Phoebe's Turn at the Cotter Tens Fractal

So Phoebe made it to the spot in Level B of Right Start Mathematics where she does the Cotter Tens Fractal. This is a hands-on exercise that helps kids learn about 10's. (How many 10's are in 100? How many 10's are in 1,000? How many 100's are in 1,000?, etc.)

Here are Elizabeth's and Jonathan's Cotter Tens:

With Phillip's brilliant idea to print off the triangles instead of color and cut them out ourselves, we saved a lot of time and effort. If anyone would like to make copies of Phillip's version, feel free to email me and I'll send you a PDF or Word document. (You'd be surprised how many people have found this blog doing a search for Cotter Tens Fractal. You just don't hear a lot about that topic.)

*Edited 11/17/14: Someone emailed to request the preprinted fractals and I thought, "There's got to be a way to attach it to the blog." And of all the brilliance on the internet, there is! So here it is.
