Solving a word problem with negative numbers using a number line
22 October 2026
Word problems with negative numbers can seem tricky at first, especially when they use temperatures or other real-life situations. Using a number line helps your child see exactly how to move between negative and positive numbers step by step.
Worked example
The temperature in the morning was -3°C. By the afternoon, it had risen by 5°C. What is the temperature in the afternoon?
Start at -3 on the number line.
A rise of 5°C means move 5 steps to the right.
Count each step: -3 to -2, -1, 0, 1, 2.
You land on 2.
The correct answer is 2°C.

After working through this example, your child will recognise how a number line shows changes in value, even when starting below zero. They will be ready to practise similar questions and build confidence with negative numbers in word problems.
