Rigor BreakdownPart 1: Conceptual Understanding

Grades P-2



Session Objectives

4

• Understand the conceptual understanding component of rigor called for in the Standards, as defined by guiding documents

• Examine various activities that promote conceptual understanding in A Story of Units

• Compare and contrast conceptual understanding activities and analyze the impact and advantages of each

• Highlight Standards for Mathematical Practice in the conceptual understanding activities in A Story of Units

• Recognize the balance and intensity of all three components of rigor in A Story of Units



Conceptual Understanding Defined by the Instructional Shifts

5

“Teachers teach more than ‘how to get the answer’ and instead support students’ ability to access concepts from a number of perspectives so that students are able to see math as more than a set of mnemonics or discrete procedures. Students demonstrate deep conceptual understanding of core math concepts by applying them to new situations as well as writing and speaking about their understanding.”



Conceptual Understanding Defined by the Publishers’ Criteria

6

“The word ‘understand’ is used in the Standards to set explicit expectations for conceptual understanding…” (page 5)

“Materials amply feature high-quality conceptual problems and questions that can serve as fertile conversation-starters in a classroom if students are unable to answer them...” (pages 9-10)



Conceptual Understanding Defined by the Publishers’ Criteria

7

“…This includes brief conceptual problems with low computational difficulty (e.g., ‘Find a number greater than 1/5 and less than 1/4.’); brief conceptual questions (e.g., ‘If the divisor does not change and the dividend increases, what happens to the quotient?’); and problems that involve identifying correspondences across different mathematical representation of quantitative relationships.” (page 10)

A Look at the Concepts in Grade 2 – Module 3



Grade 2 – Module 3 Content

9

Understanding place value through counting units of ones, tens, and hundreds• Forming and naming units of 1, 10, and 100 by bundling

straws• Manipulating units – bundling 10 ones to get 1 ten, bundling

10 tens to get 1 hundred• Relating units – 10 tens equals 100 ones, 1000 ones equals

10 hundreds or 100 tens

Video Clip – Concrete and Pictorial Models

11

Reflections:• Compare and contrast the example with

how you develop this concept in your classroom today.• Analyze the impacts and advantages of

developing conceptual understanding using concrete and pictorial models.• Identify Standards of Mathematical

Practice.

Reflections:• Compare and contrast the example with

how you develop this concept in your classroom today.• Analyze the impacts and advantages of

developing conceptual understanding using concrete and pictorial models.• Identify Standards of Mathematical

Practice.



Mathematical Practices

14

“The Standards for Mathematical Practice describe ways in which developing student practitioners of the discipline of mathematics increasingly ought to engage with the subject matter as they grow in mathematical maturity and expertise throughout the elementary, middle and high school years.”

(CCSSM, page 8)



Concrete and Pictorial Models – Key Points

15

• Concrete materials give students an experiential understanding of concepts.

• Pictorial representations offer greater flexibility than concrete models, challenging student understanding at a deeper level while maintaining their connection to the contextual situation.

• Without the concrete or pictorial models, operations become disconnected from meaning, rendering students unable to judge when and where they apply.

Lesson Engagement – Conceptual Questioning

17

Reflections:•Where did you notice conceptual questioning

taking place?•What Mathematical Practices did you notice?• Compare and contrast Conceptual

Questioning with Concrete and Pictorial Models analyzing the impacts and advantages of each.



Conceptual Questioning – Key Points

18

• Goes beyond getting the right answer • Goes beyond Yes/No questions • Encourages recognition of subtleties and exposes

current level of student understanding• “Can you think of a case where that would not work?” • “Someone else says the answer is this. Can you prove that

they are right/wrong?”• “When we get a like unit for these two fractions, will the

like unit be bigger or smaller than the units we have?”• “Can you think of a number between 1/4 and 1/5?”

about Understanding



Writing and Speaking about Understanding

20

From the Shifts: “Deep Understanding: …. Students demonstrate deep

conceptual understanding of core math concepts by applying them to new situations as well as writing and speaking about their understanding.”



Video Clip – Writing and Speaking About Understanding

21

Reflections:• How does the speaking about

understanding seen in the video compare with what occurs in your classroom/school/district today?




22

Word ProblemJoseph has 100 stickers. Jared has 60 stickers. Jared wants to have the same number of stickers as Joseph. How many more stickers does Jared need?

Reflections:• How does the speaking about

understanding seen in the videos compare with what occurs in your classroom/school/district today?



Lesson Engagement – Writing and Speaking About Understanding

25

Reflections:• Look for evidence of the “writing and

speaking about their understanding” requirement as you complete the worksheet from G2—M3—D—L10.



Writing and Speaking About UnderstandingKey Points

26

• Speaking about understanding can occur among students debating a problem or with a teacher questioning students individually or as a group.

• Writing about understanding can occur at the board, on worksheets, on homework, or in student journals.

• Both speaking and writing are valuable ways to consolidate learning and reveal students’ current level of understanding.



Conceptual Understanding – Three Examples

27

• Concrete and pictorial models• Conceptual questioning• Writing and speaking about understanding



Key Points

28

• Conceptual understanding can be promoted in a variety of ways including use of concrete and pictorial models, conceptual questioning, as well as writing and speaking about understanding.

• A Story of Units provides frequent, rich opportunities for students to develop conceptual understanding.

• These opportunities for conceptual development are often also opportunities to nurture the Standards for Mathematical Practice.



Next Steps

29

• How can you increase students’ deep understanding of the concepts you will be covering when you return to your schools?

• What can you share with your colleagues about implementing the conceptual understanding component of rigor?



A Call for Equal Intensity and Balance

30

The Instructional Shifts:“Students are practicing and understanding. There is

more than a balance between these two things in the classroom – both are occurring with intensity. Teachers create opportunities for students to participate in ‘drills’ and make use of those skills through extended application of math concepts...”



A Call for Equal Intensity and Balance

31

The Publishers’ Criteria:“To help students meet the expectations of the

Standards, educators will need to pursue, with equal intensity, three aspects of rigor in the major work of each grade: conceptual understanding, procedural skill and fluency, and applications.” (page 5)

“Materials and tools reflect the balances in the Standards…” (page 9)
