The Question Game (also called 20 Questions, the Yes or No Game, or Guess what I’m thinking of) is one of the most useful (and fun!) language games I know.
It lets you practice asking and answering questions, and it makes you think about so much that you already know, both the names of things and the categories they fit into.
One person (the “thinker”) starts the game by saying, “I’m thinking of something (or someone) that (or who, if a person) is…”
The thinker then tells the other players the category they will guess from.
It can be an animal, a plant, a food, a household or classroom object, an occupation, a historical figure, a famous actor, or even a mutual friend– anything or anyone known to all the players.
(It’s not fair to choose something some players might not know!)
Then other players ask questions to see who can be first to guess what the “thinker” has in mind. Before trying to guess the exact answer, players ask questions to “narrow down” the possibilities.
The challenge is that the “thinker” must answer truthfully, but will only answer “yes” or “no” (or “sometimes,” “possibly,” etc. He or she may also give hints, if necessary.)
