V. Teaching methods
As we all know: the main instructional aims of learning English in primary school is to cultivate pupils' basic abilities of listening and speaking and their good sense of the English language. So in this lesson I'll mainly use “Task-based” teaching method. That is to say, I will let the Ss learn in real situations, finish a task by making a survey to help the Ss to get a better understanding of the key structure of the dialogue. I will arrange four kinds of activities: singing, guessing game, finishing a survey and having a competition. And in this lesson a recorder, CAI, school things and a printed form will be needed. Students should prepare some school things.
