I divide the children into 6 groups for the school year. Each group is represented by a color. There are 6 jobs and 6 groups (6 colors). I make a small poster listing the jobs. Next to the job is a piece of velcro. I attach the color cards to the velcro. The people in that color group do the job for the week. Each week the color cards are rotated so that by week 7 everyone has had a turn doing each job. My jobs are attendance and lunch count, helper, line leader and caboose, librarian, and janitor. Because the students have a week to do the job they are able to decide among themselves how they will share the job in their group. They are usually very cooperative and the teacher doesn't need to remember which individual is doing what.
