This would make a great procedure (Harry Wong). Count to five or hold up one finger at a time when the class needs to refocus. Discuss what occurs for each number at the beginning of the school year and eventually the reaction will be automatic.
I thought that this was a unique way to organize assignments that are turned in along with what needs to be copied and filed. Not only is it super creative but it also keeps your desk from becoming a black hole of papers that I have seen while volunteering in an elementary school classroom. ~Laura Wilson
