Instead of using a traditional classroom jobs chart why not try this approach? One child is selected each day to be the handy helper, they are then responsible for assisting with all classroom jobs.

At the start of the year take a handprint from each child and laminate. Then store them in a box or on a hinged ring and simply return the current helpers hand to the back and choose the new helper from the top of the pile.

Also available in ‘helpers’ eg for two students.
