Every school subject has must know ideas, or essential concepts, that lie behind it. This book uses that fact to help students learn in a unique way. Most self-study guides begin a chapter with a set of goals, often leaving the starting point unclear. In Must Know Math Grade 8, however, each chapter immediately introduces students to the must know idea, or ideas, that lie behind each new math topic. As students learn these must know ideas, they are shown how to apply that knowledge to solving math problems.

Focused on the essential concepts of sixth-grade math, this accessible guide helps students develop a solid understanding of the subject quickly and painlessly. Clear explanations are accompanied by numerous examples and followed with more challenging aspects of the math. Practical exercises close each chapter and instill learners with confidence in their growing math skills.
