1. Copy one handout per pair of students, and cut the handouts up into A and B.
2. Put the students into pairs with an A and B student, and distribute the handouts.
3. Focus students' attention on the instructions and get them to do part A. This involves students inserting the missing word into the questions; a, an, or any. Offer individual input where appropriate or if your class is weaker, go through the correct questions on the board when they are finished.
4. Next, with students in pairs, encourage them to ask the questions using a, an, and any along with answering using the same words plus some.
5. Monitor the students, providing language input or error correction when necessary.
6. Finally, elicit responses from some of the students and draw to their attention any appropriate vocabulary or serious language mistakes.
