Click Clack Moo: Cow's That Type by Doreen Cronin is a book about cows that get a hold of an old type writer and decide to go on strike against Farmer Brown. They make continuous requests/demands (for example electric blankets) in order to give Farmer Brown their milk. I would rate this book a four out of five stars and It is listed as an AD160L on the Lexile scale. I would have my students write letter to the Farmer Brown making a request from a different animal. I would make it clear that the students could choose any other animal they would see at a farm except a cow. This is a super cute book that i will have on my bookshelf for sure.
