Cylinder Cutting
Age 7 to 11
Challenge Level
An activity for high-attaining learners which involves making a new cylinder from a cardboard tube.
Sponge Sections
Age 7 to 11
Challenge Level
You have been given three shapes made out of sponge: a sphere, a cylinder and a cone. Your challenge is to find out how to cut them to make different shapes for printing.
Which Solid?

Volume of a Pyramid and a Cone
Age 11 to 14
These formulae are often quoted, but rarely proved. In this article, we derive the formulae for the volumes of a square-based pyramid and a cone, using relatively simple mathematical concepts.
Efficient Cutting
Age 11 to 14
Challenge Level
Use a single sheet of A4 paper and make a cylinder having the greatest possible volume. The cylinder must be closed off by a circle at each end.
Make Your Own Pencil Case
Age 11 to 14
Challenge Level
What shape would fit your pens and pencils best? How can you make it?
Paint Rollers for Frieze Patterns.
Age 11 to 16
Proofs that there are only seven frieze patterns involve complicated group theory. The symmetries of a cylinder provide an easier approach.
