The book Mindstorms, by Seymour Papert, lays the philosophical groundwork for teaching mathematics through programming in LOGO, the progenitor of Scratch.  The book is freely available at the MIT website here.

Feel free to contact me with any further questions.  And please let me know if you end up trying Scratch out in your math classroom!
