Elementary School: Using Tools in Support of Mathematical Thinking

Clip 6/12: Day 3: Inviting students to compare answers and defend their thinking


Using Classroom Supports: Once students have access to tools, they can then incorporate them into their reasoning. In the early days of the year, two of Mia’s students are able to see that they have different answers and can then use their unifix cubes to defend their thinking.


How do you invite students to compare their answers, represent, and defend their thinking?
