When I first read the title of this book, The Highest Number in the World, I wasn't quite sure what to expect. Was this a picture book about counting? Perhaps about a googol? Maybe something to do with infinity? I looked at the cover. A bird's eye view of a girl geared up for hockey. Standing in the middle of an ice rink. Looking upward. At some sort of banner. But what exactly was so important about the banner and what did this 'highest number' mean, I wondered.
