20 questions: Students work in pairs or small groups. One student chooses an object or person and keeps it a secret. The other students must ask yes or no questions to determine what that object/person is. The maximum number of questions is 20.
Guess the card: Students work in partners. This is similar to 20 questions only the students already have the object chosen for them. One student holds a card so that their partner can’t see. The partner must then ask yes or no questions to determine what is on the card. Often teachers structure this activity to fit with the theme of a particular unit.
Find your partner: Whole class participates. Students are each given a card with an image on it; there are two of each image. Students must circulate and try to find the person with the same image by asking yes or no questions. The students may not ask “Do you have an elephant” if their image is, for example, an elephant. They must ask more descriptive questions, for example “Does your thing have 4 legs?” or “Does your thing live in the jungle?”
Words on back: Students work in large groups or as a whole class. Each student has a word attached to his or her back; the students must then circulate asking each other yes or no questions to determine what word is on their back.
Same different: Students work in pairs. Each has a different picture that should not be shown to their partner. The students take turns asking each other yes or no questions to find out how the pictures are different.
