Pythagoras theorem puzzles
A friend of mine was talking to me about how boring maths is to teach. He is working on trigonometry and reviewing the Pythagoras theorem. There are so many great ways to make both of these topics fun, interesting and engaging.
Anyway, fresh from the NCLANA here are a couple of ideas that can be adapted. The main idea is to use problem situations to engage learners and to get them thinking mathematically, before giving them a procedural solution.
