Geometry Nets - Tetrahedron

A tetrahedron is a three dimensional shape with four triangular sides. It is a type of pyramid.

In this case, I've created a regular tetrahedron -- it is made up of identical equilateral triangles.

Explore the tetrahedron by cutting out the geometry net, folding it and gluing the tabs.

Tetrahedron - Plain: you can trace this onto decorative paper or decorate it as you see fit

Tetrahedron - cute faces: (color) or (B&W)

Holiday Tetrahedrons:

Tetrahedron - Christmas:	(color) or (B&W)
Tetrahedron - Valentine's Day:	(color) or (B&W)

Tetrahedron characteristics:

a platonic solid (a three dimensional shape made up of identical two dimensional shapes with the same number meeting at every vertex)
3 triangles meet at each vertex (or corner)
4 Faces
4 Vertices
6 Edges

Tetrahedron formulas: These are too complicated for most children. The shape is interesting because it is a platonic solid (a three dimensional shape made up of identical two dimensional shapes with the same number meeting at every vertex) I would skip the formulas for it but here they are in case you feel differently.

Surface Area of a regular Tetrahedron = where a is the length of an edge
