Geometry - Making a Paper Plate Icosahedron

An Icosahedron is a 3D Shape with 20 Sides!




Materials
  • 20 small plates
  • stapler
  • crayons/markers (optional)

Directions
  • Students could color or decorate the plates, if desired.


  • Next, fold each plate into a triangle.



  • Staple 2 plates together. Use 3 staples.
  • Attach 3 more plates and form a pentagon.

  • Repeat the last 2 steps with 5 more plates to make another pentagon.
  • Staple the 10 remaining plates together into a long chain.

  • Staple the ends of the chain together to form a circle.

  • Staple one pentagon to the top of the circle and the other pentagon to the bottom of the circle.


 You can now display your 3D figure on a table or hang it from the ceiling.



Math Facts

An icosahedron has:
  • 20 triangular faces (sides)
  • 12 vertices (corners) 
  • 30 edges


Here is a cool video of an icosahedron.





Have fun with geometry!
