Too Many Dinosaurs

Robots and dinos become the painless purveyors of mathematical prowess in Bob Barner's first two Start Smart Math Books from Bantam/Rooster. In Space Race, two vividly hued robots, reminiscent of Calder mobiles, use geometric shapes in their competition to build the first rocket ship, while Too Many Dinosaurs finds six behemoths posing simple math problems as they emigrate from their crowded island; both jolly titles feature related activities and punch-out figures (paper $6.95 each, 32p, ages 4-8 ISBN 0-553-37567-9; -37566-0, Feb.).
