Becoming Reacquainted with Pi(e)

I am proud to say that I remember what these formulas mean and how I can use them.

A = π r2                     C = 2 π r

After a couple of decade hiatus from ever needing to use them, this year I have become  reacquainted well with the ubiquitous mathematical symbol, pi and its formulas.   Apparently fifth graders do a lot of finding the circumferences and areas of circle in math and being a homeschool teacher means I get a front row seat on how it all goes down.

Not that homeschooling has given me any greater insight into WHY I would use these formulas in a real life situation, but just in case any of you ever wants to find out the area of your  dinner plates or the circumference of your hula hoop,  you know who to call!

March 14th (3/14 = 3.14 = π) rolled around this year and between my newfound pi using prowess and my new kitchen, I figured I had better reason to celebrate Pi Day than I ever have before.
So we made pies.   Lots of them.

I helped my sister, AnnaLisa, make a few pies for her Pi party.  Then I made a pie for a friend.   Then I made a few more to share at our homeschool cultural night.

I made apple, lemon meringue, and chocolate.

Emma made a banana cream and  Ellie made her own caramel cheesecake--both without recipes I might add.

It was a fun and delicious way to celebrate and although I never once thought about using π while I was making pie...

but at least I know I could have if the need had arisen.
