With a farm of pigs as his abacus, Arthur Geisert uses elements of a search and count game to bring Roman numerals to life in this unintimidating math-concept book. First, the seven Roman numerals are equated with the correct number of piglets. Then the reader may practice counting other items—hot-air balloons, gopher holes, and more—as the remarkable adventure unfolds. (A ...more

I’ve always liked Roman numerals. During my thirteenth year I was known to record the date in my math book using Roman numerals. It would look something like this…


Ah, yes, I also threw in a bit of Latin. Just for good measure.

That said, I really enjoyed this book. In it, Arthur Geisert applies himself to helping children enjoy learning Roman numerals through an ‘I Spy’ technique. Geisert doesn’t spend a whole lot of time explaining the seven numerals, and this was, I thought, th
After my Younger son completed a lesson on Roman numerals, I found this book at our local library & picked it up thinking he would be better able to 'see' the quantities by matching the numerals with the same number of objects. Especially since his favourite animal (pigs!) was featured. I did not expect such an educational book to be so much fun. My Youngest son (7yo) even picked up the numerals quickly and spurted the answers out faster than his brothers on the last page. I had to hide the ...more

It's rare to such beautiful etchings in a contemporary picture book - so enjoy master etcher Arthur Geisert's work! Geisert's intrepid pigs, which I notice seem to be his trademark, can also be seen in books teaching counting and learning the alphabet.

It's mostly utilitarian, as it teaches Roman Numerals, but a picture book can make learning more fun - and what could be more fun than equating the roman numerals to one to 1000s of pigs. The book uses the elements of a search and count game. Very

We are gearing up to study the Romans this year. Great book to teach Roman numerals to kids (and adults).

The book is somewhat charming and informative at the same time, where the reader is treated to an "I Spy"-esq visual scavenger hunt with the numerical clues given in roman numberals. While, it might be fun to find the 'V pigs or VIII rocks', I kind of wonder how much help it is for kids to be expected to count up to 50, 100, 500, 1000 pigs just know what L, C, D, or M stands for, since arabic numerals are never used. I know even when I was a kid, I doubt I had that kind of an attention span to p ...more

This book is all about roman numerals. The pictures in the book are engaging and require attention to detail in order to understand the concept. While I think this is a great tool for learning at an individual level, I don't think this book would do well as a large group read-aloud in a classroom. If this book were to be used in a classroom, it would probably be more effective as a review of roman numerals instead of an introduction to them. It would also probably be most successful in older gra ...more

This book is a great way to introduce roman numerals with an I-spy strategy. The students have to count the pig and match them up with the roman numeral. This book is really cute and I'm sure the students will enjoy the book. On some pages the roman numeral is given and you have to find the animal. It's kind of like Where's Waldo.

Beautifully illustrated book that teaches how to use roman numerals. I like that the author doesn't tell the reader what the symbols mean, but instead requires you to count the objects.

Well done introduction to Roman Numerals. Only complaint, no ending explanation/clarification for pages... but just more of a challenge then!

My favorite part was searching for hidden things; some of them were tricky to find!
