Materials: connecting cubes, paper, pencil

Use 36 connecting cubes to build each of these

rectangular prisms. Each person in your group

should build a different figure.

1. Compare the prisms you built. What do
   you notice?

Ta k e turns. Use 36 cubes to build other

rectangular prisms. Ask others in your group

to build a prism just like yours. Record the

length, width, and height of each prism.

2. How many different rectangular prisms
   did your group build?


3. How can you be sure that each prism is
   different from each of the other prisms?

Work together to guess how many

connecting cubes you would need

to build each of the solid figures in

exercises 4, 5, 6, and 7. Record

your group’s guesses. Then test the

guesses by building each figure.
