The teacher edition uses manipulatives to develop the students’ knowledge of operations, whole numbers, decimals, and fractions. Teaching guides introduce and develop pre-algebra, geometry, measurement, and data skills. Teaching notes incorporate ideas for other strategies and integrating technology, while solutions for lesson problems allow teachers to easily guide students through assignments. Answer keys for student activities pages are located after solutions and teaching guides for the daily review pages. Additional instructional aids are available in the back matter.
