Kindergarten-Grade 4—These titles vary in their usefulness and complexity. Consistency is a problem. In Continents, seven places are named at the beginning under "The 'A' Continents" when only six begin with that letter, and the "Q" entry is "Quartz," which is a bit specific for a book on this topic. Similarly, the first chapter of Animals is "Animals in Danger," but "Rhinoceros" represents "R." In all of the titles, specific names of things, insects, continents, or animals are mixed with generalized categories like "Habitat loss," for "H" in Environment. The books are visually appealing, with color photos on every page, and include a variety of children, animals, and natural environments. They might expose children to new words and curious creatures, but they're strictly additional purchases.
