I completely agree that school lunches are not helping. These are the worst in 'nutritional value' if you can even put that label near a school lunch!
I work in a school so I am there everyday and see a lot of things firsthand.
I was going over a learning program with my son today (on technology) and wondering why our schools do not use more programs such as these. My son was picking up so very much from it. I think schools need to overhaul the system completely. Ditch a lot of the useless curriculum and stop lecturing the kids about where they are going to someday NEED this useless information.
