Growing up, this was one of my favorite books to read. I remember checking it out several times at my schools library. This book is perfect for the students who love animals and especially love farm animals. Doreen Cronin writes this book perfectly to enable its use in the classroom to promote writing letters. The format the cows use is exactly how a letter should be written and it would be a great example to show younger students. You could have the students write a letter to Farmer Brown, the cows, or just a parent but the guidelines shown in the text are perfect for a lesson in writing letters. This book is leveled at a AD160L on the Lexile Leveling system.
