Finding Evidence and Justifying Strategies: By the middle of the year, students have developed confidence in explaining their own thinking and use academic language and tools to show their thinking to others. Mia’s students use their understanding of structure to explain their thinking and defend their strategies. She challenges students to show their thinking using available tools.
How do students develop different ways of showing and describing quantities?
These videos are discussed in the Inside Mathematics guide "Making Sense of Learning, 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 "making sense of learning."
