Every once in a while I think about my old teachers and what I remember about them, mostly things they said that stuck in my head. Most often it makes me chuckle, but it also makes me think about things I can say (and how I can say them) to help my students remember them. For example, I will always remember how to negate a verb in French ("SurROUND the VERB with NE, PAS") or the relative life importance of the unit circle ("if you're stranded on a desert island, at least you can scratch your unit circle in the sand.")
"PASS the PARameter in the PARentheses". Ayuh. I think I'll put that one up on the wall.
