Just as in the rest of the books in the series, I am amazed at how the simple colors and shapes can combine to make such lively illustrations. The progression from single labels to simple sentences mirrors the change from simple plane shapes to the 3-dimensional shapes and the more complex scenes. It all works together very well. What concepts will Katja add to the collection next?
—The Fairview Review

A wonderful and interactive shape book for little ones and preschool learners. […] the questions posed throughout the book […] make this a great first shape book. Along with the high contrast, simple and bright illustrations, the small shape of the book itself along with sturdy binding allows this to be a great book for small hands.
