Grade 3: 4 x 7, 2 x 14 The teacher chooses to use a context as students consider the relationship between 4 x 7 and 2 x 14. How does this context help support student thinking? How is the commutative property addressed in the discussion? How do the teacher’s questions help students begin to build an understanding of doubling and halving? The teacher is continually assessing her students during the number talk. What student understanding and misconceptions will she use to guide her next instructional steps? Is there any evidence that students were engaged in the Standards for Mathematical Practice? How does what you saw in the video connect to what you read about in the progression?

D O T HESE S TUDENTS HAVE NUMBER SENSE ? How does the number line provide support for understanding Grant’s Constant Difference strategy? In what other ways could you model this strategy to help students understand why it works? The students share several subtraction strategies: Constant Difference, Adding Up, Removing in Chunks, and Adjusting One of the Numbers. Discuss how these strategies are similar and different? When Andrew shared his strategy, students were unsure whether 1 should be added or subtracted. Share your observations about the student and teacher roles during the class discussion. How could you help students understand his thinking? Is there any evidence that students were engaged in the Standards for Mathematical Practice?

What tools might students use to support to solve the problems? Discuss the strategies students might use. Might they reason with facts they know?? How might you promote the use of more efficient strategies?

M ENTAL M ATH When students solve a problem in their heads, they usually use what they know about place value, number relationships, patterns, and visual images to figure it out. Problem context Naked numbers Math & Science Collaborative at the Allegheny Intermediate Unit

How is number sense used to determine whether an answer is reasonable or not? What purpose is served by the teacher accepting both correct and incorrect answers for the problem? How is the students’ role different from typical classrooms? Often subtraction is explained as “taking away.” Cole’s strategy does not remove or take away an amount; instead, he adds to solve the problem. Why does this work? Is there any evidence that students were engaged in the Standards for Mathematical Practice? M ENTAL M ATH Math & Science Collaborative at the Allegheny Intermediate Unit

V IDEO : 8 X 25 The class had shared strategies for solving 8 x 25 before the teacher introduced the array model. Why do you think this instructional decision was made? How did she link previous strategies to this array? Noel incorrectly refers to columns as rows in the array. The teacher does not correct her. Why do you think she chose to ignore this error? How does the teacher connect the students’ additive thinking to multiplication? How does the array support student understanding of multiplication? The commutative property? The distributive property? The associative property? Is there any evidence that students were engaged in the Standards for Mathematical Practice? Math & Science Collaborative at the Allegheny Intermediate Unit

V IDEO : 150 ÷ 15, 300 ÷ 15 How did this particular sequence of problems help students use number relationships to solve the problem? What student confusions and misunderstandings surfaces from the array model? How did the teacher navigate the discussion to build understanding about multiplication, division, and the array model?
