Behavior modification

Question:

I am a fifth grade teacher and I am looking for help in developing some individual behavior plans for three children in my room. One child in particular has many difficulties interacting with the other children in a positive manner. He often uses inappropriate language and can act out physically. He frequently shouts out things in class and is inconsiderate to others. He has problems where ever he goes and has been suspended for smoking on the playground.He is a nice child one on one, and will respond passively when spoken to. He just can’t seem to actually behave the way he tells you he will. Any help would be appreciated. I would like to try and help this child and desperately need to develop a plan.

Thank You
