The emphasis is on fun as parent and child play “Wiggly Jiggly,” “Bear, Bee & Tabby Cat,” or “Splish, Splash, Splosh.” But since a person’s adult vocabulary is largely determined by the speech heard in the first three years of life, there’s a serious purpose behind each of these games. Each involves an important learning process, from naming objects and describing actions, to the essential math skills of matching and sorting groups of objects and recognizing numbers by sight and sound. Designed by a team of child development experts and based on the latest research on how children acquire vocabulary, logic, and number sense, these games offer a delightful way to get toddlers and preschoolers off to a brilliant start.
