This addition to the I Spy series of picture-fiddles features vibrant full-color photographs of classroom toys and projects that entertain, challenge, and teach. As in Marzollo and Wick's I Spy Christmas (1992), oversized pages are chock-full of delectable details; the theme allows inclusion of a variety of familiar classroom projects from blackboard exercises to dioramas and nature study. The spreads work for readers of various skill levels. They can solve fiddles by finding objects; identify letters, numbers, and colors; or work at more sophisticated concepts of comparisons, sets, and classifications. The photographs suggest dozens of enticing activities that will leave readers longing for a quick fix of poster paint and papier-mÆ’châ€š--as if the riddles themselves weren't enough reason to go happily nuts. A can't-miss crowd-pleaser. Yum. Yum. Yum.
