A newborn and a twelve-year-old do not think the same way. Swiss psychologist
Jean Piaget spent decades watching children play, solve puzzles, and answer questions. He learned that thinking grows in clear steps, like climbing a ladder. Each step adds new skills. Babies explore with hands and mouths. Toddlers use words and pretend play. School-age kids handle logic about real objects. Teenagers can reason about ideas they cannot see or touch. Piaget called these steps
stages of cognitive development. They help parents and teachers know what a child is ready to learn next.
