This is a powerpoint presentation I prepared for my conversation class (intermediate onwards). It contains some vocabulary activities, discussion questions, and a short video. The spinning wheel at the end is meant to work as a "Speak for a minute about..." activity). It took me several classes to complete the whole set of activities, as everybody had something to say!
I suggest using different types of grouping for the various activities.
My class is quite relaxed, we're pretty much the same age and we get on well, but the situations to give advice nearly at the end might not be appropriate for some groups.
