There are a few books from childhood that I can still recall verbatim. The B book by Stan and Jan Berenstain is one of them. There are few words on each page, which I will admit does make it easy to remember even now a few decades after it was first introduced to me.
I have used this book with early readers who are "reading" using mostly memorization and picture clues. I have read this book to my own children, and I continue to find students to share this book with.
The B Book is a timeless book for emerging readers. It's still a cute story decades after it was first introduced.
