DK's Lift-the-Flap series introduces key subjects to children, and encourages language development, improves pre-reading skills, and teaches familiarity with activities. Each book is created to engage young minds and provide a platform for discussion between parent and child--all in a fresh and fun novelty format so exciting kids won't realize they're learning! Young children will enjoy looking at the brightly colored photographs and lifting the flaps to reveal familiar objects. In Sizes, children will learn about the different sizes of familiar objects in the world around them. Recommended for ages 2 to 5.
