Clip 2/12: Day 2: Presenting new tools and modeling their use

Presenting and Selecting Tools: The first week of school, Mia introduces her students to the concept of showing a “math idea” by using tools. She challenges her students first to “tell their hand” in a whisper voice what she’s trying to show with her tool. In doing so, she engages the students in identifying that the tools can be used for different purposes without telling them directly that a given tool is used for a particular purpose.
