How else might you reinforce students’ justifications of their answers?
These videos are discussed in the Inside Mathematics guide "Making Sense of Learning, 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 "making sense of learning."
