Happy Pi Day (3/14)! Listed below are a few activities related to Pi!  To begin, what do you notice about the date for this year’s Pi Day?  Check the cartoon strip and read the date from either side.

Among other diversions for Pi Day, if you are looking to search Pi for any certain number sequence, such as your phone number, birthday, or any other significant sequence of numbers, this fun site searches Pi (a great opportunity to discuss irrational numbers).

  

Also, if you have extra marbles around, a flat surface, and patience, approximate Pi with an activity found here.

Finally, if you are not aware of Numberphile, you should be.  Below is one of the greatest ideas I have ever seen for calculating Pi!  Also, take very close note of the time of the video… another sign of clever!
