I kind of feel like most students will automatically default to a 1 A, 2 B, etc. table, with perhaps a few exceptions in between. Maybe that's all we should be expecting. If we are supposed to expect more, however, it would be helpful to see other examples of "model" work. I'm all for the "openendedness" of this lesson, but not having the experience of having taught this lesson before, I find myself challenged imagining what the possibilities might be. Having something more to reference (aside from other standardized character sets) would be helpful.
