Interviews

http://www.visual-idioms.com/

Based on my experience, most students love being recorded, even though they don't admit it. Ask your students to make mini-interviews and record them. This can't be done in the class because it would be too noisy; set it as their homework assignment. An easy way of doing so is via Audacity (a free open source digital audio editor and recording computer software application, available for Windows, Mac OS X, Linux and other operating systems). Give the students one picture with the idiom and tell them they're going to make interviews with their partners. They can use questions from the posts http://visualidioms.blogspot.com/ but they can also create their own. They send you the recordings as MP3 files. You can collect the most common errors and comment on them in the class or you can play the recording in the lesson and ask the students to give feedback themselves.
