Sometimes a little change can help. Can they pull him out to learn Spanish or an instument? Our school did this for one student. Could he work ahead of the class on something that he already knows rather than waiting for everyone to get it? My DS went ahead of the class on his Daily Math Paper and then was able to get out his Mindware Math Book which he loves.

Teacher seems to want kids to follow the plan so they get what they need without missing important info. Is there any pretesting possibilities? Do they know he will be homeschooled next year? That might help them to loosen up the plan.

This is very hard. We are struggling with this too.
