    The stacking paper lesson will be part of our linear equation unit for sure. However, I used my tangram sets with my 7th graders yesterday. We started with one whole puzzle equaling 1. So the big triangles are 1/4, the medium triangle is 1/8, and the five other pieces are 1/16. We’ve done this before so the kids understand how it all works. The test was what if the medium triangle was equal to 1. What value are the other pieces? Honestly, the kids were on task and really enjoyed it. The advantage of using concrete manipulatives is it is easy to adapt on the fly. As the students solved the initial problem I quickly changed the problem making the large triangle equal to 1. Manipulatives offer entry points for all students, that is what is so great about them.
