Solving a scale word problem using a scale diagram
23 October 2026
Children often find scale word problems tricky at first. Using a scale diagram helps make the link between the map and real life clear. Here's a simple example to show your child how to use the scale to solve these questions.
Worked example
On a map, 1 cm represents 5 metres in real life. A playground is 7 cm long on the map. How long is the playground in real life?
Step 1: Write the scale. 1 cm = 5 metres.
Step 2: The playground is 7 cm on the map. Multiply 7 by 5.
7 × 5 = 35
The correct answer is 35 metres.
Scale bar: 1 cm = 5 metres
After seeing this example, your child will spot when to use the scale in similar problems. They can now practise more scale word problems to build confidence.
