Pass the Banana Phone Game
I found this game here, changed the language to reflect the textbook and fixed it up (added slides and sound files, changed images). Props to the original uploader.
Students pass the banana phones (I bought two plastic bananas from Daiso for 1000 won each) to music. When the music stops, students holding the bananas practice the dialog onscreen. Mark the bananas A and B to predetermine student roles and save time.
Please doublecheck the files before using to make sure everything works after editing on both Mac and Windows long with the *.pptx to *.ppt conversion.
