Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
A good end-of-class filler is to further discuss an idiom that came up that day: its meaning and origin. For example, an idiom that might come up in class is “under the table,” to discuss business that is not legitimate: e.g., to hire someone “under the table,” or off the record. This can lead into further discussion of cultural values and practices and more broadly, the gap between what we do and say we do that exists in to a degree in all cultures. Students can bring their own ideas about how much is “under the table” in their home as opposed to adopted countries.
Students appreciate being introduced to common idioms and the window they provide into culture.
