For small group

At least one person who can do push-ups (10 or 20 for each group member, depending on size of group).

Reward for each group member (hamburgers, food, candy, snacks)

In a small group of 5-7 people, ask for volunteers who can do 10 push-ups.

Then, ask those volunteers who can do 10 or 20 push-ups times the number of people in the group (70 total for example).

Out of those volunteers, ask the group to pick one person to do the total number of push-ups (Student A).

Have everyone form a circle and bring student A into the middle. Then show the rewards to everyone and explain the challenge below.
