Students in Grade 8 Maths this week have been working on Measurement and Geometry and today investigated a very interesting and important property of circles. By measuring the circumference and diameter of many different sized circles, they discovered that the ratio between circumference and diameter is nearly always the same. In other words, a circle’s circumference divided by its diameter is always nearly 3.1. The students have decided that this important mathematical constant deserves a name, so they have called it elcric. Now our Grade 8’s will use this intriguing number as they continue to explore circles and ellipses in Maths.
