PBS has several collections of resources to help create a sense of community in the classroom.   One collection specifically addresses teachers.  Other collections incorporate lessons, videos, and activities to help students build their social and emotional muscles.

Kids learn how to deal with bullies, as well as skills in cooperation, communication, and conflict resolution.  Other collections foster kindness, empathy, and resilience.

You can browse the collections by grade level, type of media, and subject tie-ins.

Through music, video, and classroom activities, the “Don’t Laugh at Me” (DLAM) curriculum helps sensitize children to the painful effects of harmful behaviors – ridicule, disrespect, ostracism and bullying. The curriculum addresses four key areas: expressing and managing feelings, building community, resolving conflict creatively, and celebrating diversity.

The site provides a 19-lesson curriculum, as well as the music and videos that accompany the lessons. One section of the site discusses the research and statistics that back up this approach.

This site provides resources for teachers to foster a healthy school and classroom culture by helping students develop their social and emotional skills.  There are ideas, activities and lessons learned from other teachers for helping kids to learn how to deal with their emotions, resolve conflict nonviolently, and make responsible decisions.
