Geometry
Classroom-ready yet scaffolded for independent study, this full-year course eliminates a common source of frustration by focusing on intuitive reasoning and active problem-solving rather than formal proof-writing. Across 8 comprehensive units, students discover not just what to do, but why it works. With detailed solutions and 8 page-mapped unit tests, this book make it easy to track mastery and identify concepts that need review.
