Sets and Numbers for the Very Young This boy has two cars with which he hears, One nose that he blows. Two lips with which he sips. Two hands on which he sometimes stands. This girl is on her way to school. Her clothes are clean and neat. She has two hats upon her head. And one shoe on her feet. Ears, lips, hands, feet, fingers, hats, shoes-all come in sets. Many things come in sets. They may be sets of ten or two, one or three or a thousand. A number tells how many. With sets and numbers you learn about adding and taking away, about matching and comparing, about putting together and taking apart, about left and right, about before and after, about counting. Open this book and begin to see all that you can learn from sets and numbers.
