A Classroom Chores Planner

Divide the class into groups of five, if it is possible. Assign a name to each group. Display a monthly planner on the board. Label each week in the month: week 1, week 2, etc. Ask "Which group is going to do the classroom chores for (week 1)?"
Students choose a group. Ask students to come to the board and write the names of the people responsible for keeping the classroom tidy in week 1.
Continue with the rest of the month. If the class is large, you may need to use two monthly planners so that all the groups are assigned a week. Once all the assignments have been made, ask students questions. Point to one of the weeks and ask Who's going to (tidy the classroom) on Monday? Students respond.
