教案

1教學目標語言知識:

1.全班學生能聽說、讀寫并在情境中運用詞匯:beautiful,expensive,cheap,big,small,helpful,pink

2.全班學生能朗讀對話,聽說認讀:Whatcolorisit?It’spink.Isitbeautiful?It’snotbeautiful,butit’shelpful.語言技能:

1.全班學生能理解對話大意,并能正確朗讀模仿和表演對話。

2.大多數學生能在思維導圖的幫助下進行小組活動,進行拓展閱讀,以及介紹某種物品的特點。

情感態(tài)度:學生能夠通過交流、征詢別人對某種物品的看法,梳理物品相對的優(yōu)缺點,樂于表達自己的看法,培養(yǎng)擅長觀測的意識。

2學情分析

四年級學生屬于中段,是一個承上啟下的過渡階段,孩子活潑可愛,敢想、敢說、敢做,求新求異的愿望十分猛烈,并且有一定的語言基礎和語法功底。在課堂教學中,老師不僅要通過豐富多彩的課堂教學活動激發(fā)學生的興趣,而且應當重視在用中學,在學中用,“學以致用〞,最終提高學生的語言綜合運用能力。

3重點難點

詞匯expensive,cheap,helpful的音、義、形。對物品的特征描述。詞匯expensive,cheap,helpful的音、義、形。對物品的特征描述。

正確把握expensive的讀音。能借助思維導圖梳理如何描述物品特征。

4教學過程

活動1熱身1.Singasong.

Sslistenandsaysomewordsofthesong,suchasmountain,spring,beautiful.2.Talkaboutthebeautifulthingsaroundus.T:Beautifulworldaroundus.Wehavegotabeautifulclassroom.I’vegotabeautifuldress.Whathaveyougot?

Ssintroducethebeautifulthingstheyhavegot.S1:I’vegotabeautiful...

設計意圖:用歌曲導入,歡快的歌曲很簡單抓住學生的注意力。訓練學生通過聽力捕獲信息的能力。借助歌曲的語境,激活舊知,初步浮現功能句I’vegot...及形容詞beautiful,引導學生開始觀測并用學過的語言簡單描述物品的一個特點。

Sslookatthepictureandanswer:Shehasgotahat.2.Letthestudentsasksomequestionsaboutthehat.Ssaskquestions,e.g.Whatcoloristhehat?Isitred?3.Sumupthelittlestory.

設計意圖:簡單的描述圖意后,讓學生思考關于圖中hat的樣子能問出什么問題,假使學生沒有考慮到顏色,教師可以提醒Whatcolorisit?Canyouguess?幫助學生提取他們之前學過的知識:Isit...?并將此核心語言板書在黑板上,引導構建話題語言框架,而后讓學生帶著問題看視頻。既培養(yǎng)學生提問的意識,吸引他們關注故事發(fā)展,又通過問題了解他們對舊知的熟悉程度,為核心語言在文本中的學習做好鋪墊。

3.Thenletthemactoutthedialogueinpairs.Ssactinpairs.

設計意圖:通過翻卡片的游戲,學生在思維導圖上找到形容詞的同時再次關注到購買物品時考慮的因素:時間、價格、外觀(大小、顏色)、功能。從信息導圖過渡到思維導圖,培養(yǎng)學生的規(guī)律思維能力,同時為學生提供話題的內容框架,為后面自己進行語篇輸出做好鋪墊。通過學習如何根據思維導圖,進行對話和陳述,發(fā)展認知策略。
