Can you remember what we mean by a square  number? A square number is made when we multiply a number by itself, eg. 3 x 3 = 9 or 10 x 10 = 100.

9 and 100 are square numbers.

The number that we multiplied to get a square number is the square root. So, the square root of 9 is 3 and the square root of 100 is 10.

Does that make sense? This activity is all about square roots.

Example

What number squared gives the answer 36? Or, we could ask, what is the square root of 36? In the grid above, square numbers are shown in yellow.

Find 36 and see what was multiplied together to get that answer.

6 x 6 = 36

6 squared is 36 and the square root of 36 is 6.
