We recommend these books for early classification work because the topic — body coverings — is something children can see and touch.
The five titles (Scales, Skin, Shells, Feathers, Fur) combine excellent full-color photographs of animals in their natural habitat with simple early reading text.
A good springboard for discussion, each book includes a picture glossary, index, and Facts section. Paperback, 24 pages each.
Ages 3 - 7.
