Balloons and bubbles are light, and a piano and a sofa are heavy—you could call them opposites. Forty fun-to-color pages offer kids a chance to identify opposites in twenty pairs of pictures. Included are a fast race car and a slow snail, a sweet pastry and a sour pickle, and an empty glass and a full suitcase. Finding opposites in the delightful illustrations provides a fun challenge. Solutions included.
