Making Tetrahedron Shaped Ornaments

Here's a way to combine Geometry and a Holiday Craft Activity.

  • paper
  • printer
  • crayons/colored pencils/etc. (optional)
  • scissors
  • glue

Tetrahedrons are 3D shapes made with 4 triangles.  

You can download a tetrahedron model from the Math is Fun Website. Click on the link below.


You can use white or different colors of paper to print the models.

Students can decorate the 2D Shape (also called a NET), if desired. Then they need to cut, fold, and glue their 2D paper shape to make a 3D Figure.

These Tetrahedrons can be used as colorful holiday ornaments or as decorations any time of year. They can be hung on a tree, in windows, from the ceiling, on a mobile, etc.

Math Facts about Tetrahedrons
  • 4 triangular faces (sides)
  • 6 edges
  • 4 vertices (corners)
  • also called a triangular pyramid

  Have fun with math and crafts!
