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!!
If your child has a speech or language delay, their speech therapist may suggest several strategies to help them with communication. For us, and for many, the most useful strategy has been PECS. But what are PECS and how do you get started with them?
