I saw some great ideas online, and so I borrowed some and added my own touch. I assign 3 helpers each week...

1. The Sanitation Commissioner is responsible for helping the class to keep the room clean (note it is everyone's responsiblity to keep the room clean) The Sanitation Commissioner also helps by washing the boards.
2. Administrative Assistant - this person runs errands, takes lunch count & attendance count to the office, hands out and collects papers and helps with other chores as they come up.
3. Historian - this person keeps a record of the major activities of the week, and writes one positive thing about each student in the class. I collect the historian report at the end of the week (sometimes the class helps by offering suggestions) and we will have a written history of our class that I will type and give to each student at the end of the year as a way to remember 4th grade.
