I'd talk with the teacher on or, preferably, before the first day, and bring in samples of what your child is working on at home, and ask if she can have similar work during at least a portion of the class time.
Exactly - bring in the 'physical evidence' and a booklist (book report writing if possible - in her own handwriting is best) and ask for subject accelerations.
In the long run, a family can only do what it can do. You are alert and aware and caring - that has to count for something!
Best Wishes,
