- Count your way to sweet dreams with help from The Wonder Years/Great American Family star, math whiz, and author Danica McKellar! This New York Times bestselling bedtime book with a math twist is perfect both for getting ready for bed and learning at home.

This deceptively simple bedtime book sneaks in secret counting concepts to help make your 2-5 year old smarter . . . and by the end, sleepier! The first in the McKellar Math line, Goodnight, Numbers 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!

"A winner for bedtimes or storytimes focusing on counting." --School Library Journal

"The joys of counting combine with pretty art and homage to Goodnight Moon." --Kirkus
