I made this for my year 7 group to help them remember their previous lesson. The idea is, they are given 9 small triangles with a question or answer on each side. They have to rebuild a large triange, matching the questions with the correct answers. There's more answers than questions. One or two are slightly specific to our lesson (e.g. some should specify northern hemisphere, for example) but you can change these. This could be adapted for any subject.
