Some kids don’t learn Roman numerals in school, and that’s a shame. Here’s the book to rectify that: Fun with Roman Numerals by David A. Adler and illustrated by Edward Miller III, who conveniently has Roman numerals after his name.
The book shows where Roman numerals are found today and explains each symbol and the rules for using it. Addition, subtraction and a hands-on activity are included in the text of the book. Informative and interesting, this is a great book for your nonfiction collection.
