When the bell rings and the children come in after I meet them at the door, they have work to do. I put a quiz, problem or a review of some work on the chalk board. This is called "Bell Work." The children have a "bell work book" that they complete the work in. They date the page and begin the work as soon as they enter class. This gives me time to do all the administrative jobs that I need to do first thing in the morning. The work is collected and I mark it or I assign someone to mark it. It prevents many disruptions and lets the children realize that they come to class to work.
