This website would be a great activity for students in a Geometry class to learn about the faces and vertices of 3 dimensional figures as well as how the area and volume are calculated.
This website was a great resource to help prepare a student that I tutored for the SAT. It helped raise her SAT scores and qualify her for scholarships that she would not have received otherwise. It is sorted by category and explains each topic clearly in a well-organized manner and could be a good resource for more than just the SAT.
