My son graduated a couple years ago from a larger high school but they had a IT & Robotics program he attended that was really good. While you probably won't have as much freedom as they did when developing that specific program you might be able to get some ideas from them. The teachers and admins involved are really good people and I am sure if you reached out they would gladly send you some details. You can find some info for them here: http://www.creekaitr.com/ There is contact (email etc) on that page which would get you directly to the right people.
Good luck, I think this is awesome. I would also echo teaching a real spreadsheet class would be an awesome idea as there is so many issues you can solve using spreadsheets.
