Round is a Pancake by Joan Sullivan Baranski and Yu-Mei Han (illus.) is a rollicking concept book about round things. The colorful, boisterous illustrations make this book come alive. The text is a simple, rhyming one listing various objects that are round (cherries, buttons, pancakes, … even cartwheels). Han’s illustrations go the extra mile for a simple concept book, though, and in addition to including the items mentioned in the text, adds many more objects to which children can point that are also round (such as the decorations on dresses, picture frames in the background, balloons, etc.). My toddlers requests this book often; see if your local library has a copy!
