For the unfamiliar...

Duck, Duck, Goose is a traditional children's game often first learned in preschool or kindergarten. The game may be later adapted on the playground for early elementary students.

One person is "it" and walks around the outside of the circle. As they walk around, they tap the player's heads and say whether they are a "duck" or a "goose". Once someone is the "goose" they get up and try to chase "it" around the circle.
