What should I teach in youth wrestling?

Hey. Some of my friends are working for the town rec department this summer (watching kids, teaching them skills, and keeping them out of trouble). They're supposed to be teaching a wrestling segment every monday, but I'm the only one of my friends who wrestles, so I guess I'm going to be helping out. I've never worked with little kids before, and with just an hour once a week for only a few weeks, I'm not sure what I should teach them. Does anyone have any suggestions on which moves and positions I should show them (keeping in mind that they're very young)? Thanks!!
