内容简介 They're busy and they're zippy They're happy, bright, and dippy. They're friends who play and laugh all day-- Why are these dinos dizzy? This sturdy board book has a plastic carrying handle and colorful dinosaur-shaped beads on a built-in abacus. As the bouncy rhyming story progresses, kids can move the dinos one at a time along the abacus. This book introduces the concept of addition, spread by spread. The final spread introduces subtraction as the dinos move back to their starting points.
