Roman numerals can be confusing at first, but this book explains all about Roman numerals in a fun way that is easy to understand! There are rules to follow so that you know whether to add or subtract to find the correct number. Once you have mastered Roman numerals, you can quiz yourself with a test at the back of the book, and then try some fun activities and even break a secret code!

This is such a fun book! I love the cute illustrations and the hilarious characters. The information is clearly explained step by step in a playful way that makes it memorable. It was so interesting learning more about ancient Roman times and how we still use Roman numerals today.

I hardly read children's books for myself, but this one spoke to me. I actually learned something that has always interested me. I grew up Catholic and my grandmother's church showed the Stations of the Cross in Roman Numerals, which I never spent much time trying to learn, but always wanted to know how to read. The only thing I did not like about this book in audiobook form was the music playing constantly. I felt pulled to the music more than the actual words more than a few times. Other than that, it was entertaining and educational.
