Dr. Seuss's ABC This book has been around for over 50 years!
The pictures are fun and it is a great introduction to beginning letter sounds--in real as well as imaginative words. I don't suggest reading it in its entirety to a younger child--a few pages at a time would be easier and much more enjoyable.
Do you like watermelon? Macaroni and cheese? Lollipops? Well, so do we! The Food Alphabet is a super-delicious way to familiarize kids with beginning letter sounds. Try out this simple song book, then enjoy a snack! It's also a great springboard to discussing healthy (and some not so healthy) foods. You can try your hand at some food art, too. Pick a favorite food to go with each letter, take pictures, and make your own Food Alphabet book.
Chicka Chicka Boom Boom is a popular rhythmic tale of letter names.
