Pi Day, March 14, celebrates the irrational constant Pi. In the world of circles, Pi is the ratio of the diameter to the circumference; no matter the size of the circle, that ratio is always 3.14. Because Pi is one letter off from and is a homonym of “pie,” the day often includes many food and puns. Aside from eating pie, decking out for the day is a great way to celebrate.

Are you a math nerd or a teacher that needs ideas for dressing out for March 14th? Is there someone you know that you’d love to gift the joy of 3.14? We’ve scoured Etsy and have you covered!

Any Star Wars fans that are also math geeks? This shirt by BLCStore plays on the meme “Come to the Dark Side, we have cookies.” This shirt advertises the Math Side, featuring an opening sequence scroll consisting of six lines of Pi’s digits. Why? Because we have pie!

Moving away from the flashy and in-your-face shirts, how about a very low-key pin? This adorable pin from JimClift is just a little smaller than a quarter and comes in three metal colors: gold, silver, and copper. There are matching earrings for the gold and silver, too! A simple symbol for those unable to go all out for the day.

Speaking of earrings, how about a punny pair of Cherry Pi dangles? These acrylic earrings from FabUnlimitedDesigns come in a vast array of colors. They are versatile enough to be flashy for the Ms. Frizzles out there but might be just downplayed enough for the office. They’re practically perfect for everyone!

Pi Pencils

Teachers are always short on pencils, right? Why not stock the classroom with the digits of Pi? Ok, sure, these would be best in a math classroom. And some teachers may consider them cheating. But think of the learning opportunity! These pencils, offered from Wacodis, have it listed to 96 digits on each pencil. They come in convenient 6-packs or 30-packs, great for one person or one classroom!

Sweet as Apple Pi

Since we’re on the subject of teachers, why not make some Apple Pi cookies for your little one’s teacher? Or for a celebration at your office? You’ll need to find a recipe that holds up with a cookie cutter (like a sugar cookie recipe) but with an apple pie flavor boost! SignalsFromSpace has a beautiful custom printed cookie cutter just for the job! It creates a little apple cutout cookie with a symbol imprint. How adorable is that?

Though we tried to keep our list short and sweet, the gift options for the day are as endless as Pi.
