A New York Times bestselling bedtime story with a math twist from Danica McKellar (well-known for her roles on The Wonder Years and The West Wing, and acclaimed author of multiple popular math books)-which sneaks in secret counting concepts on each page to help make your child smarter! This deceptively simple bedtime book, the first in the McKellar Math line, gives your child the building blocks for math success. As children say goodnight to the objects all around them-three wheels on a tricycle, four legs on a cat-they will connect with the real numbers in their world while creating cuddly memories, night after night. Actress, math whiz, and New York Times bestselling author Danica McKellar uses her proven math success to show children that loving numbers is as easy as 1, 2, 3. "The joys of counting combine with pretty art and homage to Goodnight Moon." -Kirkus "McKellar brings her enthusiasm for mathematics to a younger crowd in this gentle and well-executed counting book." -Publishers Weekly "A similarly simple, quiet feel as Margaret Wise Brown's iconic Goodnight Moon...there is a lot to count on." -Booklist "A winner for bedtimes or storytimes focusing on counting." -School Library Journal
