I have a joke with one of my classes–every time I feel them getting off track, I ask them what my favorite 5-letter word is, and they all say “FOCUS!” And then they get back to what they were doing.
I was talking about this to another class today, and they asked me what my favorite 7-letter word is. I said “biology.” Then they asked me what my favorite 4-letter word is. I said “love.”
And there you go. Biology, focus, and love. Teaching in a nutshell 🙂
