1. Volume and Surface Area Problems

2. Minds On
Take a model cube and a model square-based pyramid and pass it around the class. Ask students to write down how they are alike and how they are different.  
Next, put the square based pyramid on top of the cube. Show it and ask how many surfaces there are. Why is it not = 11? Explore this with the class.
Do the same with: 1. A rectangular prism and a triangular prism
2. Two cylinders
