What's Your Range??

A little personal information first: I am very new at teaching. I don't think the first lesson I taught went over as well as I wanted to. I feel like I rushed everything but I do think the sparring game I had made up for it. People said that they really liked it. (see http://www.kihonwasa.com/2011/11/class-was-taught.html)

So for my second lesson, Shihan asked me if I would teach about 5 days before the class. I know, five days is a lot of time, but being new at this, 5 days seemed very short. I racked my brain for something that would be relevant to teach. Do I go over a basic technique and help them perfect it? Like front snap kicks, or the basic jab, cross? Do i go over something a little more fancy like a spinning jumping back kick? Do we work on something I need to work on so I can get better while helping others?
