Complete Collection of our original 4 alphabet books. Includes language rules of English and Vietnamese, grammar rules, and illustrations for each alphabet letter. The end of the book features 2 stories to practice the word usage in context. Our vision in this book series is to create an imaginative world to help Vietnamese American children connect with their parents' cultural heritage and language. Our bilingual approach allows our young readers to learn both Vietnamese and English simultaneously. Our curriculum builds from foundations, in which each book in the series becomes a progression in learning.
