Last week, we celebrated the Ultimate Pi Day (3.141592653...) with a Pi Party in the park. We had 20-30 people attend and had so much fun! Here's our Pi(e) spread complete with many homemade and store bought pies.

One of our nerdy attendees made this sign by the pie. Do you get it? Also, our local grocery store got in on the Pi Day fun...notice the price of the mini pie?

We lined the other tables with butcher paper and traced circles for Pi Day Posters and Investigating Pi. One of the attendees decided to reverse my investigating pi lesson to measuring the circumference with a string and seeing how many times she could measure the diameter from the circumference string (a little more than 3). The kids were more excited about the Pi-rate Treasure Hunt! Who can blame them?

**Pi-rate Treasure Hunt:**

I printed out an aerial Google Map of the park with clue #1 marked. The park where we had the event had a walking path, so I stuck the clues in obvious places along the path for the problems. Hints were more hidden, so the participants had to actively look for those if they needed the help. The kids had to answer 5 questions (preferably from the same set of questions) to get a prize from the treasure chest.

I had three levels of math problems for the kids to find and solve. I cut and pasted the problems onto colorful 3x5 cards:

Easy (green): Preschool

Medium (orange): k-2 grade

Hard (pink) = 3 grade+

Then I had some problems for adults (yellow) who might have accompanied their kids around. Those were more high school math, up to pre-algebra.

Here are the problems I came up with (note, my goal was to not make anyone cry).

Easy Pi-rate treasure hunt problems

Medium Pi-rate treasure hunt problems

Hard Pi-rate treasure hunt problems

Pi-rate treasure hunt problems for the adults

How did you fare on the Pi-rate Treasure Hunt questions?

How did you celebrate the Ultimate Pi Day??
