Welcome to Litsy!

New York Times bestselling author Danica McKellar makes bathtime squeaky clean and sneaky smart fun in this original board book that gives your toddler a head start on learning math. Take one messy baby, two busy feet, three rambunctious friends, four wayward ducks, and five floaty bubbles--and get a tubful of fun as one family's bathtime routine turns into a nightly ritual they can "count on"! Actress, math whiz, and New York Times bestselling author Danica McKellar uses her proven math success to show children that math is all around us as she cleverly introduces the early addition concept of "counting on"--the idea that when we add 1, we can get the answer by simply counting on to the next number. This next book in the McKellar Math line shows that even washing your hair can be full of math fun!
