Postscript 

We believe these 5 lessons have provided a good start to teaching Mandarin to younger children. 

We are in the process of compiling a book that will provide more drills and fun activities/exercises. From that book, the child will learn at least 54 Chinese vocabularies, which gives a solid foundation for further studies in Chinese Language and Culture. 

Most early child educators agree that giving a child an opportunity to be exposed to different phonology is a good way to form a good habit of approaching things from different perspectives and to expand his/her sense of multicultural views at an early age.
