My DS, who is nearly 7 and in year 2, has come home very keen to start Kumon maths - I think some of the older children have told him about it. I dont know whether it'd be a good idea or not! He likes maths puzzles and is quite good at thembut I dont know if this means he would enjoy or benefit from Kumon...also, tbh, he does quite a lot of - mostly sporty! - stuff out of schol already and waht with that and my other 2 kids to deal with I'd need to be convinced about adding an extra thing! Does anyone have experience of kumon and what did you think of it?
