How can we sort cubes that are all the same size?
3. Share the data
In preparation for an all class discussion, have two sets of cubes available. Record the properties students used to sort the cubes.
- What is one way your group sorted the cubes? What property did you use to sort them?
- Did anyone sort the cubes using a different property? What was it?
- Did anyone sort the cubes by kind of material? How did you group them?
Spend a few minutes talking about the properties of the three types of materials the cubes are made of: wood, plastic, and metal.
- What properties do the woods have in common? The plastics? The metals?
- How did you know that copper was a metal or PVC a plastic?
