6 Reasons Learning Roman Numerals Will Benefit Your Child

With the Super Bowl fast approaching, I’ve been thinking a lot about roman numerals. Yes, of course I’m also thinking about football, but as a math geek and homeschool mom, it made me wonder-“Should I bother teaching my kids roman numerals?” Is this something kids need to know? And if it’s not something that they need to know in everyday life, is there any benefit to teaching them? Well I’ve come to the conclusion that kids should learn roman numerals, and here’s why.

Why do we bother teaching kids to read and write roman numerals? Here are 6 reasons that can still be beneficial to kids, even though we no longer write in this number system.

6 Reasons Why Kids Should Learn Roman Numerals:

1. We See Them in Real Life (Even if infrequently)

So learning how to read and write Roman numerals may not be imperative to surviving life in the real world, but we do see them used from time to time, and not just to represent a Super Bowl number. Roman numerals are used in outlines, book chapter headings, and on clocks, including “Big Ben” in London.

2. It Combines Math and History

Even though I think of Roman numerals as a math topic, it’s actually an important part of ancient Roman history. Teaching Roman numerals as part of a larger study on ancient Rome is a great way to combine subjects. It can also make what might seem unnecessary more interesting if you have a child who’s a history buff. For instance, did you know that Roman numerals is the first numbering system to use subtractive tallying?

3. It Provides a New Representation of Numbers

Seeing numbers represented many different ways is a great way to help kids increase their number sense and better understand how numbers work. Thinking about numbers in different ways can also help them form connections or see patterns. Writing a number as a Roman numeral is just another way to show that various forms can look different, but be equal.

4. It Can Reinforce Addition and Subtraction

Because reading Roman numerals often requires adding or subtracting the values written together, this will give kids addition and subtraction practice, as well as a chance to work on their mental math skills. (But might be more fun than a worksheet or flash cards 😉 )

5. It Can Reinforce the Idea of Place Value

Even though the letters used to write Roman numerals represent different values than our base ten system, it is still a good opportunity to point out that where a number (or letter) falls has meaning. For example, in the number 1,648, the 6 does not just represent 6, it represents 600 because of where it falls in the number.

Likewise, even though an X represents a 10 in the Roman numeral system, where it falls has meaning. In the number XX it means 10 + 10. But in the number XC it means 10 less than 100, but in the number CX it means 10 more than 100. Place value matters in either system.

6. It’s FUN!

Or at least you can make it fun! Writing in roman numerals is almost like writing in code or hieroglyphics, so use it as an opportunity to make math fun and engaging. And if your child is struggling with the math they’re currently learning, Roman numerals may be a nice break and change of pace if they’re feeling frustrated or discouraged.

So while learning to read and write Roman numerals might not be the most important math your child will learn, I believe there is still value in it.

It can be a fun way to incorporate math into your history lessons, reinforce other math concepts, or just a way to change up your normal math routine.

  1. After completing a lesson on Roman numerals, my fifth grader decided to write all of his dates in Roman numerals. Lasted for over a month! He loved it – as if writing in some secret code since his three younger sisters couldn’t read it. I suspect he will never forget what 2015 looks like in Roman numerals. Best yet – it was all his idea!!

    Thank you for some excellent links to additional practice. Three of our prominent clocks are in Roman numerals, forcing the kids to recognize 1 – 12, but I don’t think the younger ones really comprehend why those lines are in such strange combinations. 🙂

  2. Teaching kids in Grade 4 about roman numerals is ok, but addition and subtraction of those numbers, especially big numbers, complicates it for kids, and makes them loose interest, especially that they are given to much material and ways in school
