Young children can trace the raised shapes of numbers 1 to 12 to familiarize themselves with how they look and begin to practice the hand-eye coordination skills required for writing. Each number is presented in numeral and word format and is accompanied by a silly sentence and illustration such as "Three whales in party hats," "Six parachuting insects," and "Ten crabs playing cards." Talking about the pictures helps to familiarize babies with patterns of speech.
