To clarify, since I can't edit: This is coming from my experience as someone who has taught math to teachers getting their master's degree. It sounds mean but I wanted to emphasize that the state of early math education is not just due to poorly designed curriculum, but because there is little incentive for mathematically competent people to teach children. (Imo, of course).

The other problem in my experience (as a parent and math nerd) is that the whole math teaching area is full of people who don't know math, so coming in and having a math person teach math means you have a huge number of arguments you'd have to have.

The only way I know of is to just get after school tuition and ignore the school. This is difficult though - why do I have to do maths after school? no one else does.
