Hap hap happy PI day!
Today is March the 14th.
So, in the UK we write our dates as day/month/year..
Show me the Maths!
Tell someone what numbers you can see in today’s date – just for fun!
In the US today’s date is
Show me the maths! What can you see?
Go and find 10, 20, 30 or MORE cylinders. They can be part of furniture, a fire extinguisher, even a post box (or pillar box as we ARE in the UK!)
Measure the diameter (width of a circle in a straight line) and circumference (the girth, all the way round the circle) of all of them and write it down.
Then take a calculator, divide the circumference by the diameter and record that number. Do you see a pattern?
Look again at today’s date – the American one. And Show me the Maths.. Tell a friend what you can see.
Another fun activity with cylinders is find several cylinders that are about the same length with differing girths. Cut a piece of string and cut it to the length of the height and circumference of them all.
Show me the maths.
What did you observe. What surprised you?
