How to Make a Cubic Decimeter
Preparation
 
What material will I need to make the cube?"

In my classroom we used mainly recycled materials. We did buy some masking tape, glue sticks and graph paper but the cube's surfaces were constructed from boxboard.
Boxboard
The students in my classroom supplied the class with all the boxboard for projects. I supplied the cardboard.

This is a student's recycle bag used to transport collapsed cereal boxes from their home to our classroom.
These two students' job was to organize boxboard in the classroom.
