Clip 9/29: Standard 1: Making Sense and Perseverance Using Multiplication & Division Part 1A
Overview
Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution.... They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
In this clip, Mia Buljan works with her students on a number talk, using a mental math approach to multiplying a two-digit number and a one-digit number. She invites her students to share their approaches to the problem, and probes them with questions to identify rationales for their reasoning.
