Nighttime is Number Time: Bathtime, Mathtime by Danica McKellar

BATHTIME, MATHTIME, 1 2 3.

COUNTING HELPS ME ADD, YOU SEE!

For toddlers, anytime is a teaching time, and bathtub time is a fine time to teach some math skills. Little ones' growing brains soak up learning like, well, sponges, and sleeping on a new skill helps it stay until another day.

ONE FOOT, ANOTHER FOOT!

THAT MAKES TWO!

In her brand-new math book, author Danica McKellar's Bathtime Mathtime (Random House, 2018), works early addition skills into a counting book which makes use of bathtime paraphernalia--three yellow rubber duckies add another to make four, and four bubbles ride the waves with five splashes.

In easy-going rhymes, counting skills become simple addition each time one more is added, and it's all good fun with Alicia Padron's charming illustrations of the bathtime scene, with a cute pup even getting into the action. To this sturdy board book, the book designer adds finger tabs alone the right margin to reinforce the addition skills, as one clean tot counts up sudsy bubbles. For a perfect pair, read this one at bedtime with McKellar's numerical salute to Goodnight Moon, Goodnight, Numbers.

TV actress (Winnie in the Wonder Years) and math advocate Danica McKellar's other books for very young mathematicians are Do Not Open This Math Book: Addition + Subtraction, and Ten Magic Butterflies.
