Strand: Mathematical Practice Standard #2

3.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. Third grade students use reasoning to determine how to use addition and multiplication to find perimeters of shapes. 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: •

The numbers and symbols in this problem mean ___________. • The relationship between the numbers is _______. • This word problem can be represented by __________.
