2. 能够读出符合o-e发音规则的单词。
▶教学难点能够根据单词的读音拼写出符合o-e发音规则的单词。
▶教学准备PPT课件、语音例词单词卡等。
▶教学过程Step 1: Warm-up & Lead-in1. Enjoy a song.Play the song—Friends. Ask students to sing after the recording. （出示课件）2. Let’s chant.Play the chant for “i-e” in Unit 2 on the PPT. Get students to chant together. （课件出示：教材P16 Let’s spell板块中Read, listen and chant 部分的chant内容）Play the chant for short sound of “o” on the PPT.

Look!Show the picture of Mr Jones on the PPT.（课件出示：教材P26 Mr Jones的图片）Lead in the words of this section.T: Who is he? Teaching purpose以歌曲来热身，可以使学生在韵律中集中注意力，并激发学生的学习兴趣,让学生在轻松欢快的氛围中准备本课内容的学习。
吟唱两首和i-e及o相关的歌谣，在律动中复习o的短音发音规律，为本节课的语音教学做铺垫。
Teaching purpose逐步出示语音例词，使学生在语境中理解词汇的含义。
Ss: He is Mr Jones.T: Yes, he is Mr Jones. “j” sounds /dʒ/, “o-e” sounds /əʊ/, “n” sounds /n/, “s” sounds /z/. Read after me.Ss: …Write down “Mr Jones” on the blackboard.T: (Point at Mr Jones’ nose.) What’s this?Ss: It is Mr Jones’ nose.T: Yes, it’s his nose, nose, nose. n/n/-o/əʊ/-s/z/.Write down the word “nose” on the blackboard.T: Touch your nose, please.Let students do the action.Show another picture on the PPT.T: And what’s in Mr Jones’ left hand?Ss:It’s a note.T: Good! We write notes on our notebooks. And this is Coke. (Point at the Coke in Mr Jones’ right hand.) Do you like Coke?Write down the words “note, Coke” on the bla ckboard.Ask students to read after the teacher and practice in groups.2. Find out the rules.T: Look at these words on the blackboard. What can you find?S1: They have the same letter “o”.S2:They have the same letter “e”.T:Yes. They all have “o-e”.The letter “e” at the end is silent. What is the sound of the “o-e”? Let’s read and find.The teacher reads each word slowly with students.T: What is the sound?Ss: …T: Yes, it’s /əʊ/. Look at my mouth and read after me.Lead students to summarize the pronunciation rule of “o-e”. Present the rule on the PPT.3. Read, listen and chant. Teaching purpose通过拼读，让学生自己发现字母的发音规则，再模仿口型，获得正确的发音方式。
Teaching purpose学生先倾听韵句，初步感受韵句内容。
然后跟读，获取正确的语音。
自由吟唱可以使学生以自己喜欢的方Ask students to look at the pictures of “Read, listen and chant” carefully. Then play the recording of this part. (出示课件)Let students listen to it carefully. Next, show the listening material. (出示课件) Ask students to read it after the recording and circle the words with “o-e”. At last, lead students to chant freely with clapping their hands.4. Act out.Get students to act out the chant together.Step 3: Practice1. Guess the words.The teacher says the four words one by one in silence. The students guess the words by observing the teacher’s mouth and say them out loudly.2. Listen and do.The teacher gives out the word cards to students and says the words at random. The students listen to the teacher and raise up the corresponding word cards.3. Read, listen and tick.Present the four groups of words on the PPT. (课件出示：教材P26 Read, listen and tick部分的练习) Get students to observe them and discuss the similarities and the differences.Let students read the four groups of words. Remind students to pay attention to the different pronunciations of “o” and “o-e”. “o-e” sounds / əʊ/ in the open syllable, and “o” sounds /ɒ/ in the closed syllable.Play the recording and ask students to choose the words they hear. (课件出示：教材P26 Read, listen and tick部分的音频)Play the recording again. Check the answers together with students.Answers: 1. note 2. home 3. dog 4. lost4. Listen, circle and write.(1) Let students look at the pictures in this section and try to predict the content of the listening.(2) Let students look at the standard writing of the word “dog” in the textbook. Then read the word.T: d/d/-o/ɒ/-g/g/, dog/dɒg/.Lead students to find the letter “o” is in a closed syllable, so “o” sounds /ɒ/ here.(3) Play the recording of this section. (出示课件) Get students to judge what they hear is the open syllable(o-e) or the closed syllable（o）.(4) Let them circle the right answers, and write down the words they hear. Teaching purpose通过观察教师口型来猜单词，有助于学生感受o-e 在单词中的发音并掌握o-e 的发音方法。
Teaching purpose这个活动检验学生能否听懂所学的语音例词，提高学生的听音、辨音能力。
Teaching purpose此活动将单词的读音与词形结合起来，使学生在准确辨音的基础上，区分并掌握单词的词形。
