## Reflection: Rigor Solids of Revolution - Section 3: Solids of Revolution Problem Solving

The problems in this section are similar to each other by design. I want my students to work to make sense of the problems rather than falling into the tendency to do the next problem the same way they did the previous problem. To promote MP1: Making Sense of Problems, whenever a student claims to be stuck on the problems in this section, I ask them to simply tell me what's going on in the problem. What's being rotated? What is it rotating around? How is that going to looK? Is it best viewed as a composition or decomposition? Before we even start to talk about persevering and how we're going to solve the problem, I just want to make sure that we know what the problem is in the first place.
