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.
Finding JOY in Grade: Classroom Management: The Purple Clipboard. I wonder if this would be hard to maintain accurately all day, might work better in a middle/high school setting for periods than all day elem management. Like this idea.
dislike having long lines of students waiting for me to edit their papers, I have them put their numbered clothespins on my clipboard so that I'll know who is ready to go. This would also be great for students waiting to take AR tests!
