Perfect squares are numbers which can complete a square shape without having any extra pieces left over.

Square root is the exact opposite of perfect squares. They usually look like a check mark √ with a line on top. Square roots are 2 identical numbers when multiplied together forms a number.

For example, 8 x 8 = 64, so the square root of 64 is 8.
