1. Ten Apples Up on Top
by: Dr. Seuss
We just LOVE this book at my house; I have read it at every naptime pretty consistently for a year now. The bright illustrations, and the silly animal characters (tiger, dog, & lion) who are adding apples to their heads make it a fun read. If you want an extension (for older kids) have the kids count or group the apples in each picture; especially because they can skip count by 10s at the end of the book.
2. My Very First Book of Numbers
by: Eric Carle
This book can be very basic (a colorful fruit board book for babes) or a little challenging for older kids. The idea while reading the bottom part of the book (pictures of fruit) is to match it with the black squares & corresponding number at the top of the book. (This book splits in the middle.)
3. Count the Monkeys
This clever book (written for a slightly older audience; kids 3-7) leads you to believe you will be counting monkeys. However, you are left counting creatures and humans who have scared off the monkeys until you get up to 10.
4. Curious George Learns to Count from 1 to 100
by: H.A. Rey
In this book you actually get to count with everyone's favorite curious monkey; there are different colorful objects to count on every page, with some typical Curious George mischief mixed in.
5. Five Little Monkeys/ Five Hungry Pandas
by: Alexis Barad-Cutler
These books tied for 5th because both books count down from 5. There is a song that goes along with "Five Little Monkeys" too. ;)
The panda book is in the cut-out style and it counts down (from 5 pandas) who are ready to nap but need to eat first. There are also other objects (butterflies, for instance) that your child can count with you.
