Building Thinking Classrooms is an instructional framework designed to actively engage students in collaborative problem-solving and critical thinking. In this professional development session, we will explore how to create a learning environment that promotes movement, collaboration, and rigorous thinking on a daily basis. Participants will learn strategies to implement rich tasks that challenge students to think deeply, communicate their reasoning, and engage in meaningful discourse with their peers. This approach fosters a culture of curiosity and perseverance, empowering students to take ownership of their learning. By the end of the session, educators will walk away with practical tools and techniques to create a dynamic, thinking-centered classroom where every student is an active participant in the learning process.
