New At Mindstorm

I recently agreed to help middle-school kids with Mindstorm and Robolab in after school activities. My only knowledge of the subject comes from the User's guide for Robolab Software. Are there any other good sources for info on programming? I've looked at the context help for several dozen icons, but I don't see how to fit them together to perform one or more tasks. Also, once the program is written, how can you print it out as text? All help would be appreciated, and thanks in advance.
