The fact that she’ll put these on AND have her pic taken could mean: 1) She missed @cfless & me desperately while we were @ #NCSM24 & #NCTMCHI24. 2) She actually loves math as much as we do. 3) She’s an amazing kid who will cheese it up with her dad. 4) All of the above.

I mean, this pretty much sums up my experiences at #NCSM24 and #NCTMCHI24 this week. Taking a pic with @jennalaib and @Sneffleupagus photobombs. I absolutely love this community of thinkers, Mathers, and friends.

The #wearewayne crew has showed up en masse at #NCTMCHI24! It’s always fun to see familiar faces at these conferences - especially faces of amazing educators from my own hometown. 💙

And my favorite of all: A carpet with an 84-sided shape (if I counted correctly!) called an octacontatetragon - Yes, I googled that. :)

Let’s think together: How could we figure out the total number of sides without counting?
