Multiplying by itself (squaring)
In mathematics, we call multiplying a number by itself squaring the number.
We call the result of squaring a whole number a square or a perfect square.
You should be able to fire out the answers to all squares up to 12×12
It’s just got to be inbuilt.

This 4x4 is a big machine I’m going to get one when I’m 16.
5 x 5 = 25
Multiply by 10 and half the result.
6 x 6 = 36
Chicks, chicks, dirty chicks, six times six is thirty six.
7 x 7 = 49
Seven times seven commit a crime when they rob the number forty nine.
8 x 8 = 64
I ate (8) and I ate (8) until I was sick (6) on the floor (4) equals sixty four.
9 x 9 = 81
He stood in line (9×9) and ate one ton (81).
10 x 10 = 100
Just put a zero on the end.
11 x 11 = 121
The 11 players of the soccer team were told to mark the opposing 11 players one to one (121).
12 x 12 = 144
