1. Chicka Chicka Boom Boom!
by: Bill Martin
The vibrant colors alone in this book make it a winner for sure, but there's also the clever rhyming as each individual letter climbs up and then falls down the coconut tree.
2. Dr. Seuss' ABC's
by: Dr. Seuss
Back with some rhyming fun and imaginary beasts and animals, Dr. Seuss goes through each letter in the alphabet with several items that begin with that letter (with the exception of X & Z, which are notably the most difficult letters.) This one has long been a family favorite, & we have the pocket board book version.
3. ABC Lift the Flap
by: Usborne Books
I certainly love books that are interactive, and this lift-the-flap features pages illustrated beautifully as well as creatively. For example, there are pages with uppercase and lowercase letters. There are pages that focus on a theme (like a toy shop or the county fair.) All letters of the alphabet are represented well in this book. (See link below.)
4. Alphabet Trucks
by: Samantha Vamos
My son is obsessed with vehicles, so we had to find a vehicle-type book with ABC's. I was astounded that there are actually all kinds of trucks; Vamos also does a trains one that is very cute.
5. Animal ABC
by: Marcus Pfister
Most kids like animals, so an ABC book about all different kinds of animals is well-liked and very educational as well. There is only one animal featured on each page, but there are small facts shared about the animal that is represented there. This book is also written in rhyme.
