## What is pi for middle school?

Take a look at the objectives of these activities: They will be able to define pi (the circumference of a circle divided by its diameter, or that a diameter of a circle goes around the circle a bit more than 3 times). They will be able to use formulas for circumference and area using both diameter and radius.

**What is Pi Day School?**

March 14

Every March 14, mathematicians, scientists and math lovers around the world celebrate Pi Day, a commemoration of the mathematical sign pi. The unique holiday is one that is discussed by math teachers in schools across the country and bakeries and grocery stores often sell pies at a discount that day.

### What is full pi?

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

### What is Pi Day and why do we celebrate it?

It is a day to celebrate the mathematical constant pi (π) and to eat lots of pie. Pi Day celebrates the mathematical constant π (3.14). It is celebrated in countries that follow the month/day (m/dd) date format, because the digits in the date, March 14 or 3/14, are the first three digits of π (3.14).

**What is pi formula?**

By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d).

#### How do you Celebrate Pi Day in the math classroom?

Of course, we also eat pie. To complete all 9 of these math activities takes around 2 hours. You may not have time for all of the activities on this list, but over the course of several days it’s a fun way to incorporate Pi Day fun into the math classroom. You can also give some of the activities as bell work through the week leading up to Pi Day.

#### Why do we celebrate Pi Day?

It’s pretty awesome that there is a day to celebrate math and that 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 it the day or week before spring break.

**How can I teach Pi to my kids?**

Little ones may not be ready to understand the concept of pi itself, but they can get in on the fun with this activity that introduces them to circles and ratios. All you need are some paper plates, construction paper, and a few other basic supplies. Kids mix and match the pieces to make a complete “pie,” learning more about circles along the way.
