Why Celebrate National Day?
At the American Pie Council, we love learning! So what could be better
than a whole day dedicated to learning about pi and enjoying a slice of
pie? Nothing much comes to mind.
We think everyone should be included in Pi(e) Day festivities! Bake a
pie with your friends, classmates, or family to celebrate the wonders of
pie! Decorate the pie with pi designs! Take some extra time to focus on
math. Do some extra practice problems to make sure you're ready for
your next test. Help a friend or classmate with some hard problems.
Math will get you far in the pie worldLinda Hoskins, executive
director of the American Pie Council, was a math major in college!

packet of basic activities and recipes. For those students who have not
reached the wonders of in their studies yet, we included some work

math! So dig in to the numbers and a delicious slice of pie!
