Lifetime: The Amazing Numbers in Animal Lives by Lola M. Schaefer

Take a unique look at what animals will do in a single lifetime in this book that combines counting, math and fascinating scientific facts.  The book focuses on how many times a single animal will do a behavior during their life.  The facts are based on estimations and opens with a description of how the numbers were figured out and explaining that each individual animal will be different than the estimate.  The book opens with one spider’s egg sac, the sole one she will create in a lifetime.  It then goes to the ten antlers that a caribou will grow and shed and moves on by tens.  The book ends with one thousand tiny baby seahorses, the number a single male seahorse will carry and birth. 

This is a spectacular way to introduce averages to children and estimation.  It is a celebration of the information that mathematics can provide to us about nature.  Schaefer has selected a wide variety of animals and intriguing facts about each of them.  Readers can find more in-depth information on the animals at the back of the book.  They will also find more information on averages and math there. 

Schaefer’s art adds to the appeal of this book.  Her illustrations have a boldness to them, a graphic quality that really works.  They are flat and vibrant, clearly laying items on the page for counting.  The book is a joy to page through since each page offers a new animal, a new habitat to see.

One of the most visually stimulating and smart concepts for a nonfiction picture book, this one is sure to beat the averages and be read more than once.  Appropriate for ages 4-6.
