This session will cover the Instructional Hierarchy and Science of Learning, including: - Depth and Coherence of Key Concepts and Procedures - Conceptual Understanding, Procedural Fluency, and Automaticity - Effective Explicit Instruction for Novice Learners - Effective Practice for Mathematical Independence Participants will explore how to think differently about mathematics and what changes could benefit the students they serve.
