Does her school offer any sort of study hall option? or exemption from Phys ed? My DD is too young for this issue right now, but when I was in 8th grade, I started competing with an elite track club outside of school. My mom went in and spoke to the counselor about it and they got me an exemption from PE and I used an "elective" time for a study hall. Having that extra time IN school to do my homework helped a TON. Especially if they can put them later in the day so she already has most of her homework assigned for the day. The other thing is to ask if the teachers are willing to give the homework for the week up front so that your child can self-manage when she does everything.
