I love colorful displays, so this crayon classroom door display "Get Ready for a COLORFUL YEAR! OUR NEW PACK" is an idea I'd love to use. This idea would also look great as a Back to School bulletin board display. Put all the kids names up to be a crayon.
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.
Great idea for creating a "peaceful" classroom community. This teacher reads the David books and The Peaceful Classroom by Naomi Drew to introduce rules and peacemaking. Then her class made this great anchor chart.
