I'd like to hear more about Math Monkey. There are lots of these franchises about, from finger maths and Kumon to Mathemagics and Magic Maths. What kinds of games are used? What makes your system better than the others (aside from fun games)?
Personally, I don't like Maths, and I can only get high scores by being very diligent about studying and practicing. Sadly, after a big exam, I tend to forget most of what I've learned so that, although I took several Maths classes in senior high school, I can barely remember algebra and geometry, let along trig and other more advanced materials.
