### Prime Time at NCTM Minneapolis

This afternoon, I’ll be presenting “Experience the Math Practices with Games and Online Tools” at the NCTM Regional Conference in Minneapolis. So if you unwittingly find yourself in the Minneapolis Convention Center at 1:30 p.m. today, please stop by.

But how cool is this? My session is #210, and today is Friday, November 13. Awesome, huh?

Wait, maybe you don’t see it:

210 = **2** × **3** × **5** × **7**

Friday, November 13 = **11**/**13**

Yeah, that’s right! The factors of my session number combined with today’s date are **the first six prime numbers**. You don’t have to be a math dork to appreciate that! (Though it doesn’t hurt.)

Why is 6 afraid of 7?

I assume it’s because 7 is a prime number, and prime numbers can be intimidating.

Thanks to Castiel from *Supernatural* for that new twist on an old classic.
