Second Grade Attempt at Behavior Modification

Our second grade teacher kept two plastic cups on the window sill. One was for the boys and the other for the girls. At the end of the day, if us boys were good, we got a marble. If the girls were good, then they got a marble. Once the cup was full, the boys or girls got a prize. As you might suspect, this never worked out well for us boys. Year-end-score: Girls 8, Boys 1.
