The pronunciation rule of “o-e”
我们把元音字母加一个辅音字母（r除外），再加一个不发音的e构成的音节叫做开音节，也就是“辅音+元音+辅音（r除外）+不发音的e”。
通过观察可以发现，上面的三个单词：nose, note, Coke都符合开音节的条件，而这些单词中的字母“o”都发[ ]音。
推而广之，我们可以得出规律：字母o在开音节词中发[ ]音。

教学过程
Step 1: Warm-up & Lead-in
1. 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. Get students to chant together. （课件出示：PEP三下教材P40 Let’s spell板块中Listen，repeat and chant部分的chant内容）
Step 2: Presentation
1. Read the words.
T: Today, we have a new friend. 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
Ss: He is Mr Jones.
T: Yes, he is Mr Jones. “j” sounds /d /, “o-e” sounds / /, “n” sounds /n/, “s” sounds /z/. Read after me.

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 blackboard.
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 / /. 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.
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: Practice
1. 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
/ / in the open syllable, and “o” sounds / / 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. lost
4. 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/ /-g/g/, dog/d g/.
Lead students to find the letter “o” is in a closed syllable, so “o” sounds / / 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.
Properly remind students to write English words correctly.
Answers: 1. dog 2. nose 3. mom 4. note
Step 4: Consolidation & Extension
1. Spell the words.
Show more words on the PPT, such as smoke, phone, joke… Ask students to try to read the words according to the pronunciation rule of “o-e”.
Show more words on the PPT, such as dog, box, fox… Ask students to try to read the words according to the pronunciation rule of “o”.
2. Chant together.
（1）Show a chant on the PPT. Let students try to sing the chant.

教学反思
1. 本节语音课主要教学元音字母“o”在重读开音节中的发音规则。在教学音标时，充分调动学生的积极性，让学生在不断地感知和练习中自己总结发音规律。
2. 通过“看口型猜单词”“听音找单词”“听音写单词”活动，将所学知识运用于实践中，提高学生参与课堂学习的意识，调动其学习热情。
3. 通过听一听、读一读等多种形式来反复练习，让学生在听和读中找出发音规律及拼写规律，很好地培养了学生的分析能力和归纳总结能力。
4. 通过创编chant，将发音规则融入活泼的韵句中，降低了学生学习的难度。
