# Happy Pi Day 2009!

Just in case Pi Day is new to you, we thought we’d list out the top Pi Day activities for you, so everyone can celebrate Pi Day this year:

- Bake a Pie with the symbol Pi on it, measure its diameter, calculate its circumference, and eat the Pie.
- Use a piece of string to “prove” Pi by measuring other circles’ circumference & diameter.
- Recite as many digits of Pi as you can as a team taking turns, or have a memorization contest and the winner gets to eat Pie first.
- Send your friends Pi Day eCards to remind them it’s Pi Day.
- Give everyone a “High Pi” instead of a high five.
- Get creative and write a song about Pi, or listen to music based on Pi.

Happy Pi Day 2009!
