Transform mathematics instruction with the comprehensive mathematical competencies (CMC) framework--a research-based model that integrates seven essential competencies: conceptual and procedural integration, problem solving, logical reasoning, communication, tool use, pattern recognition, and student engagement. Through practical classroom strategies and real-world examples, create learning environments where students build deep mathematical proficiency through meaningful, connected experiences. K-12 teachers can use this book to: (1) Implement the seven mathematical competencies through detailed curriculum, planning, instruction, and assessment strategies; (2) Move beyond isolated skill practice to develop integrated mathematical understanding and proficiency; (3) Create classroom environments that foster productive engagement and mathematical confidence; (4) Apply research-based approaches that connect conceptual understanding with procedural fluency; and (5) Design meaningful learning experiences that develop critical thinking and problem-solving abilities.
