twelve (the number)

Introduces young readers to the idea of a group of twelve, or one dozen, and of counting different numbers of smaller groups to make up a dozen.

Colorful photographs and simple text introduce young children to the mathematical concepts of comparing, adding to, taking away from, and parts of a whole, using the numbers one through twelve.

Illustrations and rhyming text present dozens--or half-dozens--of pigs, tulips, apples, eggs, socks, babies, and more. Includes related activities.
