For the time being I'd like to keep the programming he does related to something physical - like the lego robot you program using the mindstorms environment. At his age I think he could become bored with just shuffling bits or putting text onto a screen, and anything sophisticated enough to impress him and hold his interest (probably graphical) might be to complex. Also the challenge of physically building a controllable robot is a nice contrast to the abstract programming task. I'd like to try him with Scratch (http://scratch.mit.edu/ http://scratch.mit.edu/) before moving on to text-based programming (if he wants to). Python is a good idea: we could learn it together... I do have a netduino, and he's seem me working on that, but C# requires a lot of up-front knowledge. Arduino and wiring might be in his range. He's a bright kid and I've learned a lot just by seeing how he conceptualizes these ideas.
