What People Are Saying

There was a sense that this is more than ‘just a book’. It had the interactive quality of a magazine, the learning capability of an encyclopedia, and the gratifying quality of a storybook.

I appreciate the interdisciplinary approach between math, science, and the environment, and, in my several years of working with younger students, I have never seen this concept communicated in such a fun way before.

I would honestly recommend this book to anyone with children in their lives (in whatever capacity)... Parents will enjoy it right alongside their kids.

Overall, this is one of the most amazing children’s book I have ever read. This is a great book not only for powerful learning information, but because it can be reread as children age and can comprehend it more each time they read it. I know adults will enjoy it as well, because the information is ageless and such a fun presentation.

Pebbles’ world was both whimsical and grounded — the vibrant, well-themed illustrations brought the whimsy while the different facts and real-world fact tidbits felt relatable.

This story serves to both ignite and satiate children’s curiosity. It makes math seem fun and approachable. Paired with polite, adorable animals, the numbers seem friendly, and the story as well as the facts make big numbers seem like something infinitely fun and interesting. Math seems like an adventure rather than something to dread.

Overall I found this book to be one of the best children’s books I’ve seen in some time, and trust me I’ve seen quite a few in the last few years.
