Today while visiting the Math Twittersphere, I found this great resource called Math Munch. It is a weekly digest of internet resources for math teachers (specifically middle school teachers), but it has some FABULOUS math and art resources.
This is called a Temari Ball, created by Carolyn Yackel.
Being a Math and Art fanatic, I wanted to find out more about these! Here is a YouTube video, describing how to make this traditional Japanese ball (originally they were children's toys!) and then a step by step instruction guide.
I REALLY want to learn how to make these!
