If you can get a student to want to understand something, most of the work is done. So when I look at school, I can't believe how badly structured it is, because the idea is effectively to threaten you into learning something. That's not going to make it stick, it's not going to make you want to learn more.
So my feeling is that you want to create a desire in the student to understand the thing, then your work is pretty much done, then it's like play.
So I wonder if there's a game out there where you can learn about money in a fun way.
