I use this in my Fashion Design Courses to keep students accountable for cleaning up their work area and having an assigned job for each class to clean up their specific item.
I assign each student a number according to alphabetical order by their last name. This is the sewing machine number they use for the year as well as the number on the clean-up schedule.
The numbers rotate with each class period (we have block scheduling). This way no one argues about cleaning up and if a job is not completed then this is reflected in their grade for classroom management.
If a student is absent the manager for that class period must pick up the job.
