Research-Based Instructional Strategies (RBIS) represent the most significant shifts needed to bridge the gap between research and practice in mathematics instruction. In this extended two-day session, participants will take a deeper dive into four high-impact strategies: Balancing Conceptual and Procedural Understanding, Developing the Depth of Key Concepts, Building Coherence of Key Concepts, and Supporting Productive Struggle. Designed for educators implementing any mathematics curriculum, this session provides time to explore, analyze, and apply these strategies with greater depth. Educators will engage in rich discussions, practice-focused tasks, and collaborative reflection to support sustained changes in instruction.
