Not academically related at all but fun anyway...
We celebrate 3/14 as a family event every year because we have a shelter dog whose real birthday is unknown so DD insists that the day be celebrated as 'cutey pie' day his Official Birthday.
That's adorable!
My family celebrates Pi Day too! It started when my brother, in high school, convinced his math teacher to give him extra credit for memorizing digits of pi. We had a family reunion for "Pi Day of the Century" (2015)
This year I was going to cancel Pi Day on account of DS refusing to participate in math over the last week, but DH brought a pie home for lunch and made pizza for supper. DH and DS did geometry word problems over supper too. Love my geeks!
