This Aztec Sun Stone project is one of my favorites! I taught it to 5th graders in Indiana and 7th graders in Honduras and now my 6th graders here in Korea have tried it out too. The students learned about the Aztec Sun Stone (they already knew a lot about the Aztec culture…yay!) and then designed their own radially symmetric design. After creating a foam printing block, they made lots of copies of their Sun Stone on fun colored paper.
