In this merry, multi-species story cooked up with folksy warmth and humor, everybody gets a piece of the pie -- and then some. Grandma Cat makes a delicious apple pie, and there's plenty for everyone -- and even a piece left over. Grandma Mouse finds a piece of apple pie, and there's plenty for everyone -- and even crumbs left over. Grandma Ant spies some crumbs of apple pie, and there's plenty for everyone. But what's left over after cats, mice, and ants have had their fill? Little readers will eat up this scrumptious, gently math-related story that's as sweet and satisfying as a fresh-baked dessert.
