Instructions: At the next convenient opening after the given time has elapsed, insert the given phrase casually into conversation, or perform the given action.

CLASS START: Dance happily for 7 seconds.

5 minutes later: "Question: As you go through your years at Olin, from being a frosh to being a senior, or the first few years of being a faculty member, does the Olin system (whatever that means) change? Does your perspective of it change? And how do you know which changes are due to your perspective shifting and which ones are due to the system itself changing?"

10 minutes later: "Can we do a math model? Math is fun."

10 seconds later: "Yay for math!"

10 seconds later: Do the math dance.

5 minutes later: Ask everyone else what they think about something in an attempt to stall because you have absolutely no idea what to say.

10 minutes later: Draw on the board a number line with 'YAY LOTS OF MATH' on one side and 'AWW NO MATH HERE' on the other. Ask about the tradeoffs between qualitative and quantitative models. Point out that they're not mutually exclusive. "How can we tell when it's time to pull out the math, hen it's time to pull out the humanities, and when it's time to smoosh them all together in one big happy ball of fun?"

10 minutes later: Do the math dance.

That should cover the class time, I think.
