Is this a teaching opportunity to bring some math into the class?


Sad to say, many highschoolers can't even manage fractions properly. I can
still hear a faint echo of "look out, the old man's teaching Physics at the
lathe again." It may seem the most natural thing in the world to give an
explanation, but in a world of magic, where the tube makes anything
possible, few are interested. Of course, probably a quarter read so poorly
that "look it up" isn't an answer, either.
