I recently used this book with some of my students who were beginning readers. It worked well. The book is just about the perfect level for beginning readers.
My students weren't terribly enthusiastic about the story. (The story is about the relationship between a baby bear and his mother, which is not something that young boys are very interested in.) But they put up with it well enough, and it was good reading practice for them.
The book has a very familiar feel to it. I don't remember clearly, but I must have been exposed to it in childhood myself.
The illustrations also have a very familiar feel to that, but that could be because it's illustrated by Maurice Sendak, most famous for Where the Wild Things Are (a book that I definitely remember).
When using this book in my class, I played used this Kahoot game as a review at the end: Quiz over the book "Little Bear"
