I would have a meeting with the principal and the teacher and discuss a happy medium on how much work your daughter does at home. The teacher let this go way to long and now wants to throw it at you to fix.
My daughter is in college and my son is out of college. In my experiance if you go to the teacher she will just give you a hard time ( you can try...) But when you bring in the principal they have a big attitude change real fast. I would be willing to bet they come to a reasonable amount of work for your daughter to complete at home.
