It also gives an argument for what is a subset. The discussion could lead into how to better represent a subset once you know some set is a subset of another.
I give a sorting problem to my preservice elem teachers that has a subset in it. It's always interesting to see who recognizes that it is subset immediately, who sees it in the middle of the problem and who never notice (or at least don't mention it).
