Children who love both animals and a rousing game of I Spy will have fun with this book. To give kids practice identifying similarities and differences, the book starts by pairing easy-to-distinguish animals, such as zebras and horses. Then it moves on to duos that are more difficult to tell apart, such as turtles and tortoises and seals and sea lions. Reading Animals Two by Two is like taking a walk through the zoo with an eagle-eyed friend-one who wants to know if you can spot the differences between a frog and a toad or a mole and a vole!

Animals Two by Two is part of the I Wonder Why book series, written to ignite the curiosity of children in grades K-3 while encouraging them to become avid readers. These books explore the marvels of animals, plants, and other phenomena related to biology. Included in each volume is a Parent/Teacher Handbook with coordinating activities. The I Wonder Why series is written by an award-winning science educator and published by NSTA Kids, a division of NSTA Press.
