Roman numerals to 1,000: what children learn
Year 5 pupils learn to read Roman numerals to 1,000 (M) and recognise years written in Roman numerals. This builds on Year 4 (numerals to 100) by adding D (500) and M (1,000), and the subtractive pairs CD (400) and CM (900).
In this matching game, around two in five cards are years between 1066 and 2030, such as MCMXCIX (1999) or MMXXVI (2026). The rest are numbers from 1 to 1,000. Years are a good real-life test because they appear on buildings, foundation stones and at the end of film and TV credits.
This topic covers the Year 5 statutory requirement in the National Curriculum in England (Number – number and place value): pupils should be taught to “read Roman numerals to 1,000 (M) and recognise years written in Roman numerals”. Year 5 pupils are usually aged 9–10.
There is no direct equivalent in the US Common Core State Standards. Roman numerals are not part of the Common Core.
How to play
Pick a card on the left, then the card on the right that matches it. Each game has 6 pairs. Wrong matches are counted as mistakes, and you get three stars for a game with no mistakes.
Step by step
- Know all seven symbols. I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000.
- Know the six subtractive pairs. IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900. A smaller symbol before a larger one means subtract.
- Split into thousands, hundreds, tens and ones. MCMXCIX: M (1,000), CM (900), XC (90), IX (9).
- Add the parts. 1,000 + 900 + 90 + 9 = 1,999.
Worked examples
Example 1: CDXLIV
Working: CD = 400, XL = 40, IV = 4.
Answer: 444
Example 2: MDCCLXXVI
Working: M = 1,000, DCC = 700, LXX = 70, VI = 6.
Answer: 1776
Example 3: MMXXVI
Working: MM = 2,000, XX = 20, VI = 6.
Answer: 2026
Common mistakes and how to fix them
- Reading CM as 1,100. C before M means subtract: 1,000 − 100 = 900. MC would be 1,100.
- Getting lost in long numerals. Draw lines to split the numeral into thousands, hundreds, tens and ones before reading.
- Confusing D and M. M is for 'mille' (Latin for thousand). D is half of that: 500.
Activities to try at home
- Look for dates in Roman numerals on old buildings, war memorials and church foundation stones.
- Pause the end credits of a film to read the year it was made.
- Write family birth years in Roman numerals.
Ideas for the classroom
- Give pupils historical dates (1066, 1666, 1945) to convert both ways.
- Discuss why there is no zero in Roman numerals and how place value makes our system easier.
- Challenge: which year this century has the longest Roman numeral?

Frequently asked questions
How do you write 2026 in Roman numerals?
MMXXVI: MM (2,000) + XX (20) + VI (6).
Why are years written without a comma in the game?
Years are normally written as 1999, not 1,999, so the game follows that convention.
Is this in the US curriculum?
No. Roman numerals are not part of the Common Core.
