2nd Grade Roman Numerals to 50 Worksheet: Write 16 Numbers with I, V, X, L

Seven-year-olds often spot Roman numerals before anyone teaches them: on a clock face, at the end of a movie, on a chapter heading. They look like a secret code, which is half the appeal, so this 2nd grade Roman numerals to 50 worksheet hands your child the key. Four reference tables fill the top of the page: the main Roman symbols from I to M, the ones from 1 to 9, the tens from 10 to 90 and the hundreds. Below, sixteen numbers from 5 to 49, labeled a to p, each wait for their Roman form. A small orange fox watches from the side. A second page gives the answer key.

Why Roman numerals sharpen place value

Roman numerals have no zero and no place value, so your child has to build each number from parts. That is exactly why they help. To write 37, your child splits it into 30 and 7, finds XXX and VII in the tables, then joins them: XXXVII.

So the page quietly practices tens and ones. The tables are arranged that way on purpose, one row for the tens and one for the ones.

The second idea is the subtract rule. A smaller symbol placed before a larger one is taken away: IV is 4, IX is 9, XL is 40. For example, 44 and 49 both use XL, then add IV or IX. Those two items are the summit of the page.

At the table: 14, 19, 44 and 49

Start with item a, 5, and ask, "Can you find 5 in the tables?" One letter, and the first answer is done.

Items j and h, 14 and 19, bring the first subtract cases. Many children write XIIII for 14. Instead of correcting, ask, "Look at the ones table. How is 4 written there?"

Items d and n, 44 and 49, are the real test. A child may write XXXXIV for 44. Point to the tens table and ask, "Which column says 40?" Then let them rebuild the number in two parts.

Finally, ask your child to read one answer back as a number. Going both ways checks the work.

Clock faces and a Roman I Spy

Take a short treasure hunt through the house. Look for these old symbols on a wall clock, on a watch, or in the chapter numbers of an older book. Also, write today's date in Roman numerals on a sticky note and put it on the fridge.

A quick game of I Spy works in any room: "I spy a Roman numeral that means nine." Your child hunts until they find it on the clock face.

Puzzles like these make the symbols familiar. Once you finish the page, check it with the answer key and praise the method: "You split each number into tens and ones first. That made the tables easy to use."
