Hey there Bill! Thanks for all the great advice! I have to admit, it wasn't an original idea. One of my fellow homeschooling mamas touched on this, and now that I'm getting back into the (not at home ) classroom, I wondered about using it. As luck would have it, I'm planning on teaching at a new magnet school for technology and the principal brought up the very same concept! Of course that started a google firestorm and I figured I should also tap into the wonderful and creative minds here. Thanks again!
