This lesson is awesome for health class, a school counselor presentation, a bullying seminar for students or faculty members (professional development).
A chart with the 6 stages of bullying and the thoughts, feelings, and reactions from the bully, bullied, and bystander. Information is based on the well-known book by Barbara Coloroso, the Bully, the Bullied, and the Bystander (2003).
I really like to "act" each stage out with my students. Most people / students are shocked when they realize how bullying manifests (and so quickly).
