This 'Cosmic Contributor' job chart includes 10 pre-made job squares, and five blank squares for your own additions. This is made through powerpoint and is completely editable! :)
As the picture shows, I cut each square and glued it to a ribbon. I then use clips with the kids' names to assign jobs every week.
Teacher VIP - Student to help teacher with all duties
Clip Flipper - Flips behavior clips over before next class arrives
Pencil Patrol - makes sure pencils are sharpened and ready
Postal Worker - Puts papers in mailboxes
Blank slides for your own jobs
