The interaction among students determines the classroom climate: How would I like to be greeted? How do I express my anger without hurting others? Respectful behaviors and constructive conflict resolution foster a positive atmosphere in your class and prevent violence. The provided teaching materials offer ready-to-use lesson units with instructions for exercises, discussions, and creative activities. The workbook for 3rd and 4th grade includes 24 lesson units that can also be used individually, covering topics such as friendship and rules, conflicts and emotions, as well as trust and recognition.
