I wake her up with a math joke. “It’s going to be Pi Day on Friday. Just four more sleeps. Should we get a pie for dessert?”

For the less nerdy among us, Pi Day is the celebration of (nearly) everyone’s circle-based constant pi, 3.14, celebrated on March 14th, 3-14.

“I know that already, dad.” She replies sleepily, still not fully awake. Just one day after the daylight savings time switch, I can hardly blame her for being more groggy than usual.

“You should tell your teacher.” I suggest, at the same time still trying to nudge her into getting up and joining me for breakfast.

“No.”

“Yeah!” I say enthusiastically, “And you could tell her that you know the pie secret.” I am improvising here, trying to pique her interest at quarter-after-six in the morning and knowing full-well that I was fighting a losing battle. Engaging a six-year-old on any topic is like pulling teeth… an apt analogy given that six-years-olds tend to do a lot of that, too.

“What’s the secret?” She asks, only one eye open.

“Remember I told you before?” I suggest. “The secret is that that two pie are square.”

*Ba-dum-ching!* She giggles.

I’m almost certain that she doesn’t get-it-get-it, but her reaction is priceless nonetheless. I mean, sometimes she repeats this stuff in school, or on our car rides, and I know that it’s stuck in there somewhere. On rare occasions it bursts out at a perfectly timed moment and it gains the both of us some nerd-cred. My daughter does math tricks. Cool.

“What kind of pie do you like?” I ask.

“I told you already.” She insists, and rightly. She has already told me, many time before. “Blueberry.”

### fostering independence, rule 001

*be mathmagical: celebrate math culture*

Math is a foundational skill for future independence. It let’s us measure, value, weigh, and budget. It is a core skill for doing science, building things, and computing. It opens doors. It frees the mind.

So, do your daughter a favour, and teach her some math. And have fun with it by celebrating something completely nerdy that will stick with her forever.
