Square numbers are super easy.
Do you think I’m nuts? “Square numbers? Don’t you have to know about multiplication and square roots and…Eeeek!”
Actually, all you need are crackers.
I bet your four-year-old could tell you which number is square.
Is 5 square? No!
Is 6 square? Nope!
7 isn’t a square either.
Neither is 8.
But look! 9 makes a square. It’s a square number!
If we were to keep building (which would require a lot of crackers) then we would see something like this.
The next square number is going to be 16.
Children who are learning about multiplication can also learn the corresponding equations that go with each square number.
1 x 1 = 1, 2 x 2 = 4, 3 x 3 = 9, 4 x 4 = 16 et cetera
So do you believe me now?
Square numbers are super fun!
(Don’t you wish you learned math this way?)
