Using Precise Language: On the first full day of school, Mia engages her students in “understanding that they have to explain themselves.” She facilitates a conversation in which elementary students explain and defend their answers, so that collectively they can find the answer they can “prove is right.”

**CONSIDER:**

What activities help your students explain and defend their answers?

These videos are discussed in the Inside Mathematics guide "Engaging in Mathematical Discourse, 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 "engaging in mathematical discourse."
