It's pretty tough since she is "supposed" to be doing the assigned homework.

Do you think she is bored, or just putting up a power struggle or maybe both? I was just thinking back to when my son was that age, he is 11 now. I took him to the thrift store to pick out some new books. He picked out a few large nonnfiction books, quite lengthy. I remember one was about jouranlism and world war II, quite above his comprehension, I remember thinking oh brother...

But he happily read these books out loud to me. Quite large words, but he felt challenged and happy with this.

Maybe the teacher could help you find some assignments that will engage her more. If it's a power struggle only then yes although very frustrating, try to keep calm. Maybe there has to be a consequence for not doing it. Tho if she sat there for three and half hours, might not work either. My son can be extremely stuborrn and strong willed. I find the more calm I can keep even when he is pushing all the right buttons the quicker he will turn his attitude around.

Good luck, I hope you find a way to get her to cooperate, and keep your sanity.
