Each topic comes with four sections. The first is a lesson to introduce the material which is a nice lesson. The Manipulative section allows the students to explore area for the shape. The questions is simply a quiz to help the student discover how much they really understand of the material. Finally there is a quiz section that has four levels. The levels are actually four ways to check student knowledge and the student is unable to move on until the correct answer is entered. I like the way this is designed and I plan to use it in my geometry class this next year.
