For more than 20 years, Lucy West has been studying mathematical classroom discourse. She believes that teachers need to understand what their students are thinking as they grapple with rich mathematical tasks and that the best way to do so is through talking and listening. In this video-rich edition of Adding Talk to the Equation: Discussions and Discovery in Mathematics, she invites teachers into real-life classrooms where all students stay in the game, stay motivated about learning, and ultimately deepen their understanding.

Designed for math teachers and coaches in grades 18, this self-study guide showcases elementary and middle school classrooms where teachers inspire even the most reluctant students to share their ideas. Through the stories of skilled teachers, West offers play-by-play commentary as they get more comfortable with new talk moves and learn to tune in and respond to students' math conversations. Although these discussions occur in math class, the strategies can be used to create a respectful, productive environment for any subject area.

This video-based resource examines the importance of creating a safe learning environment; the value of thinking, reasoning, and questioning; the role of active, accountable listening; and the necessity of giving all students a you can do this message. West also emphasizes that slowing down, even in the face of time constraints, is crucial for creating a classroom where all students feel they have something to contribute. This guide includes transcripts of the case studies, with insightful commentary from West that gives you a window into her thinking and the complexities of the work she is doing with teachers, as well as her reflections on missed opportunities.
