Look at a picture of an icosahedron on the internet first.
Cut 20 circles of paper.
Cut one thin cardboard equilateral triangle--the biggest one you can make that will just fit the circle, without hanging off the edge.
Place the triangle onto the first circle.
Bend up the extra paper on the three sides of the triangle.
These are the surfaces you will soon be gluing (or stapling) together to make the icosahedron.
Do the same thing with each of the circles.
When all 20 are ready, glue (or staple) the first two together on one side. Then add a third one. Glue them so that 5 points (5 triangles) meet. Then add the others. For the last few, you will have to use a glue stick instead of stapling.
Hint: Office Depot has a stapler that looks like a staple gun, but uses regular staples. This has excellent reach and is much easier to use for such projects.
Martha Stewart once ran an article where she made these out of used old Christmas cards.
You have to hold the edges together for a minute or two each time you glue--be patient!

How many short isosceles triangles are needed to build one great Icosahedron?
According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.

Instructions on how to make platonic solid?
There are only five geometric solids that can be made using a regular polygon and having the same number of these polygons meet at each corner. The five Platonic solids (or regular polyhedra) are the tetrahedron, cube, octahedron, dodecahedron, and icosahedron
