Challenge Level

Long ago, I made a string of ten graded cubes.

Each edge of the smallest cube was one centimetre long. Each
edge of the largest cube was ten centimetres long.

I labelled each one with its volume in cubic
centimetres.

The challenge for you is to make a string of graded cubes. You
might do better working in a team, so encourage your friends to
help!

We would love to hear how you made your own cubes and to see
photos of them.

This task depends on groups working collaboratively, discussing and reasoning to agree a final product.

This task develops spatial reasoning skills. By framing and asking questions a member of the team has to find out what mathematical object they have chosen.

This challenge involves eight three-cube models made from interlocking cubes. Investigate different ways of putting the models together then compare your constructions.
