姚華珍

教學(xué)內(nèi)容:Story time

知識目標(biāo):

1.能聽懂、會說、會讀、會寫

1)詞匯:thirteen, can, fifteen, sure, eighteen, do.

2)句型和日常用語:

How many …sdo you have?

I have … .

What do you have?

能力目標(biāo):

2.能聽懂、會說、會讀

1)詞匯: sticker, have a look, very, fourteen, sixteen, seventeen, nineteen

2)句型和日常用語:

They’re nice.

They’re very beautiful.

Can I have a look? Yes.

Can I have one? Sure.

教學(xué)重點,難點:

句型:How many …sdo you have?

I have … .

What do you have?

詞匯:thirteen, can, fifteen, sure, eighteen, do.

情感目標(biāo):通過本課時的學(xué)習(xí),不僅可以讓學(xué)生學(xué)習(xí)到有關(guān)數(shù)字的表達,同時也讓學(xué)生學(xué)會分享。當(dāng)我們有好東西時,記得與同伴分享,這樣可以獲得雙重樂趣,同時也增加了同學(xué)間的友誼。

教學(xué)準(zhǔn)備:

1.多媒體、教學(xué)光盤教學(xué)卡片

2.魔術(shù)盒一個(貼紙,小汽車,生日蠟燭等)

教學(xué)過程:

Part A. Warming up

1.Sing a song

Ten little candles.

One little ,twolittle ,

Three little candles.

Four little,five little candles.

Six little candles.

Seven little ,eight little

Nine little candles.

Ten little candles dancing.

1)聽唱歌曲回答問題

T: How many candles ?板書 unit3 How many?

Ss: Ten.

設(shè)計意圖:通過歌曲活躍氣氛,同時引導(dǎo)學(xué)生復(fù)習(xí)這些數(shù)詞,并引出標(biāo)題。

2)分小組唱一唱,個別唱的同學(xué)獎勵水果小卡片

Look,you have many fruit cards.Can you tell me what do you have?

板書:A:What do you have?

B: I have… .

設(shè)計意圖:回顧第二單元學(xué)過的水果單詞,并復(fù)習(xí)句型。

Part2 Presentation

T: Look , I have a magic box. Can you guess what do I have?

S: What do you have?

教師從魔術(shù)盒中拿出一輛玩具小汽車,并說I have a toy car.教授toy car

S: What else do you have?

T: I have some toy cars.

1)教授新單詞

T: Look at my toy cars, How many cars do I have?Count with me.板書How many …s do you have?

Ss: one two three …( 聽音讀出thirteen)

引導(dǎo)學(xué)生說出three—thirteen,注意ir /?:/的發(fā)音,增加新詞girl bird third,引導(dǎo)學(xué)生讀一讀。注意teen/ti:n/的發(fā)音,讓學(xué)生以開火車的形式朗讀thirteen,并注意three到thirteen的變化。

2)利用chant 的節(jié)奏,操練how many

How many, how many

How many cars do you have?

Thirteen, thirteen

I have thirteen cars.

設(shè)計意圖:利用chant的節(jié)奏感,訓(xùn)練了句型及數(shù)字,比較容易激起學(xué)生的學(xué)習(xí)興趣,課堂教學(xué)不會顯得太枯燥。

3)讓學(xué)生從魔術(shù)盒中摸一摸

S1:What do you have?

S2: I have some stickers. 教授新詞sticker,注意i /?/的發(fā)音

S1: How many stickers do you have?

T:let’s count.One two…fourteen.

試著讓學(xué)生拼一拼,our /?:/teen-ee- /i:/,引導(dǎo)學(xué)生自己拼讀出來

設(shè)計意圖:加強字母音標(biāo)的發(fā)音,培養(yǎng)自我拼讀的好習(xí)慣。讓學(xué)生摸一摸魔術(shù)盒中的東西,他們會更感興趣,課堂氣氛會更熱烈。

根據(jù)前面的chant,引導(dǎo)學(xué)生編一編chant

How many , how many

How many stickers do you have?

fourteen, fourteen

I have fourteen pandas. (讀的比較好的同學(xué)獎勵貼紙)

以同樣的方式讓兩位同學(xué)利用魔術(shù)盒練習(xí)對話:

A: What do you have?

B: I have some stickers.

A: How many stickers do you have?

B: I have fifteen stickers.教授新詞fifteen ,注意i /?/的發(fā)音,利用教學(xué)卡片注意five-fifteen的變化。

利用chant,學(xué)生說一說圖片上物品的數(shù)量。

總結(jié)歸納:

Three--thirteen four---fourteen five---fifteen 讓學(xué)生找一找規(guī)律,發(fā)現(xiàn)詞尾的后綴--teen,表示十幾。找到規(guī)律后,讓學(xué)生自己說一說:

six--sixteen seven--seventeen eight--eighteen nine--nineteen

教學(xué)意圖:利用找規(guī)律的方式引導(dǎo)學(xué)生自己找到數(shù)字間的規(guī)律變化,從而認識數(shù)字16-19,引導(dǎo)學(xué)生形成自我認知的好習(xí)慣。

Play a game

1)If you see a number,say out loudly,if you see a thunder,say oh, no.

