I guarantee he was embarrassed this morning.
Is there an area where he can be away from the younger kids? Mixed age groups are often blamed, but I don't always agree with that as long as he has a chance to act his own age.
Where was the teacher? I am assuming there was a steady escalation before your son snapped. Kids often yell, say no, stop, etc before resorting to violence.
I would reward for good behavior at the end of the day (watching a show before dinner, going to the playground, etc) AND at that age I would remove something for poor behavior- losing tv time, playground, etc.
also- thank you for trying to support his teacher! That means the WORLD to us!
