Teaching English or another language is not just giving facts about the language, either teaching grammar patterns.
It’s all that plus a big effort to establish communication among students and the teacher, in English.
Thus, do not interrupt too much when a kid is talking rather long in English, albeit he may have many errors and mistakes. We will polish his grammar, but the key point here is holding conversations in the classes. So foster communication, I would tell you. / Photo from: imgkid com
