Roman numerals practice worksheets for 11+ Maths
21 October 2026
Why Roman numerals matter
Roman numerals are a common feature in 11+ Maths. Children need to read, write and convert these numbers with confidence. Practising with worksheets helps them spot patterns and avoid common mistakes.
Supporting your child at home
Start by reviewing the main symbols: I, V, X, L, C, D and M. Use worksheets that cover both conversion to and from Roman numerals. Encourage your child to work through small sets of questions, checking answers together.
Key insight: Focus on tricky rules
Pay special attention to subtractive pairs like IV for 4 or IX for 9. These are often confusing for children. Practise these with targeted worksheet questions to build confidence.
Worked example
Let's add XXV (25) and XIII (13) in Roman numerals.
First, convert each numeral to an ordinary number. XXV is 20 + 5 = 25. XIII is 10 + 3 = 13.
Add the numbers together: 25 + 13 = 38.
Now, convert 38 back to Roman numerals. 30 is XXX and 8 is VIII. So, 38 in Roman numerals is XXXVIII.
The answer is XXXVIII.
Making practice effective
Mix up question types in each worksheet. Include reading, writing, comparing and simple calculations. Regular short sessions work best, helping your child remember the key rules.
