Roman Numerals Worksheets
Free printable Roman numerals worksheets. Write numbers up to 100 as Roman numerals and read Roman numerals as numbers, with an answer key.
Roman numerals are written with seven letters: I is 1, V is 5, X is 10, L is 50, C is 100, D is 500 and M is 1,000. Each question on these sheets gives one number to turn into a numeral, such as 47 = XLVII, or one numeral to turn back into a number, such as XIV = 14. Numbers here go up to 100; the pages linked below stop at 20 or go to 1,000.
The part that takes practice is the subtractive rule: a smaller letter written before a larger one is taken away from it, so IV is 4, IX is 9, XL is 40 and XC is 90. Every numeral on these sheets is written the standard way, so the answer key shows IV and never IIII, and no letter is repeated more than three times in a row.

Frequently asked questions
How do the seven Roman numeral letters work?
I is 1, V is 5, X is 10, L is 50, C is 100, D is 500 and M is 1,000. Letters are usually added from left to right, so VIII is 5 + 3 = 8 and CLX is 100 + 50 + 10 = 160.
When is a letter subtracted?
When a smaller letter comes right before a larger one. Only six pairs are used: IV is 4, IX is 9, XL is 40, XC is 90, CD is 400 and CM is 900. So 49 is XLIX (40 + 9), not IL.
Why does the answer key show IV and not IIII?
A number has one standard Roman numeral, and the standard way never writes the same letter four times in a row. IIII does appear on some clock faces, but these sheets only ask for and print the standard form, so each question has one correct answer.
Is there a Roman numeral for zero?
No. The Romans had no symbol for zero, so every number on these sheets is 1 or more.
