教学思路

本课的教学重点在于引导学生观看图片,理解语境,从本课时的需要出发,先学习十以上的数词,进一步引导学生在听力、口语活动中运用,回答多久、多远等问题。以活动和任务引起学生的听说兴趣,训练学生的听力和口语表达能力。利用图片辅助听力和说话,同时在对话中反复运用新学的单词和短语。因此,教师可以将知识目标定为掌握数词的书写和读音,询问和回答how, how long和how far的句型。情感目标定为通过话题的学习,培养学生运用适当的交通工具,做到既健康又环保。

教学准备

Step Ⅱ.Listening(2a)

1.Before listening

Revise the numbers.First,0—12,next,13—19,then,teach 20—90.And teach the new word “hundred”.

T:Now,class.Let’s count from 0 to 30.We know these numbers. What do the numbers 13—19 have in words?

Ss: They all have “-teen”.

T:Yes.And in the words 20,30,…90,there is “-ty”.So we can learn these words easily. Say these numbers.20—90.

Ss: Twenty, thirty, forty,…ninety.

T:What about 99 and 87 in the word forms?

Ss: Ninety-nine and eighty-seven.

T:Yes,we use 90 and 9.Don’t forget “-”between ninety and nine. In this way we can say and write the English words for the numbers below 100.

T:Now,learn the word “hundred”.It means 100.

Ss: Hundred.

T:For more than 100,we say “one hundred and…”.For example, how can we say 103 in English? Ss: One hundred and three.

T:Very good.Now,213?
