Navigating through Geometry in Grades 3–5 (with CD-ROM)
By M. Katherine Gavin, Louise P. Belkin, Ann Marie Spinelli, and Judy St. Marie
The "big ideas" of geometry–shape, location, transformations, and spatial visualization–are the focus of this book. Sequential activities will enrich the curriculum and help students develop a strong sense of geometric concepts and relationships, leading them to experience the joy and wonder of geometry and other mathematics. The supplemental CD-ROM features interactive electronic activities, master copies of activity pages for students, and additional readings for teachers.
