Top critical review
Although very fun for grades 2 and 3
Reviewed in the United States on June 19, 2016
The trailer video online makes it look appropriate for little kids just learning 0 to 10, or 0 to 100, but the book involves multiplying, dividing, and even roman numerals. Although very fun for grades 2 and 3, it's too advanced for most of my Junior Kindergarten students. We shortened the story and used it as an intro to the bigger concepts of grouping and dividing, but if I had known it was so much more advanced than the trailer video I would not have purchased it.
