Year 2 Numbers - Number Lines
Number lines are a useful tool when doing additions or subtractions.

Year 2 Numbers - Number Lines

Use number lines to compare and find numbers. Jump in steps, read positions, and decide which is bigger by looking to the right.

Fascinating Fact:

Compare by position. Numbers to the right are bigger. 56 is to the right of 49, so 56 > 49.

In KS1 Maths, number lines help pupils see order, count in steps, and compare values quickly. If one number sits further right, it is greater. Careful jumps show the next or previous numbers.

  • Number line: A line with numbers in order that you can use for counting and comparing.
  • Interval: The equal space between marks on a number line, such as 1, 2, or 5.
  • Greater than (>): A symbol that shows one number is bigger than another, for example 56 > 49.

Try the Numeracy Game to jump along number lines, spot intervals, and compare numbers quickly.

How do I compare numbers on a number line?

Find both numbers on the line. The number further to the right is greater. If they are at the same place, they are equal.

What are the jumps on a number line in Year 2?

Year 2 number lines often jump in 1s, 2s, 5s, or 10s. The interval tells you how much each step increases.

How do I find a missing number on a number line?

Work out the interval, then count the steps from a labelled point. Use equal jumps to reach the missing position.
