How many ways are there of joining three equilateral triangles together? What about four?
There are two main reasons for using this problem in the classroom. The first is to encourage children to develop a systematic approach to solving problems. The second is to enable them to understand that rotating a shape does not change the shape itself, it just puts it in a different place (or orientation). Both these ideas can be touched upon as you introduce the problem.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
