How We Move Around

Book excerpt: (back cover) Before babies learn to walk on two legs they begin by crawling on all fours. Children who are unable to walk without aid use crutches or move around in a wheelchair. Some people, when they grow old, use a cane to help them walk--which is a little like walking on three legs. Many animals walk on four legs, insects walk on six legs, and spiders walk on eight legs. Some animals and insects fly--like birds, ladybugs, and butterflies. Turn the pages of this book and discover how different animals move from place to place.
