This is a twist on your typical set of classroom jobs. At the start of each week the numbers or jobs rotate.
The main poster is hung to inform students of their weekly job. Use a wet or dry erase marker and change the jobs as the situation needs.
On each desk attach a numbered circle. These numbers tell students what job they have. Use velcro to switch the numbers among students or change the numbers monthly. Otherwise use contact paper to secure numbers and rotate the jobs on the poser.
Really the options are endless.
This works best where students are in tables, rows or groupings of 4 or 5.Each student has a job to complete throughout the day as needed.
