Paper folding can be quite fun an recently I have done a nice project with some nice techniques. The project could work quite interesting in a geometry class or in any other 3D related shapes – class.

Firstly I will share the classic instruction sheets with you and then I will show step by step how to do it:

1. Instruction sheets
2. Step by step beautiful green tutorial ^_^

Here are a couple of things you could discuss with the children:

1. What type of triangle do you get in step 4?
2. What type of center of a triangle do you get in step 9? Try to talk about the important lines in a triangle and the centers; this could be a step further or a nice piece of short revision.
3. What shape do we get in step 11? What 3D figure do we know that has faces with this shape? I believe that coming up with nice, colorful, eye-caching images would make it more interesting for the children.
4. What shape do we get in step 16? Talk about some of its properties.
5. Construct an icosahedron and discuss its properties. Make it colorful ^_^ I would talk a little about the history of the Platonic Solids and what they represented.

I had some fun making this and I thought about different ways to use the shape from step Z. Here are some fun utilities for it, feel free to make it as colorful as you want. Be creative.

Hope you enjoyed this post. I have never done something similar before so let me know if you enjoyed it. Also, if you are a teacher let me know if you use any of these. And if you are a parent have fun with your child making icosahedrons and decorate your house. If you want to do smaller versions they could look incredible at Christmas decorations.

Thank you for your help and support. You can find me on Facebook,  Tumblr,  Google+,  Twitter,  Instagram and Lettrs, I will try to post there as often as possible. Don’t forget that maths is everywhere! Enjoy!
