教学内容：

字母组合“ar”和“or”的发音

教学对象分析：

本次上课的是三年级的学生,他们从一年级开始学习英语,具有一定的英语口语能力.同时,在三年级的起始阶段,学习Phonics 拼读法,具有一定的单词拼读能力.很多的学生能做到见词能读,听音能写.

教学内容分析：

本次学习的是两个r音节的发音,分别是“ar”和“or”,这两个音节虽然同属一种类型,但它们的发音却完全不同,放在一起来教,既可让学生同时接触音节的发音,又不会产生混淆.

 教学重点及难点：

“ar”和 “or”的发音,并在学习了这两个字母组合发音的基础上,去拼读更多的含有该发音的单词

一、知识目标：

1、学习 “ar”和 “or”的发音，并在学习这两个字母组合发音的基础上拼读更多含有这两个字母组合的单词。

2、  在拼读新单词的过程中，学习新单词。

 二、学习策略：

1、以旧带新，通过旧单词的发音，总结出今天所学的字母组合的发音。

    2、通过游戏，竞赛等形式去学习。

3、能在小组活动中积极与他人合作，相互帮助，共同完成学习任务。

 三、情感态度：

提高学生拼读单词，记忆单词的兴趣，通过phonics单词拼读法，激发学生学习英语的兴趣，降低学生学习英语的困难度。
