While making flowcharts for independent math practice, there was a discussion about what they could do if they had nothing to do.
A student suggested we could do a crazy dance.
Mr. Finn "Well, if you start doing the crazy dance, then I'll want to do the crazy dance and so will everyone else and we won't be getting any Math done."
Cadin raised his hand. "But Mr. Finn, we'd be doing Science, looking at forces."
