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!!
Behavior Management 4th grade+...kiddos keep a checkbook starting with a certain $ amount and pay fines for responsibilities they do not complete or other unacceptable actions...at the end of each season you can take their balance and they get to spend it on whatever they'd like :) I love it!! Teaches so many different life skills!
