Yes, those are the cubes.

The long term subs I've dealt with have generally been fully fledged teachers, beholden to the same standards of ability. She clearly doesn't understand the impacts of your daughter's disability and is thereby misterpretting what she sees. If this teacher is not holding to basics of FERPA, you might want to bring this up with the principal.

Do you have anything with the school on the ADHD? A 504? It would be worthwhile to find an ally in the school who can instruct this sub on the effects of ADHD in the classroom.

You say it's nearly the end of the year, but a negative 6 weeks can have long-lasting impacts on a child.
