教學(xué)目標(biāo)：上完本課后，學(xué)生通過(guò)練習(xí)和閱讀繪本，對(duì)black，orange，white，brown四個(gè)單詞的音義形的掌握更加牢固，并了解關(guān)于變色龍的科普知識(shí)。

教學(xué)資源與環(huán)境：PPT

教學(xué)過(guò)程：

Step1 .Warm up

1.Greeting.（設(shè)計(jì)意圖：創(chuàng)設(shè)英語(yǔ)課堂氣氛，走近學(xué)生。）

Step2 .Review

Task 1：Say what you see.（變色龍的各個(gè)身體部位不同的顏色的快速呈現(xiàn)）

T：Boys and girls，first，lets play a game，“Say what you see”.

T：OK! Now what animal can you see in the picture?

Yes，its a colorful chameleon.Its very happy，because it has it has many colours.

（ 設(shè)計(jì)意圖：復(fù)習(xí)單詞，激活知識(shí)儲(chǔ)備）

Step3.Practice

Task 2：：Colour the sad chameleon

T：Mike has a storybook about the chameleon.But its sad，because it doesnt have many colours.Can you help colour them?（pause，wait for answer）

T：OK！Lets try!

Look at the first picture.Make conclusions：the chameleon can change their colours when the environment changes.（設(shè)計(jì)意圖：科普知識(shí)背景的簡(jiǎn)單介紹，為后面的練習(xí)做鋪墊。）

T：On the first page，The chameleon is green because its in the jungle.

Look at the next four pictures，choose the right colour for each chameleon.

（ 設(shè)計(jì)意圖：繪本《變色龍》作為練習(xí)的載體，強(qiáng)化學(xué)生對(duì)單詞音義形的理解。）

T：On the second page，the chameleon is in the fallen leaves.What colour is it? Please choose the right colour.（pause，wait for answer）

Yes，you are right.Its orange.Now，lets colour it orange.

Look! Its at night.What colour is the chameleon? Please choose the right colour.（pause，wait for answer）

Bingo! Its black.Lets colour it black.

Now，the chameleon is on the rocks.Please choose the best answer.（pause，wait for answer）

Task 3：：Read the storybook.

T：Boys and girls，you are so helpful.Do you want to read the storybook? OK! Lets read it together!

T：Great! I like the way you read.

（設(shè)計(jì)意圖：通過(guò)閱讀繪本，進(jìn)一步加強(qiáng)學(xué)生對(duì)單詞音義形的掌握。）

Step3.Consolidation

Task 4：Listen and choose.

T：OK! Lets do some exercises.First，listen and choose.

2.Task 5：Match and colour.

T：Now，please open your English book to page 20 and finish the exercise match and colour.You have one minute to finish it.Ready? Go!

Times up! Lets check your answers.Are you right? I believe you can do it.

設(shè)計(jì)理念與特色：

1.自編《變色龍》練習(xí)及閱讀文本，讓學(xué)生通過(guò)觀察圖片和結(jié)合科普知識(shí)回答問(wèn)題，進(jìn)一步掌握四個(gè)重點(diǎn)詞匯的音形義；

2.在完成練習(xí)的過(guò)程中，引導(dǎo)學(xué)生自己觀察找出規(guī)律，培養(yǎng)學(xué)生自主學(xué)習(xí)的能力和習(xí)慣；

3.在任務(wù)型活動(dòng)中教學(xué)，強(qiáng)調(diào)運(yùn)用。

呈現(xiàn)方式：講授與演示結(jié)合，簡(jiǎn)單交互。

微反思：本節(jié)課是重點(diǎn)復(fù)習(xí)black，white，orange，brown四個(gè)詞匯。學(xué)生在一二年級(jí)時(shí)已掌握對(duì)這些詞的讀音。通過(guò)自編的一篇含有這些詞的練習(xí)和閱讀文本，讓學(xué)生對(duì)這些詞匯音義形的掌握更加牢固。另外，本節(jié)課引用了小學(xué)生感興趣的科普知識(shí)作為知識(shí)鋪墊，激發(fā)了學(xué)生學(xué)習(xí)的興趣。

微點(diǎn)評(píng)：本節(jié)微課結(jié)合文本再構(gòu)的理念較好地突破了對(duì)重點(diǎn)詞匯black，white，orange，brown音義形的理解。整節(jié)課的主線清晰，并能運(yùn)用課外的知識(shí)，創(chuàng)設(shè)情境，讓學(xué)生較好的掌握了重點(diǎn)詞匯的義和形。最后的練習(xí)結(jié)合phonics，以及整合第二單元的問(wèn)候用語(yǔ)，讓學(xué)生進(jìn)一步學(xué)會(huì)用phonics認(rèn)讀單詞，并學(xué)會(huì)靈活運(yùn)用問(wèn)候語(yǔ)。課件制作精美有趣，激發(fā)學(xué)生學(xué)習(xí)的興趣。
