Adventures with the Numeral I

Let's begin our journey into the past with the very first Roman numeral: I! It's the simplest of all the symbols and the start of a whole new way of looking at numbers. Let's learn about this ancient symbol!

Getting to Know the Roman Numeral I:
The Roman numeral 'I' is the starting point for a whole new counting system! It has the simplest shape possible: a single, straight line, just like the number 1. In the ancient Roman system, this symbol represented a single unit, one person, or one object. While we use Arabic numerals (like 1, 2, 3) for most of our math today, understanding Roman numerals is like learning a secret historical code. It shows us that the idea of 'one' is so important that people all over the world and throughout history have had special symbols for it.

The best learning happens through play. Here are a few simple, screen-free ideas to continue your Roman numeral adventure together and find this ancient symbol in your daily life.

Craft Stick 'I's

This is a very simple but effective hands-on activity. You'll need craft sticks (like popsicle sticks). The challenge is to use the single sticks to make the Roman numeral 'I'. Then, you can use them to represent numbers. 'How many sticks do we need to show the number one?' Just one! This activity provides a very concrete, physical representation of the numeral and reinforces the concept of a single unit. You can also glue them onto paper to create art.

First Chapter Hunt

This is a great literacy and numeracy connection. Go on a treasure hunt through the books in your house. The mission is to find books that use Roman numerals for their chapter numbers. Open up different books and look for 'Chapter I'. This shows your child a very common and important real-world use for Roman numerals. It turns book exploration into a fun detective game and shows that numbers are an important part of storytelling and organizing information.

I am Number One!

This is a confidence-building and social-emotional activity. The number one (I) is all about being a unique individual. Sit down together and make a list or a drawing of all the things that make your child 'Number One'. What are they really good at? What makes them a special and one-of-a-kind person? This activity connects the numeral 'I' to the word 'I' (as in, myself) and is a wonderful way to boost self-esteem and celebrate your child's unique talents and personality. It’s a conversation about what makes them, them.
