first i agree with above poster, talk about the consquences.... she should not have recess taken away as a punishment. she has to move.

I would definatley talk to her teachers to fine tune her 504 plan. you sitting in on every class is not reasonable and not realistic. you can't do that her whole life... what happens when she gets to high school? something has to be figure out now.

i also agree with above posters that consistency is key... having concrete structure. do you know how she learns best? maybe the teaching style is not matching her learning style, and therefore she is bored and frustrated? there are many variables... but i would definately set up a meeting with her teachers.
