A mother duck waddles onto a bridge followed by her five ducklings. A sudden gust blows the last little duck into the river below. Its mother quacks, “What should I do? Where should I go, with four on the bridge and one below?” Each of the remaining ducklings falls into the river in turn, with Mother Duck repeating her refrain, re-stating the numbers of little ducks on the bridge and in the water each time. Eventually only she is left on the bridge until, encouraged by her brood, she joins them in the river. Subtraction, sorting, and spatial concepts are smoothly incorporated into a funny and appealing read-aloud for preschool or kindergarten. (Ages 3–6)
