I am a student teacher in the 4th grade and my question is about how to get kids settled down when returning to the classroom. I bring the kids from lunch back to the room. Prior to lunch, they have had a special AND recess, so it takes a lot to get them quiet. I have tried telling them how 4th graders act as compared to 3rd graders and have a system where they get to put up a "gumball" (a sticker) on a large gumball machine cut-out. I have thought about turning out the lights as well to get their attention. Any suggestions from experienced teachers? Thanks.
