Whole-class math project:

Today in science we are going to be working with Balls and Ramps. But today I started counting the ramps and the tubes, and I saw we had a problem! You are going to be working in 5 groups. We have 10 tubes. How many tubes can each group have?

Students go off to figure out this problem. As they finish, give them the next problem: there are 18 ramps. How will we divide them equitably between the 5 groups?

Students work individually on the problem, then come to the rug to share ideas and discuss.
