Strand: Mathematical Practice Standard # 3

2.MP.3

Construct viable arguments and critique the reasoning of others. Use state 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. Second grade students solve addition and subtraction problems and make arguments to justify solutions using words, pictures and numbers. Listen and look for students that exhibit the following behaviors: • provide complete and clear explanations of my thinking and work • decide if other students’ explanations make sense; clarify or improve other students’ arguments • use counterexamples when appropriate.

Sentence Frames: •
