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.

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

These videos are discussed in the Inside Mathematics guide "Using Tools in Support of Thinking, Mia Buljan, 2nd grade," one of 10 practice-focused guides on building classroom climates for mathematical learning.

The videos document key mathematical practices observed in teacher Mia Buljan's 2nd grade classroom over the course of a school year. In the guide (available as a PDF or an iBook download), you can explore extended narratives and questions for reflection around "using tools in support of thinking."
