How to Teach Maths to Your Child

You can learn loads of maths in five years and it's perfectly possible to take a child who has no number sense at age 11. The model is really simple. Work out what maths they do and don't know and teach them the stuff they don't know. It's not rocket science, right? So you can do it with everyone. But what you can't do, I don't think, or at least it would have to be a remarkable child. You're asking for 11, 12, 13 years' worth of maturation to occur in five years - that's tricky.
