Engaging students in meaningful discourse in the mathematics classroom is essential not only for deep, conceptually based learning but also for providing teachers with valuable insights into their students' understanding of the mathematical content. Discussion mapping is a high-leverage, transformative tool for both instructional leaders and mathematics teachers. Leaders will learn how to use discussion maps to deliver data-informed coaching, while empowering teachers through the co-creation of coaching goals, and driving teacher growth through insightful feedback. Teachers will discover how discussion mapping empowers students by making their engagement more visible, encouraging reflection and fostering active participation and ownership of learning. The strategies shared will not only enhance teaching practices but also create a more interactive and reflective learning environment across the system, benefitting leaders, teachers and students alike.
