March 14, 2011


It’s almost Pi Day (I know some wish it were Pie Day but hey, you can always celebrate Pi with Pie! :)) First, it is fun to note that this “holiday” is observed on March 14 because of the date’s representation as 3/14 in month/day date format. Moreover, this representation adheres to the commonly used approximation of 3.14 for π.

Here’s a fun video you can show to your children or class (who recognizes Winnie?? 🙂 ):

You can also celebrate Pi Day with your students and children with these great activities:
