Pi+Day+2014

=Pi Day 2014 - Global Collaboration Project=

On March 14th students at the Wallenpaupack South Elementary School and the Wallenpaupack North Intermediate School are inviting classes from all around the globe to join us in finding pi.

Step 1 - Have students in your class identify and measure as many circular objects as you can. We are bringing pies into school to measure (because pies are tasty), but you can use any circular object that you can find. Measure the circumference and diameter of each object.

Step 2 - Record each of your measurements on our Pi Day Data Collection Spreadsheet. That spreadsheet will automatically calculate the ratio of circumference to diameter for each circle. Please make sure not to erase the data entered by other students. If possible, please enter all measurements by 1:45 PM Eastern Standard Time. At that time I will have the spreadsheet calculate the mean (average) and median values for the ratios of all the circles.

Step 3 - Either have a discussion about what pi is with your class, see how close our classes across the country (globe) came to finding pi, and discuss whether median or mean is a better statistical measurement to use in this situation, OR join me at 2PM Eastern Standard Time for a short (15 min. or so) Google Hangout where we will discuss those topics. If you are joining us for the Google Hangout, please make sure that your microphone is muted during the call (with the exception of times that your class wants to speak to others). If you would like to participate in the call, please sign up using the form below. You will need a Google account to participate (if you have a gmail address, you already have a Google account - use your same login.)
