3D Shape Wrap-up

Before we move onto our new math unit, let's review the answers from last week's questions.  First, I asked you to sort the 3D shapes into groups and tell me how you sorted them.  There were many creative ways to sort the shapes.  Some of us sorted by the number of faces, some of us grouped the shapes with a vertex together.  Here are some ways to sort them:

Next, I had two 3D math problems for you to solve.  Did you come up with these shapes?

Finally, I asked if you can come up with your own challenge questions.  Here's one that your friend came up with....can you figure out what the answer is?
