The Key to curriculum is a supplemental resource to introduce or reinforce concepts from Fractions through Geometry. Each topic is comprised of a set of booklets that can be purchased as a set or as individual books. The Geometry set has eight booklets. There is also an answer key and reproducible tests available separately for most sets.
Key to Geometry offers a non-intimidating way to prepare students for formal geometry as they do step-by-step constructions.
*Students begin by drawing lines, bisecting angles, and reproducing segments using only a pencil, compass, and straightedge.
*Later they do sophisticated constructions involving more than a dozen steps and are prompted to form their own generalizations.
*When they finish, students have been introduced to 134 geometric terms and are ready to tackle formal proofs.
