Help your students prepare for their Maths GCSE with this free square numbers worksheet of 30+ questions and answers
A square number is the result when a number is multiplied by itself. For example, 3 \times 3=9 and so 9 is a square number. Square numbers are sometimes called perfect squares. The first 12 square numbers are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121 and 144.
The inverse of squaring a number is square rooting a number. The square root of a number is the number that is squared to get that number, so the square root of 9 is 3.
It helps to be confident with times tables when exploring square numbers and square roots.
When squaring a negative number, the answer is always positive. We must therefore be aware that the square root of a number can also have a negative solution, e.g. -4 \times -4=16 and so the square root of 16 is equal to 4 and -4.
Also, the square of an integer is always an integer (a whole number) but the square root of an integer may not always be an integer. If the square root of a number is not an integer, then this number is a surd, e.g. the square root of 3 is not an integer and so the square root of 3 is a surd.
Looking forward, students can then progress to additional powers and roots worksheets and other number worksheets, for example a multiplying and dividing decimals worksheet or an order of operations worksheet.
