A student stands at the front of the class facing the blackboard. A student in the class stands up and says, Good morning (name). Who am I? . The student at the front has to guess who said it. This game encourages students to speak in a loud, expressive voice. This can be used for various greetings and statements. Make the guessing student reply to the greeting (e.g. Good morning (name).) After a couple of times, suggest that the students alter their voices. Finally, involve the teacher. You ll find that the person who usually can t identify the voices that well is the teacher.
