Thanks everyone, for your replies. It's helped me think this through. I had been pushing DD to talk with her teacher (this is what I ALWAYS have done for school issues in the past) but she hasn't yet. It turns out he has been having end-of-the-month conferences with each student and hers hasn't come up yet. We finally agreed this week that if her conference isn't assigned this week, she will ask to talk to him about the reading assignment. I will hold off on talking to the teacher unless it seems that it doesn't go well and he doesn't understand the issue. Tonight DD and I practiced what she would say (thanks for that tip!).
Hbridge hit the nail on the head- it's not the assignment itself, it's that she's set up these "rules" and somehow although she is spending far more than the 2 hours each week with her reading, she has decided that it only counts as far less. Some of you suggested that we take over timing but that's hard for many reasons (I'm still at work when she starts, she often works independently in her room, and most importantly, she argues with us when we try to arbitrate the time!)
To those who asked-- yes this is for a high school class. It seemed odd to me too- the last time she had reading logs was 3rd or 4th grade maybe?? I'm not sure the teacher's purpose, other than maybe trying to get teens to put down their phones for 120 minutes a week? The books are self-selected. Her first choice was a quick, easy read but the current one is a more thought provoking nonfiction, but one she wanted to read. The teacher does not collect these logs on a weekly basis, but is reviewing the logs at the end of month conference.
Also, I think I have found a counselor for her that specializes in teens with anxiety and OCD- hopefully will address some of the perfectionism issues!
