Curated OER
Introduction to Polyhedra
Students investigate Euler's Formula. In this geometry lesson, students perform an inductive activity of Euler's Formula using nets to identify a variety of prism, pyramids, cylinders, and cones.

Polyhedra
Students analyze convex polyhedra through hands on methods. In this geometrical shapes lesson, students construct paper models of convex polyhedra and identify the different properties including the number of sides, faces and edges.

Investigating Nets and Polyhedra
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Polyhedra
Seventh graders explore the characteristics of three-dimensional figures. They compare the nets of figures. Students describe the relationship between the nets draw and the solid. They identify the vertices, edges and faces of the...

Pyramids & Prisms: Guler's Formula
Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...
