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.
