Sometimes it's very motivating for students to get a taste of fluency by mastering something very structured, yet conversational. I borrowed this 1-2-1 format from drama and here are a few examples of how I've used it recently. Students in pairs should repeat the dialogue over and over with emphasis, facial expressions, gestures and authentic intonation. The 4 x faces imply different moods that they can bring in as they work the dialogue through on a continuous loop.
