March 14th is Pi Day. Celebrate the mathematical fun of 3.14 with a slice of pie or two for a fun way to get kids excited about math. Here are ten recipes for pie that are quick and easy to make.

We celebrate all the nerdy holidays at my house. My kids both enjoy math, so a holiday that celebrates it and is an excuse to eat pie is perfect. My kids have argued over who has memorized pi to the most digits. If your kids don’t love math, this holiday is a great way to make it a little bit fun.

## What is pi?

In case you need a math class refresher, pi {represented by the Greek letter π} is an unendingly-long number that’s usually shortened to 3.14. To calculate the area of a circle, use the formula pi times the radius squared.

If you make a pie in a 9-inch pie plate:

- Take the radius {half the diameter}, which would be 4.5-inches.
- Square it to get 20.25-inches.
- Then multiply it by 3.14 to get 63.59-inches. That’s the area of the top of your pie.
- To make it even harder, cut the pie into 8 slices and ask the kids to figure out how much pie they get!
