Mathematics Concepts and Problem Solving

Dr. Christy Mulkey discusses Competency 6 of the EC-6 math exam, covering mathematical processes, logical reasoning, and problem-solving strategies. She provides examples, including order of operations and balanced scales, and discusses teaching decimal notation using manipulatives. The video concludes with resources for further study and a brief history of geometry.
