Product Description

This is a great way to introduce a unit on circles to Geometry students.

The lesson is made up of two parts:

· A vocabulary review: Students fold 6 circles and review basic terms as they complete a vocabulary page.

· Folding a Circle: Students continue to review other terms as they fold a circle into a truncated tetrahedron. First students fold the circle into an equilateral triangle. Then students fold the equilateral triangle into a tetrahedron. Then finally students fold the tetrahedron into a truncated tetrahedron. If twenty truncated tetrahedrons are arranged together an icosahedron is formed.

In the lesson students will also think about Euler’s Formula for Polyhedron when a three-dimensional figure is formed in the folding. Each time they form a new three-dimensional figure, students confirm that the their discovered formula shows the relationship between the number of faces, edges, and vertices on the polyhedron.
