This book discusses research-based strategies that middle school mathematics teachers can incorporate into their classroom instruction to help students succeed. Some of these strategies are encouraging exploration and investigation using students' prior knowledge and using multiple representations to illustrate mathematical ideas, making learning relevant to real-life, cross-curricular integration, integrating culture into mathematics teaching and learning, encouraging oral and written discourse, and incorporating technology, cooperative learning, and peer tutoring. The book also introduces key aspects in successful mathematics teaching such as instructional planning, standards, assessments, student strengths, classroom management, professional development, administrative practices, and parent and community support. Implementing the strategies described in this book will allow teachers to create effective mathematics lessons that would result in engaging classroom environments and maximized student achievement outcomes.
