I suspect that it is boredom and not anxiety that is causing your dd to be disruptive. She is probably yearning for creative, out of the window (oops, I mean box) kind of thinking. I was somewhat like her at school. Twice I came close to being expelled. Once for trying to dig up the school plumbing pipes and once for making my friends cover their faces in mud(I told them it had medicinal properties that would make them beautiful). I was less than 7yo and bored to death and did not realize how bad my actions were or how they would affect others. Maybe sitting down with your dd and role-playing would help figure out what is causing her to do this.
