Same teacher next year?

Yikes.

No-- homeschool. This kind of thing seldom improves with more exposure...



ETA: What others have noted above, too, though...

tell your DS that he won't have this teacher again in the fall, and that you are working on a better situation for him, that you know it's been hard...

and LET HIM HAVE a number of days that he can use between now and the end of school. Seriously, if it helps him, give him a way out on a limited basis. He can have six half-days, no questions asked by you, that he can use as "get out of jail free" cards, so to speak.

Would that help him?
