Pi Day

Pi Day Celebration


Pi Day takes place every year on 14th March. We celebrated one day early with our 9th Annual Digits of Pi competition and followed this with a puzzle solving activity for all students from Years 7 to 10.

After finding out that the 40 000th decimal digit of pi is a 1, we watched intently as the following students wowed us with their ability to memorise the digits of pi: Xuanyi Y. (Year 7), Isabella H., Kwanjin K., Nelli S. (Year 9), and Jules S. (Year 11). 

This year's winner was Isabella with 122 decimal digits of pi correctly recited without a mistake. Congratulations to her, especially, and to all the students who took part. They were rewarded for their efforts with a delicious apple pie, and the best result in each year group will receive an extra prize at an upcoming assembly.

Every year, Digits of Pi is followed by an activity to celebrate Mathematics. This year, students worked with their housemates to complete as many puzzles as they could in the time remaining after Digits of Pi. The results of this will also be announced in an upcoming assembly. Students who would like to have a go at solving some of the puzzles they personally did not have a chance to try that day should visit the Pi Day Firefly page to try the others out!

Those of you inspired to try out the Digits of Pi competition next year can find a copy of the first 360 digits at the bottom of the Firefly link above. BTW, the school record is 465 digits recited correctly!
