Pi Day Palooza - A Collection of Ideas for Celebrating Pi Day in the Math Classroom

You may be thinking to yourself that I've lost it. It's May. Why in the world is Sarah posting about Pi Day?!? Well, this post has been on my to do list since late February. And, then you guys all know what happened in March. The world went crazy. The last day I saw my students in person was March 12th. And, Pi Day was the last thing on my mind. Instead, we spent the day speculating about this COVID-19 virus that the news couldn't stop talking about. We talked about upcoming travel plans that may or may not happen. We discussed when we might see each other again if school did have to shut down. I think a lot of us were kinda excited about the prospect of a two or three week Spring Break. Oh how wrong we were. We didn't know just how much the world was going to change. I remember realizing how it was the least celebrated Pi Day I had ever seen in all my years of being on Twitter. All this time of self-isolation has given me time to go back through my to-blog-about list and make some stuff actually happen.

I've already decided that if I get to, I'm going to go all out for Pi Day 2021. So I'm publishing this post now so it's ready to go for next March. Much like my Math-y Christmas Ideas post, this post is a compilation of Pi Day ideas that have already been shared in various volumes of Monday Must Reads. I've put all the Pi Day posts together in one spot so you can see all your options for celebrating this mathematical holiday. So, if you're a devout follower of this blog and read each and every post, there's nothing new here. Sorry. But, there's probably a post or two that you've forgotten. I know I had, and I wrote every single one of these blurbs!
