The View from Day 158: Moving into the last weeks of the school year, Mia’s students individually and collectively make use of tools and resources in their classroom to support their learning. In second grade, that looks like students’ agency and authority in the use of their tool bags, selecting appropriate resources to make their thinking visible and defend it to others.

**CONSIDER:**

How does your students’ use of and access to tools change over the course of the year?

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."
