You mentioned your dd was distressed about the stickers the teacher is giving out. One small thing you might do is request a meeting for you and your dd with the teacher about stickers. Would your dd be willing to tell the teacher she would like to earn more stickers and ask what would be required to do that? There is a chance it could even open the door to a discussion about deeper underlying issues.

For us, so much of school success has been about building an alliance with the teacher. There's something to be said for seeking opportunities like this when the stakes are low. And what a great way for your dd to learn about self-advocating!
