11+ Maths: Solving Word Problems Involving Measures (CEM & GL)
21 October 2026
Solving word problems with measures
Word problems involving measures are a key part of the 11+ maths exams. Children are expected to read a problem, understand what is being asked, and select the correct calculation using units like centimetres, kilograms or litres.
Why these questions matter
Measure word problems test more than just calculation. They check if your child can spot the relevant information, convert between units if needed, and decide which operations to use. These skills are important for both CEM and GL exam boards.
Key insight: Encourage your child to underline units and key numbers in each question. This helps them focus on what is being measured and reduces mistakes with conversions or calculations.
Common types of measure problems
Expect questions about length, mass, volume, perimeter, area, and sometimes time. Some problems will need simple addition or subtraction. Others may ask for conversions, such as changing metres to centimetres or grams to kilograms.
Worked example
A jug contains 750 ml of juice. A child pours out 250 ml to drink. How much juice is left in the jug?
Start by identifying the operation: this is a subtraction problem.
Write the calculation: 750 ml - 250 ml.
Subtract: 750 - 250 = 500.
The correct answer is 500 ml of juice left in the jug.
Supporting your child at home
Practise reading word problems together and talk through the units involved. If a question uses different units, pause and ask your child to convert them before solving. Use real-life examples, like measuring ingredients or weighing fruit, to make practice more familiar.
Building confidence with measures
The more your child sees and solves these types of problems, the more comfortable they will become. Encourage them to check their answers and always include the correct unit at the end of their calculation.
