Giganti, P. Jr. (2005). How Many Blue Birds Flew Away? A Counting Book With a Difference. Illus. Donald Crews. New York, NY: Greenwillow Books.

Brief Annotation: This book is about counting two sets of objects in a scene, and comparing which has more. The text is extremely patterned and predictable—the only words that change from one page to the next are the words describing the scene and objects. The final page does present a change to the pattern.
Genre: concept book
Grade level: Preschool-2
Readers who will like this: Students who enjoy counting. Students who are learning to subtract.
Response/rating: 3 This book was somewhat boring to read, but would be helpful when teaching subtraction. You could open each math lesson during your subtraction unit with a page from this book and use that as a warm up for your lesson. It would also be helpful when teaching about story problems.
One question you would ask before read aloud: “When we see a math question asking for the difference, what do we know we need to do?”
