I like to have the kids learn the parts of the bike and how they work together by stripping bikes for their parts, then playing a sort of bike part jeopardy once everyone has stripped a bike - for example, "hubs for $100" and I'll hold up a cone nut and have them tell me what it is; I'll also hold up a random part and have them tell me where it comes from. This seems to help some kids.
We try to be as hands-off as possible, but we do also demonstrate procedures for those who need to see it first. Every learner is different, though, and we find that we have to use many approaches during a 3 hour block of time.
