When you count backwards from zero, you count in negative numbers, for example -1,-2 and so on. Watch this animation from KS2 Maths to find out more.

What are positive and negative numbers?

Any number above zero is a positive number. Positive numbers are written with no sign or a + sign in front of them and they are counted up from zero to the right on a number line.

Any number below zero is a negative number. Negative numbers are always written with a - sign in front of them and they are counted down from zero to the left on a number line.

Always look at the sign in front of a number to see if it is positive or negative.

Zero, 0, is neither positive nor negative.

Activity 3

An idea to try:

  • In an open space, use post-it notes to label positive and negative numbers from 10 to -10; children could be asked to separate numbers on the number line (whichever they choose, in random order,) whilst someone else records each number that they move to.

  • Afterwards, decide on which numbers were the highest and which were lowest.

  • The number scale could be changed to represent different things, eg: a thermometer, a lift, a swimming pool or a mountain. Once the children are confident, the scale could be changed to help them understand larger positive and negative numbers.
