Ren,
I would never say that kids in X range need the most help. So much depends on location, personality, and temperment. But yeah, Advocating for my 'invisiable' Level III has been a real ... growing experience.
The key piece of advice that I didn't have, was to keep feeding whatever 'burn to learn' your child shows, and to gently introduce topics you think your child might enjoy. I didn't want to insist that my kid work at home on "Mom Homework" because I didn't want to be a 'HotHouser' or percieved as one. Plus I was still in heavy gifted denial at that time.
Anyway, a book you may find useful for your afterschooling is
by Amy Burke and Nathan Levy, called "Not Just Schoolwork." I'm a 'non-linear' myself, and I remember getting ahold of one of Levy's books as a tween and thinking that finally I'm home!
At your daughter's stage, you will possibly have to translate, but that book could keep you both happily occupied for quite a while.
Best Wishes,
Grinity
