PreSchool-Grade 1–Using bright collage artwork, a clean design, and a variety of movable pieces, Crowther provides a clear and imaginative introduction to a basic concept. Each page features a word and readers must take some action–pulling a tab or turning a wheel–to discover its opposite. The pictures incorporate easy-to-understand examples in creative ways. For instance, a roller coaster (operated by a turning wheel) illustrates the difference between up and down. Youngsters can flick the switch (by moving a tab) of a flashlight to see dark and light and pull on an alligator's tongue to see how its jaws open and shut. Warmly colored backgrounds and simply rendered images keep kids' attention focused on the task at hand, and the volume's sturdy pages and reinforced tabs will survive lots of use. A fun addition to concept-book collections.–Joy Fleishhacker, School Library Journal

PreS-Gr. 1. Crowther makes good use of simple paper design to illustrate opposing concepts such as in and out, high and low, happy and sad, and full and empty. Even very young children will enjoy pulling a tab to make a thin sandwich become a thick one or to change a television screen from off to on. The circular roller coaster that cleverly illustrates up and down may even enchant their older brothers and sisters. Clean and spare, the brightly colored collage artwork pares down each picture to its essentials. Books with moveable parts have a notoriously short shelf life, but this appears to be sturdier than most. The relatively thick pages and the lift-the-flap, turn-the-wheel, and pull-the-tab technologies make it a reasonable investment for many libraries that are reluctant to purchase books with easily destroyed pop-ups. Best of all, the book offers children a good time as well as a chance to learn a thing or two. Carolyn PhelanCopyright © American Library Association. All rights reserved
