Welcome! Your DS sounds delightful. I'm sorry you're having so many troubles with the teacher. It seems to me that she is doing an awful lot of nothing to help out your DS. I guess I would suggest contacting the enrichment teacher and asking for advice. Express all the concerns you list here. At our school, the gifted coordinator was able to act as a liaison between us and the principal, who was then able to hand-pick a teacher who would be a good fit. The enrichment teacher hopefully will be able to help with your current teacher too, but suggesting substitutions for the too-easy schoolwork. Good luck!
