In this challenge, you will work in a group to investigate circular

Complete these two jigsaws then put one on top of the other. What

change the position of the jigsaws?
Three or four brains are usually better than one! Working on a problem in a group rather than on your own is often a good idea. These activities will help you get better at group work.
