Yoko books (Rosemary Wells)

When Yoko brings sushi to school for lunch, her classmates make fun of what she eats--until one of them tries it for himself.

Kindergartner Yoko not only learns to write her letters and numbers in English, she shows her teacher and fellow students how to write their names using Japanese calligraphy.

Despite the doubts of some classmates and her native-born Japanese mother's inability to read English, Yoko finds the key to reading and catches up with the other students in putting new leaves on the classroom's book tree.
