As we know, meaningful student talk in a math classroom is an enjoyable and productive instructional practice that allows teachers to see into the mathematical thinking of their students. But how do we take this to the next level? Utilizing the book, Why Write In Math Class? This session will take a deeper dive into a variety of ways to integrate writing into your math class that will help students construct, represent, refine, connect, and reflect on mathematical ideas. We will focus on five types of writing that will build on what we know about teaching writing within a literacy classroom and developing a classroom community that supports math talk. Participants will leave with practical suggestions on how to support writing in math as well as specific examples of writing prompts that require high-cognitive demand.
