Strand: Mathematical Practice Standard #2

2.MP.2

Reason abstractly and quantitatively. Make sense of quantities and their relationships in problem situations. Contextualize quantities and operations by using images or stories. Decontextualize a given situation and represent it symbolically. Interpret symbols as having meaning, not just as directions to carry out a procedure. Know and flexibly use different properties of operations, numbers, and geometric objects. Second grade students use quantitative reasoning as they translate the quantities in a word problem into an addition or subtraction equation. Listen and look for students that exhibit the following behaviors: • identify and understand the quantities in the problem • show and explain how quantities are related (e.g. bar diagram) • translate real-world contexts correctly to numbers, expressions, equations, or concrete or pictorial representations • connect numbers, expressions, equations, or concrete or pictorial representations back to real-world contexts

Sentence Frames: •

My (picture/equation/graph) represents the problem because _____________________ • The number _______________ represents ________________ in the problem.
