1、人教PEP版三年级下册英语unit5 A. Letsspell教案第三课时课时内容A. Let s spell课时分析本部分为语音学习和单词书写两部分内容。通过听一听,读一读, 唱一唱的活动,展现四个语音例词:fun, run, duck, under, 让同学通过听、读、拆音等练习体会并把握字母u在单词中的发 音。本课时主要学习其在闭音节里发的短音/ a /。而本活动中 的韵句,以包含字母u的四个语音例词run, duck, under, sun 为主要内容,同学在重复诵唱好玩的韵句的同时,可以不断感受 元音字母u的发音。之后的读一读,听一听、标序号活动,同 学需要依据听到的挨次给相应的单词
2、标上序号,检验同学的听音 辨音力量,以及认读单词的力量。听一听写一写的活动通过描 红单词,使同学初步把握单词的书写要求并辨认字形。在教学过程中,需要通过多种活动,使同学自己发觉、感悟字母 的发音规律。课时目标.能够听懂、会说、认读、书写单词:run, duck, under, sun 2.能够了解元音字母u在单词中发的短音/ A /o 3.能够依据元音字母u的发音规律拼读含有本字母的单词。课时重难点.重点:能够听懂、会说、认读、书写单词:run, duck, under, sun 能够了解元音字母U在单词中发的短音/ A /o.难点:能够依据元音字母u的发音规律拼读含有本字母的单词。教学预备1

Are you ready? Let s go.不按挨次说前一句, 同学按节拍说后一句。设计意图:将前两课时中学习到的水果单词和发音联系起来,做 这样既有节拍,又有匹配反应,又有发音练习的课,既复习了已 知词汇,也复习了
4、已知语音学问,为本课时的学习供应了特别好 的铺垫和关心。Step 2 Lead in.同同学谈论感受,引出本课的语音例词。Teacher: Is the game fun? Did you have fun? Let s have fun together! Say with me, fun, fun, fun. (板书 单词)Boys read it, please.

7、听的过程中抓住关键词 汇的力量。1 .反复拼读语音例词,引导同学总结出元音字母u在单词里的发音。Teacher: Now, I point you say. Are you ready?(指 向黑板 上的单词,同学快速反应,读出单词)Teacher: What can you find from these words? Yes, they all have a u. What s the sound of the u? Let s find. Fun, /f/ / a / /n/, run, /r/ / a / /n/, sun, /s/ / a / /n/, duck, /d/ / a /
8、 /k/. What s the sound of the u? Yes, u sounds / a /. Look at my mouth, say it together, please, /a / / A / /A /.设计意图:先让同学在玩指一指、读一读的嬉戏中熟识几个语音 例词的发音。然后通过拆音的方式,让同学能够总结、发觉元音 字母U在单词里的发音。Step 4 Practice. (1)播放语音韵句,同学跟读。Teacher: Now let s listen to the chant again. Follow it, please.(2)同学表演韵句。Teacher: Let
9、 s say the chant together. You can do some actions.(3)比比谁说得快。请同学快速说出语音韵句,进行竞赛。 Teacher: Now let s say the chant quickly. Let s find the fastest one. You can practice for three minutes.

10、。 在快速挑战的过程中,使同学能够在语流中发准音,读对单词, 说对句子。1 .嬉戏:What s missing。出示五个语音例词:run, duck, under, sun,然后快速拿走一个,请同学说出消逝的单词。Teacher: Let s play a game. Look at this word. Read them please.

Please find them and number them.设计意图:此环节一方面要求同学可以精确地听出单词,另一方面还需要他们可以正确地认读单词,才能顺当完成标 序号的任务。5 .听一听,写一写。依据听到的内容,在四线三格上描红书写
13、相应的单词。Teacher: Now, please listen and write. Write the word that you heard.Fun, f-u-n, /f/ /a / /n/, run, r-u-n, /r/ /a / /n/, duck, d-u-c-k, /d/ /a / /k/, under, u-n-d-e-r, /a / /n/ /d/ / a (r)/.设计意图:同学依据老师的拼读去描红,一方面体会单词在四线 三格中的书法方式,另一方面也在书写中进一步体会字母在单词 里的发音。Step 5 Summary.编写语音小韵句,同学学唱。Teacher: It s
14、 chant time. Listen first, then say it.U,u, u, / a/,/ a/,/ a/.U is in run.U,u, u, / a/,/ a/,/ a/.U is in duck.U, u, u, / a /, / a /, / a /.
