This workshop is designed for educators seeking to create math classrooms where students actively engage in thinking and problem-solving, based on the work of Peter Liljedahl. Participants will explore the first seven aspects of Building Thinking Classrooms, including effective use of vertical non-permanent surfaces, visibly random grouping, and fostering student autonomy. Through research-based strategies and practical approaches, educators will learn how to promote deep mathematical thinking, collaboration, and active learning. By the end of the workshop, participants will have the tools and confidence to implement these strategies to enhance student engagement in mathematics.
