Students work cooperatively to develop an understanding of such geometric concepts as similarity, congruency, tessellation, and how to apply transformations. Multiple technologies are incorporated into the instruction of the lessons. Online resources are presented. Students use origami to review names and properties of polygons. They sort and classify using Multicultural Design cards.
Students test a variety of polygons to see if they tessellate by exploring angles.
They begin to determine WHY certain shapes tessellate. The create jackets and investigate properties. Students use Polydrons to construct pyramids and prisms. They explore the properties of polyhedrons and begin looking for a pattern. Students create regular polyhedrons using the Polydrons and investigate the properties of platonic solids.
