Imagine if you will, a bulletin board in a classroom in a school for students with behavior issues. Imagine the bulletin board contained several pieces of construction paper shaped like helium balloons. Imagine the balloon shapes each contained a school guideline/rule. Now imagine photos of each student, the teacher, and assistant, each holding their arm in the air, like this one:

Then imagine a piece of yarn attached to the hands in the photo and attached to a single string that tied all the balloons together.
This was a bulletin board I created one year to represent that each one of us was responsible for upholding the classroom/school rules/guidelines.
At the end of the year we each received our photo, on which everyone in class wrote something nice about the person depicted in the photo.
I don’t know if the bulletin board was helpful in insuring the students followed the rules, but it certainly looked good!
I might have a photo of it somewhere. I’ll add it to this post if I find it.
