“The very first day, I came up with an obstacle course that everyone could do. The kids had to pick their way through five hula hoops lying on the ground; cross a mat by stepping on four giant, brightly colored "feet" that I'd cut out of felt; and then pick up an extra-large beanbag (actually a buckwheat neck and shoulder pillow) and bring it back to the group. I'd bought bags of cheap gold medals at Walmart, the kind you'd put in a little kid's birthday part goody bag. I made sure I had enough for everyone. So even when a child stepped on every single hula hoop and none of the giant feet, he or she got a medal.

A few weeks in, I noticed that Adam, a nonverbal thirteen-year-old, was always clutching that medal in whichever hand his mom wasn't holding. The medals weren't very study to begin with, and his was beginning to look a bit worse for wear, so after class I slipped a couple of spares into his mom's purse. Turning to thank me, she had tears in her eyes. "You can't imagine how much it means to him to have a medal," she said. "He sleeps with it.”
