Geometry Common Core

"These middle-school level mathematics books address the skills students must master to excel on in-class and standardized tests. Aligned to Common Core standards, the math in these books is presented in short and snappy lessons that build on each other one step at a time. What's more, the lessons teach by example, promoting learning by understanding-not memorization. Most lessons are reinforced by sample questions for students to try on their own, with clear, step-by-step solutions. Each book also includes loads of valuable memory 'hooks' and shortcuts to help students retain what they are learning." -- Publisher annotation.
