The Chuck-a-Duck tournament is run like a chuck-a-puck contest at a hockey game. At a given time, students toss their rubber duckie in attempt to come closest to the bulls-eye in the center of the gym. We charged $2 per duck toss. The ducks were numbered, and students registered their names next to a numbered sheet and when all were finished tossing, we measured the distances. They could purchase their own duck for $5 and write their name on the duck.
