Here is a lesson I made for an open class about superstitions. It was the culture topic in my book. I taught it to my middle school grade 3 students. I also did a short skit with my coteacher at the beginning of the class. I asked them what superstition meant, and when they didn't know, we did the skit as a demonstration. The skit was talking about the difference between the unlucky 13th floor of a building in Western countries and the unlucky 4th floor in Korea. Most of them could say the Korean word for superstition after the skit was finished.
