“A book that begs for reams of colored paper, rooms full of imaginative hands, and a whole lot of clapping and giggling.”—Washington PostMichael Hall, the New York Times bestselling author of My Heart Is Like a Zoo and Red: A Crayon’s Story, inspires creativity and resilience in this strikingly illustrated picture book starring a brightly colored square. Perfect Square is the perfect choice for teaching kids to think outside the box! Young readers will learn days of the week and colors of the rainbow, as well as emotional resilience. In brilliant, innovative collage artwork, Michael Hall illustrates how a happy square transforms itself after facing one challenge after another. Cut into pieces and poked full of holes? Time to become a burbling fountain! Torn into scraps? Grow into a garden! Day after day, the square reinvents itself, from simple and perfect to complex and perfect . . . and always happy. “A near perfect concept book . . . a book to revisit often, and with delight.”—The Horn Book “Pages are lusciously intense as we watch versatility trump geometry”—The Chicago Tribune
