This went down a treat, if I do say so myself. I had the principal taking part in the class as though she were a student! The dialogue was just right for the very high level of the class, so I'd change it for lower levels.
It's pretty easy to do. It's all repetition and memory but in a competitive way. I have them say the full dialogue twice, and then i start clicking the slides. They have to say the entire dialogue for each slide, so that by the time it gets to the end and there aren't any words, they've got it down. The saying it alone thing it tough for this one, even I needed prompts, but it's a good challenge. I also had them do it boys vs girls, which was fun.
