After I student taught, I spent a semester as a para in a kindergarten classroom. they utilized the "letter people," which consisted to blow up people with large alphabet letters on their chests. Each week, there would be a knock at the door and "B"(or some other letter) would show up to the delight of the kids. I was amazed at how they showed up punctually every monday morning at 8:30 a.m. until I saw the principal place the letter folks there one day.:lol: Anyone still use the letter people? Just curious. You can look at their official site here.
