Think sheet. Have the student fill this out when they have broken a classroom rule or hurt the feelings of another student, have the student reflect on their behavior and then fix the situation. I like this because it lets them think of alternatives rather than just apologizing and moving on. It also is a communication to the parents about behavior!!
Sheet for when kids come in after play stressed about 'issues' that have happened outside. Good to keep as a record, for giving some 'cool down' time, getting all sides of the story and also allows teaching to continue uninterrupted, 'til you're ready to deal with it
