One more addition for the list - the Khan Academy programming tutorials - https://www.khanacademy.org/cs https://www.khanacademy.org/cs Very hands-on, kid-friendly (but good for adults too) - I'd recommend them for middle school and up. Also, there's Berkeley's Snap!, which is a browser-based version of MIT's Scratch, with some advanced additions like first class procedures. (http://snap.berkeley.edu/ http://snap.berkeley.edu/)
