Book excerpt: Math Essentials, High School Level gives high school math teachers the tools they need to help prepare all types of students (including gifted and learning disabled) for standards-based mathematics testing. This dynamic book covers thirty key objectives found in a typical secondary mathematics curriculum, including algebraic thinking; graphs, statistics and probability; linear and quadratic functions and their properties; and geometry and measurement with applications. Each objective contains three lessons: manipulative, pictorial, and independent practice. Lessons include worksheets or patterns and answer keys, and each section ends with a practice test and answer key.
