The third period(第三课时)Part A Lets spell 教学内容与目标课时教学内容课时教学目标Lets spell·能够感知并归纳o-e在单词中的发音规则·能够读出符合o-e发音规则的单词·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重点1. 能够感知并归纳o-e在单词中的发音规则。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。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。教学过程Step 1: Warm-up & Lead-in1. Enjoy a song. Play the songFriends. Ask students to sing after the recording. （出示课件）2. Lets chant.Play the chant for “i-e” in Unit 2 on the PPT.

Look at my mouth and read after me. Lead students to summarize the pronunciation rule of “o-e”. Present the rule on the PPT. 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式操练韵句，以达到熟练说韵句的目的。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.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。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 teachers mouth and say them out loudly.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。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.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。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. 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/-g/g/, dog/dg/.Teaching purpose学生先根据听到单词的读音判断其属于闭音节还是开音节，圈出相应的代表符号，再在四线三格上写一写单词。一方面可以体会单词在四线三格中的书写方式，另一方面也可以在书写中进一步体会字母在单词中的发音。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. noteStep 4: Consolidation & Extension1. 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”. Teaching purpose通过韵句来完整呈现本课的重点语音知识。让学生在逐句的跟读中不断重复、强调o-e和o在单词中的发音，为总结并巩固其发音规律奠定基础。2. Chant together.（1）Show a chant on the PPT. Let students try to sing the chant.（2）Act out the chant.Give students some time to practice it. Encourage them to add their own actions. Let them work in groups and choose the ways they like to chant creatively.板书设计作业设计1. Read “Lets spell” three times after the recording.2. Do the exercises.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。Teaching Contents & Teaching AimsLets spell·Be able to perceive and generalize the pronunciation rule of “o-e” in the words.·Be able to read the words that conform to the pronunciation rule of “o-e”.·Be able to spell the words that conform to the pronunciation rule of “o-e” according to the words pronunciations.Teaching Priorities·Be able to perceive and generalize the pronunciation rule of “o-e” in the words.·Be able to read the words that conform to the pronunciation rule of “o-e”.Teaching Difficulties·Be able to spell the words that conform to the pronunciation rule of “o-e” according to the words pronunciations.Teaching ProceduresTeaching StagesTeacher s ActivitiesStudents ActivitiesTeaching PurposesWarm-up &Lead-in1.
