Jeff, I really like this idea. I tend to want to do it all perfectly the first time, and then when it doesn't work, I give up. And I, too, felt that I just didn't have the time. But now I am seeing how it will actually cut my teaching time down, because THEY will be the ones teaching. So although, it may take more time at first, writing down where I want to do teach-okay, but I think it will be so much easier once I've had some practice.
I'm also keeping my little cheat sheet of the 5-step lesson template handy while I'm teaching.
I've even written notes to myself on my whiteboard so I know what to do next - all in the pretext of letting them know what we're doing next!
