Understanding and Reading Problems: Teacher Patty Ferrant asks students to show a thumb signal to indicate what they know and 100% understand. Her student Chloe shares her answer, and Patty uses her response to invite other students to identify whether they agree with her, disagree with her, or are not yet sure either way.

**CONSIDER:**

What does Patty likely already know about Chloe as a learner to support her in this early sharing of her thinking?

These videos are discussed in the Inside Mathematics guide "Making Sense of One’s Own and Others’ Learning, Patty Ferrant, 8th Grade," one of 10 practice-focused guides on building classroom climates for mathematical learning.

The videos document key mathematical practices observed in teacher Patty Ferrant's 8th-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 one’s own and others’ learning."
