This 2-page printable includes clear, student-friendly job descriptions for cooperative group work: Leader, Reporter, Recorder, and Materials Manager, plus two optional add-on roles (Problem Solver and Time Keeper) for larger groups.
These roles transformed group work in my classroom by increasing participation, accountability, and on-task behavior—while taking a huge load off my plate during instruction and work time. Simply assign (or rotate) roles during group activities so students know exactly what they’re responsible for, the room runs itself, and you never work harder than your students.
