Pinning for friends in the superhero theme. Will hang up work once school starts. But for the opening of school, I changed the words to, "Our class is.INCREDIBLE" and had my students' names posted on the bulletin board.
Here is another bulletin board in our school lunchroom. We "caught" kids drinking their milk at lunch time. I asked for participation from the teachers to stage a milk mustache picture. I still have a few spots left for more pictures!
