Welcome to the MATHEMATICAL SPECIES series. This will include a few maths-based poems of a Year 6-9 standard with the help of some very clever animals. First, we meet some bears who are extremely smart with circles! Enjoy!
Once upon a time I came across some bears,
Who said the area of a circle is (pi)r²,
When I asked them how to find the perimeter,
They said, “Just multiply pi by the diameter.”
But what if I could only see the radius,
The bears said, “We will teach you, just listen to us,
Double it and then multiply it by pi,
Hopefully the perimeter is what you’ll find!”
Chord, arc, segment, sector - what about these?
The bears said, “Oh, we can do those with ease,
A part of the circumference is called an arc,
So if you’re asked about this you will get the mark!
Two parts of the circumference is joined by a chord,
Don’t celebrate, there is still so much more,
A sector is an area enclosed by two radii,
You must believe us, we bears would never lie!
A chord and an arc enclose a segment,
Now you should do well in your assessment!”
Radius, sector, perimeter, chords, arcs and pi,
Now it’s time to wave these things goodbye!
