The international day celebrates the first three digits of the mathematical constant Pi, 3.14.
“I like Maths because there’s always a right answer,” said Charlie, whose mother had procured the pies through a friend who is a baker. Each pie featured the Pi symbol.
Repeat customer, IGS parent Susan McKendry, who bought the last two pies just before school began for the day, said she loved the idea.
“I think it’s fantastic. It’s great that the money is going towards Science activities at the School. It’s just wonderful.”
