Unit 2 What time is it? A Lets spell教学设计【内容来源】人教版 pep（2013 年版）四下 Unit2【主 题】What time is it? 【课 时】第 3 课时：A Lets spell一、 目标依据依据新课标，要求小学四年级学生在正确读出 26 个英文字母的基础上，通过感知字母组合的发音规则，建立字母组合与发音的联系，从而让学生对字母组合在单词中的基本读音有初步的认知。二、 教材分析这是本单元的第三课时。Lets spell 为语音学习，主要学习字母组合ir,ur的发音规则，通过让学生试读含有ir,ur的例词学习总结ir,ur的发音，能够根据ir,ur的发音规则读出生词，巩固学习ir,ur的音形对应关系，并能按发音规则拼写单词，进一步强化在四线格中正确书写单词，让学生对语音现象有初步的认识，为学生能更好的运用自然拼读法学习单词打下基础。三、 学情分析三年级及四年级上册教材中学生已经学过 26 个字母的读音、元音字母在开闭音节中的常规发音，对语音有了一定的基础，但依然是“丈二和尚，摸不着头脑”，不能很好的运用于单词的学习中。本课时主要让学生能够读出符合ir,ur发音规则的单词，我们应该利用学生的好奇心，好胜心激发学生的兴趣，把枯燥的语音教学变得有趣起来，并尽量当堂就让学生把所学知识学以致用，根据以前学过的单词总结出字母组合的发音规则然后拼读新词，令学生比较有成就感。四、教学目标 1. 通过读例词发音，观察例词结构中共有的特征，学习ir,ur在单词中分别发/:/的规律；能够跟着动画说唱歌谣、拆音和拼音活动强化记忆ir,ur的发音规则，做到见词能读。2. 能够根据ir,ur的发音规则读出单词,听录音为单词标序号的 活动，巩固学习ir,ur的音形对应关系。3. 通过看图、听录音、学习按发音规则拼写单词，做到听音会写并进一步强化在四线格中正确书写单词。五、教学重点难点 重点：能够读出符合ir 和ur发音规则的单词。难点：能根据已学的发音规则正确的读出小故事。6、 教学评价1.借助游戏，认读单词，说唱歌谣总结并强化ir,ur的发音规则。（检测目标1 的达成情况）2.通过听录音，完成听音标号任务。（检测目标2的达成情况）3.通过听录音完成看图写词活动，听音写单词的活动。（检测目标3 的达成情况）七、教学过程 Step1：Warm up1.T: Hello, boys and girls.
