I am looking for a set of books that are about letter sounds. I've been to my local library site and I've had no luck! They are an older set of books... it's about a child (boy and girl) that go around finding letters that the specific book is about. It has one for every letter sound in the alphabet. They are fantastic and actually what taught me to read when I was 3. I know that the W book has a wagon, walrus, and watch in it if it helps any at all. PLEASE help if you can... I need these books for my classroom and September is vowel month. We're really in NEED of these. Thanks for anything you can give me!
