Bathtime Mathtime

Rate this book
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!

Interesting premise - not sure we really need to call "counting on" a new/different math concept, but I get the idea. The rhyme is cute enough and the illustrations are neat.

First sentence:

Bathtime Mathtime, 1, 2, 3
Counting helps me add, you see!
Let's find out just how it's done.
Bathtime Mathtime starts with 1!
Bathtime Mathtime, 1, 2, 3
Getting in the bath is slippery!
Careful feet for me and you.
One foot, other foot--that makes 2!

Premise/plot: Bathtime Mathtime is a board book concept book that teaches or illustrates simple addition facts: 1+1=2, 2+1=3, 3+1=4, 4+1=5. It's set, of course, in a bathroom. It stars a naked baby, two puppies, some rubber duckies, some bubbles, and one rhyming care-giver.

My thoughts: My mother would be the first to tell you that sometimes I over-think books. That might just be the case with this board book written by a celebrity. Am I slightly hesitant to like it because a) it's about math b) it's written by a celebrity c) the rhymes are hit/miss and at times slightly awkward.

I liked the beginning. The initial rhymes on the first page worked for me. I am not a fan of the three/slippery line. But I am picky when it comes to rhythm and rhyme. Perhaps obnoxiously so. But here's where the over-thinking kicks in. WHY is the baby getting a bath with TWO puppies. What caregiver would say YES that sounds like an awesome way to spend the evening. It just seems like a big, big job to do for the fun of it. Also I'm thinking that the water looks way too deep for the baby--and the tiny puppies.

I think most readers would enjoy this one.

3.25 stars. In this book, a little boy uses bath time to review his counting skills. He plays and counts with items in the room, such as puppies, rubber duckies, and bubbles. This book can be a useful tool to teach young children basic counting and addition skills. This book has adorable illustrations.

At times, it was a little overwhelming, but I loved having the counting presented as an introduction to addition.

Great choice to use when introducing numbers to toddlers. Could only hope that "Time to wash my hair? Doesn't bother me!" would actually work! Looking forward to sharing this with my grandson.

Age: Toddler-Preschool
STEM: Math, addition

A toddler is popped in the bath after a painting mess where they practice "counting-on" addition with dogs, duckies, and bubbles. The lively, bright illustrations depict a delightful bath for the little one but this concept is just too early to introduce to the majority of toddlers. This would have made a great picture book for preschoolers but may be passed due to its "baby" board book format.
