have you looked into a kumon program? im not sure what state you live in but in Vic these are quite common about the place- they have maths, reading and english programs which you go to them (at a centre) and do-it does take time out from after school but you go to them, they have structured programs so you are not floundering around on your own! kumon focusses on the child building their confidence and learning at their own pace, and all the people i know who have gone to this have reported great improvements in their kids, i think it would be really worthwhile to check it out for your daughter.
