Ten Little Caterpillars

Ten Little Caterpillars by Bill Martin Jr. is a joyful counting book that follows ten curious caterpillars as they explore the big, wide world around them.

With rhythmic, read-aloud-friendly text and bold, vibrant illustrations, young readers count along as caterpillars crawl, munch, wiggle, and—just maybe—transform into butterflies. The story blends early math skills with natural history, inviting children to notice patterns, life cycles, and the small wonders of the natural world.

The book also includes a glossary filled with intriguing facts about each caterpillar, adding an extra layer of learning for curious minds and nature-loving families.
