I print this job chart on cardstock and have it laminated. Once it is laminated, I hang it (after whole punching and using a binder ring) near the calendar. I have clothespins with each child's name. I clip their name to their job that week.
I have 23 kiddos so some jobs (the bigger sections) have more than one person assigned.
I find this the easiest way to assign jobs so I can just rotate them each week.
Hope this helps :)
