On this auspicious day—number 600—I used German in my English class. On the board I wrote: Sekunden spater klirrte eine Glocke und Malfoy betrat den Laden. I then went on to show how I only had partial knowledge of each of those ten words, but that by being exposed to them in a sentence, within context, I improved what I knew of all of them. I also demonstrated how I was okay with the overall meaning, and that the preceding and following sentences helped me further.
The students understood. One even recognized it as coming from Harry Potter!
