Hello friends! Today, we’re going on an exciting journey back in time to ancient Rome to learn about Roman numerals. Are you ready to join us? Let’s go!
Roman numerals were used in the Roman Empire over two thousand years ago. They actually started even earlier with a group of people called the Etruscans, who lived in what is now Tuscany, Italy, about 2,900 years ago. Amazing, right? The Etruscans used symbols to count, and the Romans liked this idea and created their own system. They used sticks to represent numbers, just like counting on fingers. For example, the number one was shown with one stick.
Now that we know where Roman numerals came from, let’s learn about the letters they used. The Roman numeral system uses seven capital letters, and each letter stands for a number. Here they are:
Do you think the numbers we use today are the same as Roman numerals? Not really! Our modern numbers are different. Roman numerals are additive, which means you add the values of the letters together. Sometimes, they also use subtraction.
Let’s look at some examples. If you see two X’s together, it means 20 because X is 10. So, X plus X equals 20.
Here’s an example of subtraction: IV means 4. The I is before the V, so you subtract 1 from 5, which equals 4.
Today, we use a different system called Arabic numerals, which is based on place value. But Roman numerals are still used for some things. Let’s find out where!
We use Roman numerals in the names of kings and queens, like Queen Elizabeth II. You can also see them in the names of big events like the Olympic Games or the Super Bowl. They’re used to number parts of books and even on some clocks. Have you ever seen a clock with Roman numerals? Many old clocks have them!
That’s all for today, friends! Next time, I’ll show you how to read and write Roman numerals. Don’t miss it! See you soon!

Roman Numeral Hunt: Go on a scavenger hunt around your home or neighborhood to find Roman numerals. Look at clocks, books, or even buildings. Make a list of the Roman numerals you find and try to write down what each one means using our modern number system. Can you find all the numerals from I to X?
Create Your Own Roman Numeral Clock: Use paper plates, markers, and a pair of scissors to create your own clock with Roman numerals. Draw the clock face on the paper plate and replace the numbers with Roman numerals. Practice telling time using your new clock. Can you tell what time it is when the clock shows VIII or III?
Roman Numeral Art: Use sticks, straws, or craft sticks to create Roman numerals. Try making numbers like III, VII, or IX. Arrange the sticks to form different numerals and see if you can create a number that represents your age. Share your creations with your family and explain what each numeral means.
Sure! Here’s a sanitized version of the transcript:

Hello friends! [Music] Today we’re going back in time to ancient Rome to learn about Roman numerals. Are you coming with us? Let’s go!
Roman numerals are the numbering system used in the Roman Empire more than two thousand years ago. The origin of this system is even older; it comes from the Etruscans, a civilization that lived in what is now Tuscany, Italy, about 2,900 years ago. Incredible, right? The Etruscans created a numbering system using symbols, and later the Romans were inspired by them to create a similar system. The Romans represented numbers by drawing them like sticks, meaning they drew as many sticks as units they had to count. For example, the number one is represented by one stick. People think that using sticks to represent numbers started because the Romans counted with their fingers, just like when we were little.
Now that we know the origin of Roman numerals, let’s look at the letters that make up the Roman numeral system. [Music] The numbering system is made up of seven capital letters, and each letter has a numerical value. Let’s see the value the Romans assigned to each of the letters:
– The letter I has a value of 1.
– The letter V has a value of 5.
– The letter X has a value of 10.
– The letter L has a value of 50.
– The letter C has a value of 100.
– The letter D has a value of 500.
– Finally, the letter M has a value of 1,000.
What do you think about the numbering system we use today? Is it the same as the Roman numbering system? No, of course not! In the ancient Roman Empire, the numbering system was additive, meaning each letter has a value and does not have place value. Values are represented by the sum of the symbols in the number. However, the system changed a little to also include subtraction and multiplication.
Let’s look at some examples to understand it better. In the Roman numbering system, two letter X’s represent the number 20 since the letter X has a value of 10. So, if we add two letter X’s, it’s like adding 10 plus 10, which gives us 20. [Music]
Now, let’s see an example of how we use subtraction in Roman numerals. The letters I and V represent the number 4. Since the I is to the left of the V, we subtract its value from that of the V. The value of V is 5, and the value of I is 1, so we subtract 5 minus 1 to get the number 4. [Music]
Today, the numbering system we use is of Arabic origin. This is a place value system, which means that the value of each digit depends on its position in the number. We still use Roman numerals for some things. Let’s have a look at where!
[Music] We use Roman numerals in the names of kings and queens, like Queen Elizabeth II. [Music] We can also see Roman numerals in the names of sporting events, like the Olympic Games or the Super Bowl. People also use them to number the volumes or parts of some books. We can even see them on some clocks. Have you ever seen a clock with Roman numerals? Lots of old clocks have them.
That’s all for today, friends! Next time, I’ll show you how to read and write Roman numerals. Don’t miss it! See you soon! [Music]
