Students are organized into four color groups (red, orange, blue, and green). Use this system for grouping students in activities and for student seating at the beginning of a lesson. On the chalkboard in the gymnasium, have four laminated whistles made of construction paper colors that match the color groups. These whistles are held up by a magnet clip so that one color can be seen at a time. Every "A" day (we operate on a six day cycle) change the color of the whistle that is showing. If the color of the whistle matches a student's color group, it is that group's turn to help with equipment. Students receive two turns in a six day cycle. These students are responsible for putting away our warm-up equipment and setting it up for the next class, since the classes are sometimes scheduled back-to-back. Our warm-up uses a considerable amount of equipment organized into different buckets and a jump rope tree. Students are wonderful and they always want to help! You will find that this system works well because it allows the students to be responsible and it is a fair way of determining who my helpers are.
