"an elementary student that has wandered into a senior classroom"
You're preaching to the choir there. Haha. I feel the same way.
This list seems interesting and it's a cool twist on word lists (which are not what you have; word lists are just lists of words; you have something different).
If I were you, I would keep expanding the list to include different things: i.e. short common sayings, place names that would be apposite, etc. I think it already has some value, but this could make it a bit more comprehensive, and less niche-y. lol.
