11+ Maths: Understanding Scale (CEM & GL)
26 October 2026
Understanding scale questions in 11+ maths
Scale questions test your child's ability to read measuring scales, number lines and dials. These are common in CEM and GL exams because they check real-life maths skills and careful calculation.
How to read a scale accurately
First, find two labelled points on the scale. Work out the difference between them. Next, count the number of small divisions between these points. Divide the difference by the number of steps to find the value of each division.
Worked example
Suppose a scale shows 200 at one mark and 300 at the next. There are 5 small divisions between them.
Step 1: 300 - 200 = 100
Step 2: 100 ÷ 5 = 20
Each division is worth 20 units.
If the pointer is two divisions past 200, the value is 200 + (2 × 20) = 240.
The correct answer is 240.
What to watch for
Check if the question asks for a reading, a difference, or a total. Always double-check where the pointer is and count from the correct labelled value. Encourage your child to practise with real-life measuring tools at home, such as kitchen scales or rulers.
Key insight: Scale questions reward careful counting and attention to detail. Practising with different types of scales improves accuracy and confidence for the 11+ exam.
