人教PEP版英语四年级上册Unit2【Let’s-spell.】教案.doc

好好学习 天天向上第三課时l 課时内容A. Let’s spelll 課时分析 本部分分为语音学习和单词书写两部分内容.通过听一听,读一读,唱一唱活动,让学生通过听、读、拆音等练习体会并掌握字母i在单词中发音,本課时主要学习其在开音节里发短音/aɪ/.本活动之间韵句为:See the nice new kite,With the big number nine. Do you like the nice new kite? Yes, it is very fine. 韵句中呈现含有i开音节词汇:nice, kite, nine, fine,like,同时在教材中呈现语音例词like, kite, five, nine, rice,学生通过这些语音例词以及韵句诵读,来感受并掌握字母i在开音节里发音.之后听一听,读一读,排顺序活动,让学生将单词读音与字形结合起来,进一步训练学生听音辨音能力.听一听,圈一圈,写一写活动学生需要判断字母i在本单词中发音是属于闭音节类还是开音节类,圈出相应代表字母,并写出单词.这个活动帮助学生进一步掌握拼读规则,并根据拼读规则拼写出单词.在教学过程中,需要通过多种活动,使学生自己发现、感悟字母发音规律.l 課时目标1. 能够感知并归纳字母i在开音节(i-e结构)中发音规则2. 能够读出符合i-e发音规则单词3. 能够根据单词读音拼写出符合i-e发音规则单词l 課时重难点1.重点:能够感知并归纳字母i在开音节(i-e结构)中发音规则能够读出符合i-e发音规则单词2. 难点:能够根据单词读音拼写出符合i-e发音规则单词l 教学准备1. 多媒体課件、录音机、磁带2. 语音例词单词卡l 教学过程µ Step 1 Warm up1. TPR活动,复习上节課中指令.Teacher:Listen to me, boys and girls. Put your Chinese book in your desk. Put your pencil box on your English book. Put your maths book under your schoolbag. Put your eraser near your pencil box. Put your English book on your desk. Put your pencil box near your English book. 设计意图:通过指令活动来复习上課时学习过知识,并使学生做好上英语課准备.µ Step 2 Lead in1. 展示教材,引出语音例词.Teacher: Look, what’s this? Yes, it’s an English book. Look at the picture, how many English books are there? Yes, five. （板书单词）Read it after me, please, five, five, five. How many? （出示数字9）Nine. (板书单词) Repeat it, please, nine. （展示印有数字9风筝图片）What’s this? Yes, it’s a kite. Do you like kites? What’s on this kite? Is it nice?（板书单词five, nice, like）Let’s read them together. 设计意图:逐步出示语音例词,使学生在语境中感受词汇含义.µ Step 3 Presentation1. 播放语音韵句.学生先认真倾听.然后再跟读.Teacher:Now, let’s listen to a chant about these words. Listen carefully. Teacher: Listen to it again. Now, let’s say the chant after it. 2. 学生自由说韵句,以自己方式来打节奏.Teacher: Now, say the chant freely. You can say it with your partner. And you can clap your hands to say it. 3. 表演韵句.Teacher:Now let’s act the chant together. 设计意图:学生先倾听韵句,初步感受韵句内容.然后跟读,获取正确语音.自由读可以使学生以自己喜欢方式操练韵句,以达到熟练说韵句目.4. 引导学生发现字母发音规则.Teacher:Look at these words on the blackboard. What can you find? Yes, there is an i in the words. What is the sound of the i? Let’s read and find. （和学生一起慢慢读每一个语音例词）What is the sound? Yes, it’s /aɪ/. Look at my mouth and say with me. 设计意图:通过拼读,让学生自己发现字母发音规则,再模仿口型,获得发音正确方式.µ Step 4 Practice1. 看口型,猜单词.教师说出语音例词中一个,但不出声,学生通过观察老师口型,猜出单词,并大声读出来.Teacher: Boys and girls, let’s play a game. I will say a word. Look at my mouth carefully. Guess what word it is. And try to say it loudly.设计意图:通过观察教师口型来猜单词,有助于学生感受字母在单词发音,以及字母i发音方法.2. 快速抢读.展示单词图卡,学生快速反应,并以拼读方式读出单词.Teacher: Now, I’ll show the cards of the words. You should say it quickly. And please say it like this. like, l-i-k-e, /l/ / aɪ / /k/.设计意图:这个活动一方面锻炼了学生对于本課时中重点语音例词理解和认读能力,还进一步锻炼了他们语音准确性和拼读单词能力.3. 读一读,听一听,排序.播放录音,学生根据听到内容为教材中六个单词排序.Teacher: Let’s read, listen and number. First, read these words. Now, listen to the tape. Number the words. Teacher: Show me your answer, please. 设计意图:此活动将单词发音与字形结合起来,使学生在准确辨音基础上,区分、掌握单词字形.4. 听一听,圈一圈,写一写,根据听到内容,判断单词是闭音节（i）还是开音节(i-e),圈出相应规则字母,然后写一写听到单词.Teacher:Now, please listen, circle and write. Write the word that you heard. Five, is it i or i-e? It’s i-e. So circle i-e, then write the word five. 设计意图:学生先根据听到单词发音判断其属于闭音节还是开音节,圈出相应代表符号,再在四线三格上写一写单词.一方面体会单词在四线三格中书法方式,另一方面也在书写中进一步体会字母在单词里发音.5. 编写语音小韵句,学生学唱.Teacher: It’s chant time. Listen first, then say it. I,I, I; I, I, I, I is in like, /aɪ/, /aɪ/, /aɪ/.I, I, I; I, I, I, I is in nice, /aɪ/, /aɪ/, /aɪ/.I, I, I; I, I, I, I is in nine, /aɪ/, /aɪ/, /aɪ/.I, I, I; I, I, I, I is in big, /ɪ/, /ɪ/, /ɪ/.I, I, I; I, I, I, I is in pig, /ɪ/, /ɪ/, /ɪ/.I, I, I; I, I, I, I is in six, /ɪ/, /ɪ/, /ɪ/.6. 表演韵句.给学生练习时间,鼓励他们加入自己动作,也可以小组合作,选择小组展示韵句节拍方式,来有创意地表演韵句.Teacher:Now,let’s work in groups. Please act the chant out. You can choose the way to show it. 设计意图:通过韵句来完整呈现本課重点语音知识.在逐句跟读中,学生不知不觉地在重复、强调字母i在单词中发音,为总结、巩固其发音规律奠定了基础.µ Step 5 Summary展示语音例词图片,学生快速抢读单词,之后再齐唱韵句.Teacher:I’ll show some words quickly. Please say it loudly. Teacher: Well done. Let’s chant together. 设计意图:通过抢读单词和齐唱韵句小活动,再现了本課语音例词和语音知识,起到了总结所学目.l 課堂作业一、按正确顺序排列以下字母,将组成单词写在四线三格上.1. v i e f 2. i k e l 3. n i e n 4. i c r e二、判断以下单词中划线部分发音是（T）否（F）一致.( ) 1. big six ( ) 2. hi ice( ) 3. five six ( ) 4. kite rice( ) 5. it is ( ) 6. like big三、判断以下句子是否与图片一致.( ) 1.
