Year 1 Numbers - Counting Forwards and Backwards

In KS1 Maths, practise counting forwards and backwards. Use number lines and objects to find one more, one less, and steps of 2, 5 and 10.

Fascinating Fact:

One more is the next number. One more than 8 is 9. One less is the number before. One less than 8 is 7.

In KS1 Maths, children count forwards and backwards, use number lines, and find one more or one less quickly. They also practise skip counting in 2s, 5s, and 10s to spot patterns.

  • Number line: A line with numbers in order to help count forwards and backwards.
  • One more / one less: The next number after, or the number before, a given number.
  • Sequence: Numbers that follow a rule, like counting in 2s, 5s, or 10s.
How do I teach one more and one less in Year 1?

Use a number line or cubes. Jump one step right for one more and one step left for one less, saying the numbers out loud.

What does counting backwards mean for KS1?

Counting backwards means saying numbers in reverse order, like 10, 9, 8, 7. It helps with subtraction and understanding “one less.”

How can children practise skip counting?

Clap or step while counting in 2s, 5s, and 10s, and use number lines and hundred squares to see the repeating patterns.
