Sometimes my students are bad. It got to the point that myself and the other EMTs had to do something. We started a behavior jar with each class. The goal was to get 25 beads in your class jar. When you behave well, you get beads in your jar. When you misbehave you get beads taken away. Simple. When you get 25 beads you get to go to the park one day for two classes.
All three classes got 25 beads so we took them to the park last week. Some classes took longer than others.
It was hot, about 41 C. But to these girls it didn't matter.
