Learning about PI – the hands on way

Learning about math, the hands on way, is often a lot more understandable by the children. It is also a lot more fun.

In the video we made a large round flower bed without using a calculator.Ā 22/7 is almost the same as PI.

To understand the relationship between the circles diameter and circumference, we first put 7 tiles as the diameter, then 22 tiles around them in a circle.

The relationship between a circles diameter and circumference is š¯›‘, which is very close to 22/7, or around 3.14 in decimals. The fraction 22/7 is not exactlyĀ  š¯›‘, but 0.4ā€° greater, but when you are making a flower bed it will still work out, even with thisĀ imprecision.
