The Discipline Without Stress, Punishments or Rewards program By: Dr. Marvin Marshall is a great behavior system to use in classrooms from Elementary to High School. The program teaches kids to make good decisions based on what is right, not rewards or punishments. It is also great for parents to use at home with their children. Here is a set of posters for the wall that remind children of the behavior levels. There are icons that explain each of the behavior levels with example behaviors for each level. Enjoy!!
