PreS-Gr 1-In these two concept books, jaunty gouache illustrations of cartoon animals and bright geometric flaps invite children to answer questions. In Numbers, a toad asks, "How many eyes do I have?" while other queries come from a bee, chimpanzee, spider, pig, mouse, and ladybug. Facing each question are three colorful flaps with a possible answer written on the outside of each. Under the flaps, even incorrect answers offer information related to the subject. All choices include both the Arabic and written numerals. In Opposites, different critters describe themselves in one word (big, slow, fat, rough, black, loud, and soft) and ask youngsters to select the opposite term written on one of the facing flaps. The final spread depicts some of the animals seen in the book offering children a chance to match opposites. Both titles are fun and informative.-Gay Lynn Van Vleck, Henrico County Library, Glen Allen, VA Copyright 1999 Cahners Business Information.
