Pre-listening activities help learners to listen more effectively. Read the following pre-listening activity:

The teacher says: “You are going to listen to a conversation between a boy and his grandfather, Mr. Harris. His grandson is asking Mr. Harris what life was like in the 1940s, when Mr. Harris was a boy. Work in groups of four and together try to guess ten words which you think you will hear in this conversation. Write down the ten words in your notebook.” Learners listen to the dialogue to check how many words they guessed. (adapted from TANNER, R.; GREEN, C. Tasks for Teacher Education: a reflective approach. Essex: Longman, 1998, p. 36)
