First, I wrote on the board:
What are 5 things you're an expert in?
I then filled in the blanks with my own answers: Cooking/ Canada/ Teaching English/ Scuba Diving/ Reality TV
I gave the students about 3 minutes to do the same. Then, I narrowed my list down to the 3 that I thought were the most interesting to other people and wrote them on a folded over paper that can stand up on the desk. Once the students had done the same, we all broke off into groups of 2 and had 5 minute conversations about the topics on the papers. After 5 minutes, we all switched partners.
This is a beginner (ish) class but they were all asking and answering questions in a relevant, understandable kind of way *(in English!). It made my heart feel happy.
