Description: This interactive, hands-on workshop explores how teachers can facilitate rich mathematical discourse in their classrooms through evidenced-based teaching practices. Participants will engage in rich tasks and discuss how the design and implementation of these tasks promotes reasoning, mathematical argumentation, and mathematical sense-making. They will also explore how the strategic use of representations in conceptual lessons invites students to discuss, connect, question, and explain thinking. In Pk-5 participants will unpack challenging concepts such as word problem structures and strategies for developing basic fact understanding and fluency and determine how these topics can be enhanced through intentional questioning and discourse strategies. In 6-12 participants will consider the ways in which discourse influences the teaching of both mathematics content and mathematical processes, such as moving between mathematical representations in algebra and developing viable arguments in geometry. Finally, participants will examine and use questioning techniques to uncover and analyze complex student thinking and leverage students' reasoning to advance conceptual understanding.
