Explaining Thinking: By mid year, students are developing capacity in explaining their thinking as well as how it is changing over time

**CONSIDER:**

How do you avoid the “trap of answer-getting?”

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."
