I copied this page onto six different colors of paper, cut them, and laminated them. I kept them clipped together and whenever my classes needed to work in groups, I passed them out to the groups of 5 students each. Each student was assigned a job (or role) and was responsible for completing it for the group. If I had an odd number of students, I would either combine Time Keeper and Information Gatherer and give one student both roles for a group of four. Or, I would split Recorder or Reporter (depending on the task) and and two students split that role for a group of 6.
