Circles, circles, and more circles. Chalk art circles, bubbles, round foods, circle themed lawn games, recycled bottle top art, and of course, activities related to Pi. Not the delicious pie that you eat, but Pi (π), the sixteenth letter of the Greek alphabet, and the irrational number representing the ratio of a circle’s circumference to its diameter. For any circle, the distance around the edge is a little more than three times the distance across.

In celebration of the International Day of Mathematics (IDM), Cairns Children’s Museum (CCM) applied for and received a Cairns Regional Council Community Grant to host Pi Day: A Celebration of Circles, at Tanks Arts Centre (because they are round!) on Sunday, March 14th, 2021 (3.14 in the month/day format). All aspects of the day had a circle theme and STEAM focus. The goal was for people to learn about Pi (π) in a hands-on, interactive way, and show children (and adults) that there is math all around us, and that learning about it can and should be fun! 

The day was a huge success! There were activities for those young and old. Pi Activity Packs were created for primary school students; the Tot Spot, bubbles, and chalk were a huge hit with the littlies (it’s never too early to start exploring!); and parents and children were working together to calculate the circumference of Tank 3 using hula hoops and measuring tapes. The CCM team looks forward to seeing you at Pi Day 2022!
