We combined what we discovered in a layer book. You can find directions to make the book here. Each page, or layer, has a number on it. When you lift the flap, you find the rule for that number. I used the last page to emphasize a "Major Math Concept", which you can see in the picture. I try to drive home the relationship between factors and divisors.
The kids are actually referring to it frequently, which makes me happy!
Who else has used a tool like this for math?
