Idea 1) Place some answers on a O's and X's style grid. Students have to ask the correct question to be able to play a round and try to get 3 in a line.
Idea 2) Imagine you have these 4 answers on a slip of paper:
a) Yes, I do.
b) New York.
c) The day before yesterday
d) No, I haven't
You need to ask another person in a room a question so that they say one of the answers exactly on your slip of paper.
For example number 1: Do you like Pizza?
