To encourage diversity in language usage, first teach the students some basic target structures given in several situational contexts. The Expressways series, 2nd edition, is suggested to best facilitate this. After the students have been given time to practice, have them get into groups of two or three and create a dialogue that is based on the situations they have just practiced. Encourage them to use their imagination and move away from using the text strictly as their sole source. Each member of the group must have at least 30 seconds of speaking time in the dialogue.
