x� Are focused on producing correct answers rather than developing mathematical understanding.
x� Require no explanations, or explanations that focus solely on describing the procedure that was used.
Doing Mathematics Tasks x� Require complex and no algorithmic thinking (i.e.,
there is not a predictable, wellǦrehearsed approach or pathway explicitly suggested by the task, task instructions, or workedǦout example).
x� Require students to explore and understand the nature of mathematical concepts, processes, or relationships.
x� Demand selfǦmonitoring or selfǦregulation of one’s own cognitive processes.
x� Require students to access relevant knowledge and experiences and make appropriate use of them in working through her task.
x� Require students to analyze the task and actively examine task constraints that may limit possible solution strategies and solutions.
x� Require considerable cognitive effort and may involve some level of anxiety for the student due to unpredictable nature of the solution process required.

Teacher demonstrates the way in which to solve a problem and helps students in solving the problem in that way.
Discussions and classroom routines focus on student explanations that address why an answer is (or isn’t) correct.
Discussions and classroom routines focus on student explanation of how they solved a task and if it is correct.
Content presented in ways where explicit attention is given to making connections among mathematical ideas.
Content presented independent of its connections to what has been previously learned.
Teacher poses tasks and challenges students to persevere and attempt multiple approaches to solving problems.
Mathematics is presented in small chunks and help is provided so that students reach solutions quickly and without higher level thinking.

Mathematics Guidelines for Inclusion of
Measurement Conversions and Formulas
1
Conversions or formulas that are allowable with a particular item type will be given either in the item
stem or in the stimulus for a performance task.
Measurement Conversions
LIST A: The measurement conversions listed here are not included in directions for any item type at any grade level in either the Smarter Balanced summative or interim assessments.
1 foot = 12 inches
1 yard = 3 feet
1 meter = 100 centimeters
1 kilometer = 1000 meters
1 kilogram = 1000 grams
1 liter = 1000 milliliters
1 hour = 60 minutes
1 minute = 60 seconds
1 week = 7 days
LIST B: The measurement conversions listed here are given only in performance task stimuli, and not
in computer adaptive testing (CAT) items. The first grade level at which tasks are eligible for the given
conversion is listed in brackets, and the conversion is then allowable in performance tasks at subsequent grades as appropriate to the task. Item authors must still attend to the language as
written in the standards for a particular grade level (e.g., attending to limits within the standard such as expressing a larger unit in terms of a smaller unit).
1 cup = 8 fluid ounces [Grade 4]
1 mile = 5280 feet [Grade 5]
1 mile = 1760 yards [Grade 5]
1 pound = 16 ounces [Grade 4]
1 pint = 2 cups [Grade 4]
1 quart = 2 pints [Grade 4]
1 gallon = 4 quarts [Grade 4]
All measurement conversions not appearing in List A or List B may be given in CAT item stems and performance task stimuli as appropriate for a particular item or task with respect to the standards
for the item or task’s intended grade level.
Formulas
LIST C: The formulas listed here are not included for any item type at any grade level in the Smarter
Balanced summative or interim assessments.
Perimeter or area of a rectangle
Perimeter or area of a parallelogram
Perimeter or area of a trapezoid
Perimeter or area of a square
Perimeter or area of a triangle
Circumference or area of a circle
Arc length
Area of a sector of a circle
Sum of interior angles of a polygon
Measure of one interior angle of a regular polygon
28
Mathematics Guidelines for Inclusion of
Measurement Conversions and Formulas
2
Surface area of a rectangular prism
Surface area of a cube
Surface area of right pyramids with a rectangular or triangular base
Volume of a right rectangular prism
Volume of a cube
Quadratic formula
Pythagorean Theorem
LIST D: The formulas listed here are given only in performance task stimuli, and not in computer
adaptive testing items. The first grade level at which tasks are eligible for the given formula is listed in brackets.
Volume of a cone [HS1]
Volume of a sphere [HS]
Volume of a cylinder [HS]
All formulas not appearing in List C or List D may be given in CAT item stems and performance task stimuli as appropriate for a particular item or task with respect to the standards for the item or task’s
intended grade level.
Angle Measurement Facts and Ratios
LIST E: The angle measurement facts and ratios listed here are not included for any item type at any grade level in the Smarter Balanced summative or interim assessments.
Number of degrees in a circle
Sum of interior angles of a triangle
Side length ratios in a 45-45-90 triangle
Side length ratios in a 30-60-90 triangle
Trigonometric ratios for sin, cos, and tan
All angle measurement facts and ratios not appearing in List E may be given in CAT item stems and
performance task stimuli as appropriate for a particular item or task with respect to the standards for the item or task’s intended grade level.
1 Since applications of volume formulas are not considered major work in grade 8, performance tasks that measure more complex applications of such formulas are reserved for high school.
