Finding Evidence, Justifying Strategies: After the first weeks of school, Patty Ferrant’s students share their answers but ask few questions of each other.
They are then able to help peers who are “still struggling” and clarify their evidence and strategies for learning.
How do you highlight student strategies and require them to defend their reasoning?
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."
