When a generous boy shares a cookie with a hungry mouse, it is the beginning of a chain of events that keeps the boy busy all day long, and might keep him busy for days to come. If you give a mouse a cookie, after all, he's bound to ask for a glass of milk, for which he'll certainly need a straw, not to mention a napkin, and a mirror to check for a milk mustache, which will only lead to him noticing that he needs a haircut. This imaginary mouse has the kind of needs a child might have; he needs a nap with a soft pillow, and he needs his drawing hung up on the refrigerator. By the end of a day with such a mouse, a boy-hero might have an idea what it's like to be a Mommy! These books were some of my favorite in class and I still love them just as much today. I would use this book in a K-1st grade classroom most likely in a small group. I think it would be a good book to teach students how cause and effect work with examples they can relate too. Not only will students learn a new reading skill they will also see that kindness that is demonstrated throughout the story.
