Your first grader sat for an hour and worked productivly - WoW! That's so cool. An hour a week sounds good to me for a first grader.
Try to keep the issue of educational challenge level seperate from the homework time.
It sounds like your daughter is willing to accept "afterschooling" from you, and I'd encourage you to celebrate that your child isn't getting 'MOTS' (more of the same) and design an afterschooling program for the two of you. Davidson's homeschool list is a wonderful resource and very receptive to "afterschoolers."
finding the right challenge level is very important, and one of our biggest family goals for DS10, but, if your child is willing to afterschool, then let that be the place where she gets that experience. (Do you deserve more from the school? Of course - but short of moving to Nevada, your time may be better spend with direct instructing, or setting up mentorships, than advocating within the school at this moment.) Later, when your daughter won't do afterschooling with you, or is getting frustrated with what school does offer, then you will be in a position where you have to get the school to provide that challenge level.
Best Wishes,
