Pi Day 3.14.15

Yesterday, 3.14.15, was the most exact pi day we will have in 100 years.  Every Wednesday Karlie goes to math club with her girlfriends.   She runs with some smart girls and many of the moms felt they could use a little more challenge than what the school was providing.  Ellen stepped up and formed the Math Club where they are going through the 6th grade math book.  I tried to convince Karlie to go to trampoline class with Kaitlin and Hank but she really wanted to do Math Club.  She is our go getter!
One of their challenges before spring break was to see who could memorize the most digits of pi.  Karlie was relentless as she studied.  She found an App to challenge herself with.  She worked so hard every night for 2 weeks.  She memorized 108 digits!  However, at the contest she inverts digits 77 and 78, so she ended up in 3rd place behind girls that had memorized 87 and 86 digits.  She was so bummed.  :(
But she made up for it eating pie.  We made a chocolate silk pie for their celebration.  The girls then had to test the ratio of pi with my pie and a store bought pie.  They then had to calculate the cost of each piece of pie.  What a delicious way to learn math!
Since the Math Club did their Pi Day celebration last week, we had a chance to celebrate it for real yesterday!  No other way than with a blackberry pie.

Here are a few fun facts about Pi that we learned from TechHive and 9 News:

1.   No one knows for sure when Pi was discovered but the Great Pyramid of Giza has a perimeter of 1760 cubits and a height of 280 cubits, which is twice pi.  

2.  Archimedes ,around 250 BC, is the first known person to calculate pi.

3.  There is also a ratio of pi in the Bible.  Kings 7:23 says, "And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about."

4. Super computers have calculated more than a trillion digits of pi and are still going.

5. The Guinness World Record for memorizing digits of pi is 67,890.

6.  This website can tell you where the string of your birthday is within pi.  Mine is at position 51533. :)

7.  3.14 backwards looks like PIE.  Therefor the best part about pi is eating pie!

This Chocolate Silk Pie from Taste of Home was a crowd pleaser!
