The course kit includes all the materials for the teacher and a student for teaching Geometry. Harold Jacobs, the author, is a genius. He addresses the dialectic student perfectly. The concepts come to life and are applied to real-world examples so that students will easily take what they've learned into every day circumstances. This kit includes Teacher DVDs to help explain concepts to students. They also provide relief for the parent/teacher whom may have other children or tasks needing attention.
