If you’re a math teacher, you don’t just waste time playing math games online, you test it thoroughly for using in a lesson. By that definition, I’ve been working for the past 30 minutes or so, completing all the levels (20 so far) of Euclid: The Game.
I think I’m going to have my students play this game in one of the final lessons before the summer holidays start, when motivation usually is at an all-time low. It’s in English, but the vocabulary shouldn’t be too hard to pick up.
