11+ Maths: Solving Data-Based Reasoning Questions (CEM & GL)
21 October 2026
Understanding data-based reasoning questions
Data-based reasoning questions ask children to interpret information from tables, charts or graphs. They are a key part of the 11+ maths exam in both CEM and GL styles because they test logical thinking and the ability to work with real-life data.
How to approach these questions
Encourage your child to read the question carefully and examine all the data shown. Remind them to look for headings, labels and units. It helps to jot down key numbers or underline important words in the question.
Tips for analysing tables and graphs
Start by identifying what each row and column means in a table, or what the axes show in a graph. Ask your child to describe what the data is about before they begin any calculations. For multi-step questions, break the task down and solve one part at a time.
Worked example
A table shows the number of books read by 4 children in a month: Anna 5, Ben 7, Cara 3, Dan 6.
Step 1: Add the numbers together: 5 + 7 + 3 + 6
Step 2: Calculate the total: 21
Step 3: The answer is 21 books read in total.
Building confidence through practice
Regular practice with different types of data questions helps children recognise patterns and become more confident. Use a mix of tables, bar charts and pictograms to keep practice varied and engaging.
Key insight: Practising data-based reasoning questions helps children develop logical thinking and attention to detail, which are crucial skills for success in the 11+ maths exam.
