Supporting Rigorous Mathematics Teaching and Learning
Selecting and Sequencing Based on Essential Understandings
Tennessee Department of Education
Elementary School Mathematics
Grade 4
Rationale
There is wide agreement regarding the value of
teachers attending to and basing their instructional
decisions on the mathematical thinking of their students
(Warfield, 2001).
By engaging in an analysis of a lesson-planning
process, teachers will have the opportunity to consider
the ways in which the process can be used to help them
plan and reflect, both individually and collectively, on
instructional activities that are based on student thinking
and understanding.

Session Goals
Participants will learn about:
• goal-setting and the relationship of goals to the CCSS and essential understandings;
• essential understandings as they relate to selecting
and sequencing student work;
• Accountable Talk® moves related to essential understandings; and
• prompts that problematize or “hook” students during the Share, Discuss, and Analyze phase of the lesson.
Accountable Talk is a registered trademark of the University of Pittsburgh.
“The effectiveness of a lesson depends
significantly on the care with which the
lesson plan is prepared.”
Brahier, 2000
“During the planning phase, teachers make
decisions that affect instruction dramatically.
They decide what to teach, how they are going
to teach, how to organize the classroom, what
routines to use, and how to adapt instruction for
individuals.”
Fennema & Franke, 1992, p. 156

Contextualizing Our Work Together
• Imagine that you are working with a group of students who have the following understanding of the concepts.
• 70% of the students need to make sense of what it means to have a fraction as a sum of a parts of . (4.NF.B3)
At this stage in student learning, the teacher is not as concerned that students are precise. S/he will take note of who is and who is not. The teacher, however, will be precise with his/her revoicing of student contributions. (MP6)
All of the students can benefit from modeling with fractions. (MP4) Students will discuss the structure of mathematics related to the meaning
of the numerator. (MP7) 20% of the students need additional work on fraction standards
previously addressed (3.NF standards). These students also need opportunities to struggle with and make sense of the problem. (MP1)
• 5% of the students still do not recognize the importance of knowing what the “whole” is when talking about fractions. (Part of 4.NF.A2)
• The teacher will emphasize repeated reasoning when students find common denominators for each fraction. (MP8)
The CCSS for Mathematics: Grade 4
Number and Operations – Fractions 4.NF
Extend understanding of fraction equivalence and ordering.
4.NF.A.1 Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
Common Core State Standards, 2010, p. 30, NGA Center/CCSSO
The CCSS for Mathematics: Grade 4
Number and Operations – Fractions 4.NF
Understand decimal notation for fractions, and compare decimal fractions.
4.NF.C.5 Express a fraction with denominator 10 as an equivalent fraction withdenominator 100, and use this technique to add two fractions withrespective denominators 10 and 100. For example, express 3/10 as30/100, and add 3/10 + 4/100 = 34/100.
4.NF.C.6 Use decimal notation for fractions with denominators 10 or 100. Forexample, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
4.NF.C.7 Compare two decimals to hundredths by reasoning about their size.Recognize that comparisons are valid only when the two decimalsrefer to the same whole. Record the results of comparisons with thesymbols >, =, or <, and justify the conclusions, e.g., by using a visualmodel.

Essential UnderstandingEqual Size PiecesA fraction describes the division of a whole or unit (region, set, segment) into equal parts. A fraction is relative to the size of the whole or unit.
Meaning of the DenominatorThe larger the name of the denominator, the smaller the size of the piece.
Use of BenchmarksComparison to known benchmark quantities can help students determine the relative size of a fractional piece because the benchmark quantity can clearly be seen as smaller or larger than the piece. One significant benchmark quantity is one-half.EquivalencyA fraction can be named in more than one way and the fractions will be equivalent as long as the same portion of the set or area of the figure is represented.Creating Equivalent Fractions When the denominator is multiplied or divided then the numerator is automatically divided into the same number of pieces because it is a subcomponent of the denominator.

Academic Rigor In a Thinking Curriculum
A teacher must always be assessing and advancing
student learning.
A lesson is academically rigorous if student learning related to the essential understanding is advanced in the lesson.
Accountable Talk discussion is the means by which teachers can find out what students know or do not know and advance them to the goals of the lesson.
36© 2013 UNIVERSITY OF PITTSBURGH
Accountable Talk Discussions
Recall what you know about the Accountable Talk features and indicators. In order to recall what you know:
• Study the chart with the Accountable Talk moves. You are already familiar with the Accountable Talk moves that can be used to Ensure Purposeful, Coherent, and Productive Group Discussion.
• Study the Accountable Talk moves associated with creating accountability to:
the learning community;
knowledge; and
rigorous thinking.
37© 2013 UNIVERSITY OF PITTSBURGH
Accountable Talk Features and Indicators
Accountability to the Learning Community• Active participation in classroom talk.• Listen attentively.• Elaborate and build on each others’ ideas.• Work to clarify or expand a proposition.
Accountability to Knowledge• Specific and accurate knowledge.• Appropriate evidence for claims and arguments.• Commitment to getting it right.
Accountability to Rigorous Thinking• Synthesize several sources of information.• Construct explanations and test understanding of concepts.• Formulate conjectures and hypotheses.• Employ generally accepted standards of reasoning.• Challenge the quality of evidence and reasoning.

