Make A Rules of Divisibility Flip Book

     It's time to learn the Rules of Divisibility as part of our study of factoring! We factored all of the numbers from 1-100. We discovered what makes a number prime or composite. 

     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?
