For fraction problems I recommend toast. That's not an acronym, I really do mean toasted slices of bread. Chocolate bars & cakes work well too, but if you're doing a lot of it the calories mount up!
Cutting up slices of toast to represent the fractions gives a concrete visual they can recall if they get stuck, but doesn't feel babyish.
MEP has excellent lesson plans for fractions. I think you'll find them in year 5, and also year 7 at a more brisk pace. If she likes the MEP material you could pick out material from years 7-9 to supplement her school studies, or use it in parallel. It's free, so if it doesn't prove a good fit, it's only cost you some paper & ink. Even less if you do it online or send the pdf to a kindle or ipad.
