p. 581C

Construct viable arguments and critique the reasoning of others. Use stated assumptions, definitions, and previously established results to construct arguments. Explain and justify the mathematical reasoning underlying a strategy, solution, or conjecture by using concrete referents such as objects, drawings, diagrams, and actions. Listen to or read the arguments of others, decide whether they make sense, ask useful questions to clarify or improve the arguments, and build on those arguments.

4.MP.3

Fourth grade students construct arguments to justify classifications of figures, and they critique the reasoning other students use to make geometric identifications. Listen and look for students that exhibit the following behaviors: • ask questions to understand other people’s thinking • identify mistakes in other people’s thinking • provide suggestions for improving other people’s thinking.
