Communication activities for the classroom. In the Student's Book, students learn how to do things with English — how to persuade a friend, how to apologize, how to complain, and so on. After each function is presented, students learn to understand a variety of ways to express it and then some ways to perform it themselves. There are teacher-controlled exercises, as well as pair and small group work involving role plays, problem solving tasks, and discussions. The communication activities are particularly useful in developing conversational skills and fluency. Writing skills are also practiced in each unit.
