To emliminate always having to write new studnets names on small pieces of paper or whatever I was using at the time, I simply numbered my students and gave them each a clothes pin. Then I chose 5 needed jobs. I wrote the titles on sentence strips and placed them in a small apple pocket chart (any pocket chart will do- small is the key). I clipped the clothes pin next to the title and then I move them each week in number order. All students not working that week are 'on vacation.' Any unused clothes pins go on top at the leaf. No more need to remember who did what last week or what about the new student.
