In my very weak and feeble attempt to explain PI to 6- (almost 7, they would immediately correct me) year-olds, I began by quickly sketching a crude picture of the Greek mathematical symbol for PI, it's value, 3.14, and its relationship to the diameter of a circle. Sorta.
Not surprisingly, it didn't take Chago very long to connect the oh-so-hazy dots I was trying to draw and figure out why today (also 3/14) was, in fact, PI Day (and also Albert Einstein's birthday, by the by).
So before they realized that I really had no inkling about that which I was purporting to assert, I offered to make apple pie to mask my ignorance, which always goes over like Christmas in my house (the pie, not my ignorance). And food is, of course, a proven diversionary tool.
So, 2 hours later, we're knee deep in warm, homeade, Granny Smith, double-crust, apple pie WITH whipped cream, and totally claiming it as a teachable moment.
Yeah, buddy. Score one for math!
