Overview

The last session focused on developing and justifying conjectures and analyzing and responding to students’ explanations.

This session provides an opportunity to consolidate learning about reasoning, explanation, and mathematical practices through work with one last mathematics problem. The session also provides a chance to re-engage with the idea of “scaling” and modifying mathematical tasks. The session focuses on:

• Unpacking some of the mathematics within a mathematical object known as Pascal’s Triangle
• Scaling and modifying mathematics tasks that are typically found in curriculum materials and simultaneously thinking about how to make mathematical practices more explicit within tasks
