Oh!

1. Give the students a series of exclamations ('Oh!', 'Ah!', 'Great!', etc.), and ask them what they think has just happened to make the speaker say them. For example, 'Oh!' might mean that: She has had a surprise. or: He has just remembered something.
2. They might brainstorm their ideas orally, or write them down. If possible, record the exclamations, or say them, rather than giving them in writing; this gives the extra dimension of intonation, and makes the meaning clearer.
