The Cotter Tens Fractal
Huh? That's my first reaction when I saw this project in Elizabeth's math curriculum. It's easier if done with a group, but we had a group of two (well, four if you count the other two kids, but they were more of a hindrance than a help, I must say). Anyway, since I had no clue what this was about, I figure you may have very little clue also.
"Fractals are a new branch of mathematics only a few decades old..... The Tens Fractal, a regular fractal starts with ten small equilateral triangles arranged in the pattern of a larger equilateral triangle, the ten triangle. Ten of these ten triangles arranged in the same pattern forms the hundred triangle. And ten of the hundred triangles in the same pattern forms the thousand triangle, the Cotter Tens Fractal.
One purpose of building this fractal is to help the children visualize and experience the repeating tens structure of our number system. Another purpose is integrating mathematics and art."
Yes, there are a thousand little green triangles in there, and yes, we cut them all out. The Fractal is 6 feet tall.
