This book and toy set is for ages preschool to second grade. Young children will like cuddling the star of the story, a black ant stuffed animal, while you read them the storybook "Little Black Ant On Park Street". Little Black Ant on Park Street welcomes you into a busy ant city beneath the ground with many rooms connected by little tunnels--a lot like your ant farm. The text reads as a beautifully written story that weaves in plenty of facts about the little black ant. Young readers will learn how there are different rooms underground, how ants wiggle their antennae to smell food, how squirting little drops of liquid provide a scent trail, and how the sharp jaws of an ant can slice off bits of caterpillar twenty times heavier than they are. Micro book is 32 pages. Smithsonian's Backyard is a world of wonder for children intrigued by the wildlife outside their windows. These entertaining stories have an educational message that answers many questions about the habits and habitat of the animals in their own backyards. Hardcover book is 6 x 4 inches and the toy is approximately 6 inches.
