I have a student right now that completely shuts down when he is in trouble. The other day he was sent back to his seat for inappropriate carpet behavior, and he refused to speak, move, or acknowledge anyone's existence for the last 25 minutes of the school day- he wouldn't get up and put on his jacket to go outside, missed recess, and his father had to go to my classroom and physically carry him out because he refused to move to pack up and go home and I'm not allowed to touch him. This is an extremely rare occurrence in my classroom, fortunately, but Mom says it's common at home and not getting any better. She's at her wits end and looking for advice. Any ideas on how to help her deal with what she calls "the most stubborn child in the world?" I really want to give her something to hold onto to get her through this, and set him up for success in kindergarten- where I'm sure he will inevitably be reprimanded more often than he is in my classroom.