2)Let’s calculate

3+9=12 5+9=14 6+7=13 8+8=16 11+7=18 15+4=19

設(shè)計意圖:通過計算及游戲的的方式既練習(xí)了數(shù)字的讀法,既有趣味性,同時加強了學(xué)生的反應(yīng)速度。在練習(xí)過程中拓展了加(plus)的概念,引導(dǎo)學(xué)生邊讀邊做。做的又快又好的同學(xué)獎勵貼紙。

4)教師搖一搖魔術(shù)盒,并說

T: I have so many things in my magic box. Do you want to have a look?

Yes or No.

Ss: Yes.

T:Ifyou want to know what’s in my magic box, you can ask: What do you have? Can I have a look?板書Can I have a look? 并注意can I 的連讀,請學(xué)生讀一讀,說一說,并讓他們看一看魔術(shù)盒,這樣他們更能理解這兩句話的含義。利用魔術(shù)盒,同桌操練。

A:What do you have ? Can I have a look?

B: Sure. Look I have some stickers.

T: Yes, you have some stickers,and they are …. 學(xué)生會給出一些形容詞: nice, cool,beautiful 等來形容漂亮的貼紙。教師則增加very ,可用兩個大拇指 來讓學(xué)生感受貼紙非常的漂亮。

設(shè)計意圖:利用自我體驗,讓學(xué)生對句子有自我的理解,同時讓他們知道怎么去表達事物特別美,我們可以使用程度副詞very.對于程度副詞的理解,可以使用圖片,利用 來表示,以圖片的形式更加直觀化的理解very.

T: Wow, they are very beautiful. Do do want to haveone.Yes or no?

S1: Yes. Can I have one?(學(xué)生說一說,同時分給他們貼紙)

設(shè)計意圖:根據(jù)自我體會,理解Can I have one 的意思,并學(xué)會分享。

Part3 Practice and extension

Look, there is a beautiful house .Can you guess whose house?

引出本文的主人公 Mike, Helen.伴隨著一陣敲門聲,Who is coming? 引出Yang ling 和Wang Bing.

1)出示第一副圖片,請同學(xué)說一說

利用圖片,一圈一圈的形式告知學(xué)生,讓學(xué)生根據(jù)圖片,填一填里面所缺的單詞,再聽音確認答案。

設(shè)計意圖:學(xué)生通過圖片感知所給信息,挖掘圖片中隱含意義,引導(dǎo)學(xué)生仔細觀察的好習(xí)慣。

2)聽錄音回答問題:

1. How many toy cars do you have,Mike?

I have .

2. How many stickers do you have, Helen?

I have . .

設(shè)計意圖:通過看圖填空,讓學(xué)生結(jié)合圖片尋找信息,提高學(xué)生的觀察能力。聽錄音回答問題,讓學(xué)生試著帶著問題去聽,很好的鍛煉他們補抓重要信息的能力。

3) Listen and imitate逐句教授發(fā)音,注意語音語調(diào)。

注意升降調(diào)的變化,讀出自豪感。

3)請兩到三組的學(xué)生上臺表演,注意語音語調(diào)的變化,及時給予獎勵與評價,可以請同學(xué)互評,給出一個最佳表演獎。朗讀形式可以多樣化:1. 單人朗讀得一顆星,兩人分角色朗讀得兩顆星,能演一演的同學(xué)得三顆星。

設(shè)計意圖:聽原音朗讀,讓學(xué)生更好的體會升降調(diào)及重音,表演可以鍛煉學(xué)生的膽量,同時也能加深學(xué)生對文章的理解力。

4)統(tǒng)計學(xué)生獲得的小貼紙:

5)T: How many stickers do you have? S: I have … .

T: Wow, you have so many stickers,are you happy? S: Yes.

T: Great.I have some stickers left,I’m happy too. We should share our things together. So that we can be more happy.

設(shè)計意圖:情感目標(biāo)的滲透,本節(jié)課主要是讓學(xué)生學(xué)會分享自己所擁有的物品。

6) 利用所學(xué)句型,請同學(xué)用自己擁有的物品說一說,演一演文本句型。

7) Let’s have a conclusion

Self-check

I can use “How many …do you have?”to ask question.

I can count 1 to 19

設(shè)計意圖:讓學(xué)生學(xué)會自我評價,及時作出調(diào)整,學(xué)的好的同學(xué)得到了表揚,學(xué)的不是很扎實的同學(xué)會課后鞏固。

D. Homework 1.假期來了,Yang ling ,Liu Tao 分別請Mike和Helen去家里做客,想一想他們會怎么介紹他們的玩具呢?(試著讓學(xué)生來總結(jié))A: Look at my …

B: They are nice / lovely. How many …s do you have?

A: I have… . Do you have any …s?

B: Yes, I do / No, I don’t. Can I have a look?/ Can I have one?

A: Yes./ OK./Sure. B:Thanks.

設(shè)計意圖:通過本文的學(xué)習(xí),學(xué)生需要運用文本內(nèi)容,學(xué)會提取信息,運用本課時的句型,表達內(nèi)心的想法,以及對美的事物,學(xué)會用一些形容詞去表達。

2. 聽錄音跟讀Story time對話。
