I spent some time volunteering at an event where we were paired up with a ~5-6 year old, working with Scratch.
We had a lesson plan booklet to work from, but I found it far more effective to completely ignore it and let the child explore, and then guide the result of that exploration into a result. Seeing the sheer delight on a kid's face when you point out that with a few minor modifications, what he or she has made is in fact a playable computer game is spectacular. (and then beatboxing with them to record "background music" and sound effects is also fun ;) )
