These are classroom jobs.
Print out and laminate as you like.
Then stick students’ names on or use clothespins with students names.
Place around the classroom as you please. I usually switch jobs for the students every week, and I put these all in the same place so there is a general location where all the jobs can be seen. This way the students remember who is in charge of which job for the week. But use it as you see fit for the students you teach!
