The volume, like its subject, is a perfect square, welcoming readers into a colorful, geometric romp. Opposite a shiny red page with white type sits “a perfect [red] square. It had four matching corners and four equal sides.” On the next page, the square wears a smile, because it is “perfectly happy.” On Monday, though, the square is no longer square; someone has cut it up and had at it with a hole puncher, so those shapes arrange themselves into a fountain (with red dots as water). On Tuesday, the square is torn into orange shapes and becomes a garden with the addition of a few well-placed lines. Wednesday’s green shreds become a park, Friday’s blue ribbons turn into a river. Each day, the brilliant colors change, and the square is torn, crumpled or cut. The artist adds lines—making fish, clouds, etc.—that enable readers to see the new creation. The simple language is as perfect as the initial square. Hall’s acrylic monotypes make each iteration slightly different in texture and color, so the whole is a visual feast. The entire week comes together in a “This is the house that Jack built” way at the end, when on Sunday the square becomes a window onto all that was made. Young readers will absorb the visual lessons effortlessly and with delight. (Picture book. 4-8)
