***Not a teacher***
I was surprised to see that only one person suggested to get the parents involved in their children's behavior. Especially when you sent homework and they didn't do it. I would write letters to the parents alerting them of their child's behavior AND request that they GET INVOLVED and help curb their unruly child's enthusiasm.
Again, I'm not a teacher but, those kids do not "become" little monsters only when they are in the classroom. If they behave that way in the classrom, they usually are like that all the time. I know, cause I was one little monster myself.
I eventually grew up and went and apologized to my teachers and told them they should have been more strict and should've gotten my mom involved.
