Rob shares his journey from district leadership to international math coaching, his work with Innovomat, and the power of structured mathematical debate in helping students build deeper understanding.

Together, Ron and Rob dig into the heart of mathematical debate—how fostering student voice, teacher voice, and genuine curiosity leads to deeper understanding. Instead of debating to “win,” they explore how structured argumentation helps learners make sense of ideas, justify their reasoning, and consider multiple perspectives. Rob shares why reclaiming debate as a respectful, evidence-based practice can shift classroom culture and empower everyone in the learning community to think more critically and collaboratively.

They also discuss emerging issues in math education, including the role of Mathematical Practice 3 (creating viable arguments and critiquing reasoning), the integration of debate into pedagogy, and practical strategies to create equitable, high-quality math experiences for all students. Whether you’re a teacher, instructional coach, or school leader, this episode offers insights and inspiration to get students talking, reasoning, and truly making sense of mathematics.
