In this math lesson, learners identify, describe, and construct the five regular polyhedra. Learners are introduced to the idea of three-dimensional figures by first reviewing polygons and regular tessellations. Comparisons are made between regular tessellations and five special polyhedra, the Platonic Solids. Using nets as blueprints, learners construct the polyhedra and record the number of faces, edges, and vertices of each. Finally, they identify a relationship between the number of faces, edges, and vertices (Euler's formula).
