This book is a great example of cultural diversity! On a personal level I can really relate to the girl in the book because I too am from a mixed family, my father is Mexican-American and my mother is Anglo. I think that the author did a good job of comparing the differences between the food and even the activities that the girl enjoyed with each of her grandparents. The book really showed that the girl loved each of her grandparents and enjoyed what their differences had to offer.
This book could be useful in the classroom to show students how different cultures celebrate birthdays differently. The students could possibly then share how they celebrate their birthdays at home.