Accountable Talk Moves
Function Example
To Ensure Purposeful, Coherent, and Productive Group Discussion
Marking Direct attention to the value and importance of a student’s contribution.
That’s an important point. One factor tells use the number of groups and the other factor tells us how many items in the group.
Challenging Redirect a question back to the students or use students’ contributions as a source for further challenge or query.
Let me challenge you: Is that always true?
Revoicing Align a student’s explanation with content or connect two or more contributions with the goal of advancing the discussion of the content.
S: 4 + 4 + 4.
You said three groups of four.
Recapping Make public in a concise, coherent form, the group’s achievement at creating a shared understanding of the phenomenon under discussion.
Let me put these ideas all together.What have we discovered?
To Support Accountability to Community
Keeping the Channels Open
Ensure that students can hear each other, and remind them that they must hear what others have said.
Say that again and louder.Can someone repeat what was just said?
Keeping Everyone Together
Ensure that everyone not only heard, but also understood, what a speaker said.
Can someone add on to what was said?Did everyone hear that?
Linking Contributions
Make explicit the relationship between a new contribution and what has gone before.
Does anyone have a similar idea?Do you agree or disagree with what was said?Your idea sounds similar to his idea.
Verifying and Clarifying
Revoice a student’s contribution, thereby helping both speakers and listeners to engage more profitably in the conversation.
So are you saying..?Can you say more? Who understood what was said?
© 2013 UNIVERSITY OF PITTSBURGH 39
To Support Accountability to Knowledge
Pressing for Accuracy
Hold students accountable for the accuracy, credibility, and clarity of their contributions.
Why does that happen?Someone give me the term for that.
Building on Prior Knowledge
Tie a current contribution back to knowledge accumulated by the class at a previous time.
What have we learned in the past that links with this?
To Support Accountability toRigorous Thinking
Pressing for Reasoning
Elicit evidence to establish what contribution a student’s utterance is intended to make within the group’s larger enterprise.
Say why this works.What does this mean?Who can make a claim and then tell us what their claim means?
Expanding Reasoning
Open up extra time and space in the conversation for student reasoning.
Does the idea work if I change the context? Use bigger numbers?
Accountable Talk Moves (continued)
40© 2013 UNIVERSITY OF PITTSBURGH
The Share, Discuss, and Analyze Phase of the Lesson: Planning a Discussion (Small Group Discussion)
• From the list of potential EUs and its related student work, each group will select an essential understanding to focus their discussion.
• Identify a teacher in the group who will be in charge of leading a discussion with the group after the Accountable Talk moves related to the EU have been written.
Write a set of Accountable Talk moves on chart paper so it is public to your group for the next stage in the process.
41© 2013 UNIVERSITY OF PITTSBURGH
An Example: Accountable Talk Discussion The Focus Essential Understanding
Creating Equivalent Fractions When the denominator is multiplied or divided then the numerator is automatically divided into the same number of pieces because it is a subcomponent of the denominator.Group A Group B
• Explain your set of equivalencies.• Who understood what he said about the 100 and the 10? (Community)• Can you say back what he said how the model shows ? (Community)• Who can add on and talk about the 3 and the 30? (Community)• The denominator tells the number of equal parts in the whole. (Marking) • Do we see in both pieces of work? (Rigor) • Tell us how you found in your picture (Group A). (Rigor)
42© 2013 UNIVERSITY OF PITTSBURGH
Problematize the Accountable Talk Discussion(Whole Group Discussion)
Using the list of essential understandings identified earlier, write Accountable Talk discussion questions to elicit from students a discussion of the mathematics.
Begin the discussion with a “hook” to get student attention focused on an aspect of the mathematics.
Type of Hook Example of a Hook
Compare and Contrast
Compare the half that has two equal pieces with the figure that has three pieces.
Insert a Claim and Ask if it is True
Three equal pieces of the six that are on one side of the figure show half of the figure. If I move the three pieces to different places in the whole, is half of the figure still shaded?
ChallengeYou said two pieces are needed to create halves. How can this be half; it has three pieces?
A Counter-ExampleIf this figure shows halves (a figure showing three sixths), tell me about this figure (a figure showing three sixths but the sixths are not equal pieces).
43© 2013 UNIVERSITY OF PITTSBURGH
An Example: Accountable Talk Discussion The Focus Essential Understanding Creating Equivalent Fractions When the denominator is multiplied or divided then the numerator is automatically divided into the same number of pieces because it is a subcomponent of the denominator.Group A Group B
• Both groups say that is equal to . How can this be when the fractions use different numbers? (Hook)
• Can Group B explain why = = ?• Who understood what they said about the denominators? (Community)• Can you say back what they said about the numerator changing?
(Community)• Each group made statements about equivalency. How does the visual
model differ from/support the symbolic model? (Rigor)

Revisiting Your Accountable Talk Prompts with an Eye Toward Problematizing
Revisit your Accountable Talk prompts.
Have you problematized the mathematics so as to draw students’ attention to the mathematical goal of the lesson?
• If you have already problematized the work, then underline the prompt in red.
• If you have not problematized the lesson, do so now. Write your problematizing prompt in red at the bottom and indicate where you would insert it in the set of prompts.
We will be doing a Gallery Walk after we role-play.

Role-Play Our Accountable Talk Discussion
• You will have 15 minutes to role-play the discussion of one essential understanding.
• Identify one observer in the group. The observer will keep track of the discussion moves used in the lesson.
• The teacher will engage you in a discussion. (Note: You are well-behaved students.)
The goals for the lesson are:
to engage all students in the group in developing an understanding of the EU; and
to gather evidence of student understanding based on what the student shares during the discussion.
46© 2013 UNIVERSITY OF PITTSBURGH
Reflecting on the Role-Play: The Accountable Talk Discussion
• The observer has 2 minutes to share observations related to the lessons. The observations should be shared as “noticings.”
• Others in the group have 1 minute to share their “noticings.”
