What is an Icosahedron you ask? It is a shape made up of equilateral triangles with 20 sides. There are a lot of different kinds of icosahedrons. They are not all equal sided. We made one called a regular convex icosahedron. What to learn how to make a paper ball icosahedron? (The hardest part is actually learning how to spell it…)
You start with 20 circles of paper. I printed out 10 sheets of paper with 2 equal circles on it. You are welcome to use my simple template.
Once you print and cut all of the circles, then you have to start folding. You will fold the circle into an equilateral triangle.
After all of the circles are folded, you will glue five of them into a round formation. Connect the folded flaps. We use used a glue stick to stick ours together. I had my 8-year-old do all of the gluing and she did it with no trouble at all! Your kids will love definitely helping with this! After you finish the first set of five, you will repeat that step with five more pieces.
Then you will take the 10 remaining pieces and glue them into one long strip or belt. Do this by alternating the triangles pointing up and down.
This strip, once finished, will be glued into a circle.
Then the first two round pieces you made will be glued to the top and bottom of the circle you just finished.
That last section is the trickiest to stick on, so your kids may need a little help.
And all done!

Wow! I’m impressed! One that you made it look so easy to construct and two…you spelled it!

That is great! I just taught a similar lesson to my grade 7 students albeit with only a straight edge and a ruler! They start with tetrahedrons and move up from there! It is also a great time to integrate the Greek roots. I teach them the alphabet and numbers 1-20, they are just everywhere!

I love the idea of integrating the Greek Roots!!!

Can you share that lesson?

Thanks so much for sharing this idea with coloured paper! I made one with my class last year out of pipe cleaners and very long straws and the kids loved it. I think the will love this even more!

These are so fun!
We used to make these when I taught middle school. I used them for book projects and the kids added information about their books on each side to hang in the classroom — so colorful and fun!

Love that idea! Thanks for sharing!
Can you email me your circle template?
