An example of one of the things I have been doing with some mid-level classes: W-H questions. They read a story (fiction or non-fiction) in our large reading book and then, in small groups/pairs, make some questions. They write their questions on the whiteboard, then everyone writes the questions down and answers them, with volunteers writing the answers on the wb. Only one of the sentences you can see is mine. The process can be time-consuming and is harder for the students than you might think, but it challenges them and is (I think) a good activity.
(The red x's you see are for speaking unnecessary Korean in class; the students get three chances, then everyone writes lines or something in their notebook at the end of class, which makes them late getting out. It's surprisingly effective, and they hardly ever have to write after the first time or two.)
