4,5/5. This book may not acheived greatness in one aspect, but it reach a very good, above average, in so many small part of it, that it became very good. The illustrations are beautiful, full of color and very attractive for kids, it bring the concept of money and waiting for what you want, it's also made in a way which can be easily taken in class to show the narrative developpement of a story (problem, solution #1, other problem, solution #2, etc.) and the moral/message behind it is very good. So much interesting aspect. I almost gave it five, just, like I said, the lack of the greastness effect, but clearly a good children book!
