You get one chance to introduce Pi to your students. We want to give you some pointers on how to make sure it doesn't go over their head right of the bat.

**Introducing Pi**

You have to start this lesson by teaching them that Pi is a ratio of the Circumference of the Circle to the Diameter. This is best done visually.

**Not a Fraction!**

Show them that Pi can not be written as a Fraction and therefore is not Rational (which means it is Irrational)! This is easy to prove with a counter example. If it is not rational it must be irrational.

**The Formula**

Teaching them the Area formula for a Circle is the easy part. Spend most of your time discussing Pi, the Circumference, Diameter, and Radius and how they compare to each other. They will hear the phrase "Pi - r - Squared" for the rest of their math careers. You do not need to pound it into their heads for them to memorize the formula (Not to mention most states standardized test give them a formula sheet with it on there). #DoNotTeachToTheTest
