Mathematics Implementation Module 1
Module ObjectivesModule Objectives
After today’s module on Mathematics Practice 3, teachers will have an understanding of how students should CONSTRUCT VIABLE ARGUMENTS CONSTRUCT VIABLE ARGUMENTS AND CRITIQUE THE REASONING OF AND CRITIQUE THE REASONING OF OTHERS OTHERS in the mathematics classroom (TLF 3b: Using Questioning and Discussion Techniques)

CCSS District-Wide GoalsCCSS District-Wide GoalsBy May 2013, at a minimum, teachers will be expected to:engage all students in using Mathematical Practice 3: CONSTRUCT VIABLE ARGUMENTS AND CRITIQUE THE REASONING OF OTHERS
in grade level/department groups, engage in on-going dialogues regarding FOCUSFOCUS areas for mathematics
begin reviewing current curricular materials to determine where it aligns to the critical areas of FOCUSFOCUS

The Intersection of The Intersection of Mathematical StandardsMathematical StandardsThe Standards for Mathematical Standards for Mathematical
Practice Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students.
The Standards for Mathematical Standards for Mathematical Content Content are a balanced combination of procedure and understanding. They define what students should understand and be able to do in their study of mathematics

Structure strategy: Guided sharing: Private, Partner, Public
Private: Time to think and work on the problem
Take 3 minutes to solve the problem on your own.
Partner: Time to discuss our pathways and solutions. Need for a discussion prompt: Say a Second Sentence
Ask your partner: How do you know that your answer makes sense? Tell me more.
Public: Select students to participate strategically based on work samples
Select a pair of students/participants who had different approaches.

Domain: Geometry (7th grade)
Cluster: Solve real-life and mathematical problems involving angle measure, area, surface area, and volume
Standard 6: Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

Standards for Standards for Mathematical PracticeMathematical Practice
Standard 1: Make sense of problems and persevere in solving them
Standard 2: Reason abstractly and quantitativelyStandard 3: Construct viable arguments and
critique the reasoning of othersStandard 4: Model with mathematicsStandard 5: Use appropriate tools strategicallyStandard 6: Attend to precisionStandard 7: Look for and make use of structureStandard 8: Look for and express regularity in

Activity:Do a close read of Handout 2With a partner, discuss—
What parts of MP3 do you believe you and your partner used in your discussion of the polygon problem?
What made for stronger arguments? Weaker arguments?

Mathematical Practice 3:Mathematical Practice 3:Activity:In grade level groups, using Handouts 4 and 5, discuss:
What do language standards look like and sound like for our students?
How do we share these expectations with students?
What actions should we be doing as teachers? How do we model this practice for students?
How do we begin to integrate Math Practice 3 into our lessons and classrooms now?
What commitments will we make to see this happen?

Implementation StrategyImplementation StrategyQuestioning-Putting MP3 into Practice
Say a Second Sentence
Ask students to explain how they arrived at an answer to a given math problem. Listen for student understanding not for answer-getting. Ask a student to Say a Second Sentence to explain their thinking.

“Correct answers are essential…but they’re part of the process, they’re not the product. The product is the mathematics the kids walk away with in their heads…”
