Helping Hands! I love ours, though, because we paint their hands the 1st week of school and stamp them on white paper. I always making at least two so that I can laminate one for the Helping Hand at circle time and the other gets to go home! Helping Hands is a fantastic tool to use at home once they are used to the routine at school :)
How this teacher manages: instead of having classroom jobs, she had a boy and girl "helping hand" of the day. The two helpers were responsible for all of the classroom jobs (line leader, door holder, running errands, etc.) Just write each students' name on a cutout of a hand and hang the hands on the wall and flip the hands each day. It is such a super easy system, and it works out so that students get to be a helper about once every other week.
