The Chicka Chicka 1-2-3 collection celebrates counting, explores American currency, and aids young children in the conceptualization of very large numbers. Bill Martin Jr. and Lois Ehlert again team up with singer Crystal Taliefero and Scholastic Video to create an animated story book with a catchy score. The numbers 1 through 10 climb an apple tree, followed by the tens from 10 to 100, but 0 feels left out and searches desperately for his place in the tree. In How Much is a Million?, David M. Schwartz and Steven Kellogg help kids visualize just how much a million, billion and trillion are with the aid of Marvelosissimo the Mathematical Magician and examples like the estimated height of one million kids standing one upon the other and the probable number of days it would take to count to a billion by ones. If You Made a Million takes a look at American currency, detailing how much each coin and bill is worth and exploring concepts like working to earn money, the relative costs of various items, earning interest from the bank, writing checks, and borrowing money from the bank. Finally, the bonus Millions of Cats is a 1928 black and white production featuring still drawings from the comical Wanda Gág book that chronicles an old couple's difficulty in choosing one perfect cat from a hillside thick with one million pretty cats.
