Learn at home with help from The Wonder Years/Hallmark actress, math whiz, and New York Times bestselling author Danica McKellar using her acclaimed McKellar Math books! Enjoy this bedtime board book with a math twist —which sneaks in secret counting concepts to help make your 2-5 year old smarter (and hopefully sleepier)! 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. 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 | Goodnight Numbers by Danica Mckellar, Board Book | Indigo Chapters
