Do These Nets form Cubes?
For each net, write your prediction on the net. Cut out the net and fold. Did it make a cube? Were your predictions correct? Sort the nets into cubes and not cubes. Write a generalization for predicting which nets make cubes.

Test your generalization on the following nets.Predict, then cut and fold.

Do These Nets form Triangular Prisms?
For each net, write your prediction on the net. Cut out the net and fold. Did it make a Triangular Prism? Were your predictions correct? Sort the nets into Triangular Prisms and not Triangular Prisms. Write a generalization for predicting which nets make Triangular Prisms.
