We celebrate Pi Day by calculating Pi

It being ‘Pi Day’ on the 3rd month and 14th day of the year (3.14 for you mathematicians) what could we do at The Troutbeck School but work on calculating Pi for ourselves. This was a real world maths problem as it required us to measure the circumference of a circle and its diameter, or count the boxes inside a circle representing its area and divide by r². See our primary students in action on their Pi projects below:




Calculating Pi using the area method


Larger circles should be more accurate but required more precision in counting!


Finding the radius



Counting up the whole and partial boxes to determine the area
