Responsibility
Learning and living in a classroom community means taking on responsibilities for that community and for the school community at large. Younger students, in particular, may not always see themselves as being tied into a community yet, but nonetheless they are! Most of my students enjoy taking on responsibilities for their community. It could be something small like cleaning up the classroom at the end of the day or something large like preparing a celebration. At any rate, I believe that to become a good citizen, students must learn early that they are connected to a community and that the community has advantages to offer and can expect contributions in return.
