It’s pretty awesome that there’s a day to celebrate math. Even better- it has a link to a tasty pastry like pie. Also, it’s pretty amazing that I teach 7th and 8th grade math and both grade levels work with pi. Pi Day happens to always fall during spring break for us, but that doesn’t mean we can’t celebrate the day or week before spring break.
At this point in the year each day we naturally review things from earlier in the year, so I take this Pi Day celebration as a way to review irrational numbers, volume of cylinders, cones, and spheres, and area and circumference of a circle. Of course, we also eat pie.
