This is entirely user-generated content. You don’t even need to print out the sheet or give out the prompt cards. It’s basically a Task-Based lesson stewed in a Dogme-heavy sauce.
You have the learners explain and give mini presentations on different aspects of New Year. If you have international students, this will really help the others in their group as they will probably have tons of questions. They could also give differences and similarities between New Year in their countries and in Japan. Feel free to change it up, pass it on, etc. It is Creative Commons licensed.
There is a load of repetition so good chances for Task rehearsal and the tasks should be more fluent by the end. Find the sheet as a PPT and PDF in my Google Drive folder.
