ㄅㄆㄇㄈ Teaching Website for Kids (And Grownups, Too!)
This is a fun site for kids to use to learn the phonetics of Chinese, Taiwan-style. It is in cartoon/game format, but also shows details like how to hold the mouth and tongue to make the sounds. You can either rely on a little Chinese knowledge to get started, or just click randomly to figure out what things do. Have fun!
