To assist with encouraging responsibility to students, these classroom job cards can help to also maintain a strong classroom management system.
I usually cut these cards out, and put them in my pocket chart. The pocket chart has class numbers on them, and I rotate the cards every Monday.
Attached, you will also find the job descriptions. I cut these out, and pasted them on the back of the appropriate card. If students forget what is expected of them, they can refer to the back of the card. It also comes in handy when I have a substitute teacher!
