Identifying animals can be a tough skill for young students to master. Some animals, like amphibians and reptiles, can look similar even though they are very different. Learning what makes each animal different is an important scientific building block. Through these achievable books, readers learn how to tell the difference between a bird, a fish, a reptile, and more. Each book features one animal family and calls out important identifiers for readers to look for. Through full-color photographs of each animal, readers get an up-close look at animals they may see in their everyday life and beyond.
