What's the best way of teaching English as fas as you know?

I am also an English teacher in the intermediate level,that is grades four,five and six. For me the best way to teach the said language is through studying the correct grammar and then apply it right away in verbal communication. The saying is true that "Correct practice makes it perfect". I affirm to this because I was once an ignorant to this borrowed language,since I am not a native English speaker. But now I could write as well as speak in English fluently. If you have an opportunity, try to talk with people who speak it,whether American or British English. Then you can build the confidence in yourself. It's true because I am a living testimony.
