These are cards for Classroom Jobs with descriptors of what the jobs means. I use this with 3rd grade students but can be used with grade levels 2nd-5th grade. I set up a bulletin board with average size library card packets, write each students name on a pocket and rotate the classroom jobs once a week. We review the jobs each Monday and discuss any questions. This jobs routine has gone very well each year with all of my classes. My students of all abilities are willing and excited to help out. Plus my classroom is spotless!
