"Twitter Door" -Have a laminated strip for every child and they get time to update status about something they learned, liked or happened during school that day! Gets them writing and ties in something they're probably already interested in! "What would the main character post on Facebook?"
Classroom Management/ Reward Idea - pick a stick and class doesn't know who that person is until the end of the day. If that person behaved in line, listened and followed directions in class with few warnings, they get a reward. If the mystery person doesn't behave their name goes back into the container.
