This series features the happy melding of two popular early childhood topics: colors and animals. The opening spreads provide brief information on the color (whether it’s primary or secondary) and include a color wheel and mixing chart. . . . Eight animals are featured per book, divided into three sections: land, air, and water. . . . Readers will find definitions helpful. . . . Each spread is comprised of a large, close-up photo of the animal and two to three descriptive sentences. A selection of extensions is available on the ABDOKids.com site. These will be great additions to color units and popular for individual use as well as for group sharing.
