This resource presents more than 150 classroom-tested activities to help middle school students effectively handle conflict. The curriculum teaches students 20 basic conflict-resolution skill areas, including active listening, perspective taking, negotiation, and mediation. The activities are cooperatively structured and presented for three grade levels (grades 6-8). Through discussion, role-plays, and journal writing, students broaden their definition of conflict, discover how conflicts escalate, explore connections between diversity and conflict, and learn how to de-escalate conflicts. The guide also offers practical and innovative suggestions for infusion into the standard middle school curriculum. The booklet provides many handouts that can be reproduced and used as teaching tools with each chapter.
