Unit4 At the farm A Lets learnLets chant教學(xué)設(shè)計 一、教材分析：本單元圍繞“At the farm”這一題材展開，學(xué)習(xí)農(nóng)場里的蔬菜和動物，以及單、復(fù)數(shù)的使用習(xí)慣。本課時是本單元的第一課時詞匯教學(xué)課。重點學(xué)習(xí)的單詞是carrot,tomato,potato和green bean,還有它們的復(fù)數(shù)形式變化carrotcarrots,tomatotomatoes,potatopotatoes和green beangreen beans,并能簡單地描述蔬菜的特征，如：Look at the green beans. Theyre so long.學(xué)生能夠理解名詞的單復(fù)數(shù)變化，并能正確地運用。尤其要注意tomatotomatoes,potatopotatoes這兩個單詞的復(fù)數(shù)形式比較特別，本課時不打算深入探討名詞的單復(fù)數(shù)變化規(guī)律，只要求學(xué)生記住就行了。因此，在授課的過程中，運用以舊帶新的方法自然引出新課內(nèi)容，讓學(xué)生新舊結(jié)合、不斷積累，將所學(xué)的語言用于生活。二、學(xué)情分析：學(xué)生從三年級開始學(xué)習(xí)PEP英語，已經(jīng)具備了一定的口語表達能力。學(xué)生在觀察能力、思維能力、語言表達能力方面都有了較好的提高，有著強烈的好奇心與動手操作的能力。他們喜歡在自己的探索中獲取知識，喜歡在玩中學(xué)，喜歡在做中學(xué)，喜歡在想中學(xué)，喜歡在用中學(xué)。三、教學(xué)內(nèi)容Unit 4 At the farm A Lets learn及Lets chant。四、教學(xué)目標1知識目標（1）能夠聽、說、認讀單詞tomato，potato，carrot，green bean。（2）能理解句子Look at the green beans.

Where are we going?Ss: Farm. T: Yes, we are going to the farm.本課的導(dǎo)入自然有趣，創(chuàng)設(shè)一個真實農(nóng)場的情景，把四種學(xué)習(xí)的蔬菜整體呈現(xiàn)給學(xué)生，使學(xué)生初步感知認識本節(jié)課學(xué)習(xí)的內(nèi)容。通過設(shè)疑提問的形式激發(fā)學(xué)生的學(xué)習(xí)興趣，使他們的注意力高度集中，有效參與到課堂學(xué)習(xí)活動中。Step 2PresentationLets learn1. Teach “carrot（s)-yummy”1) T: Lets play a guessing game: its a kind of vegetables. Its orange. The rabbits like it very much. Whats it？Ss can answer it both in Chinese and English.

(e.g., One carrot, two carrots many carrots.)教師出示word card “carrots” 并張貼，教師帶讀，抽查2小組讀。2) I like carrots. They are yummy.（出示單詞卡抽讀個別學(xué)生，教師帶讀新單詞。)趣味拍手操練chant:I like carrots. I like carrots. Yummy, yummy, yummy.（師生示范chant，學(xué)生之間pair work。）以一個謎語導(dǎo)入本課的新授知識，富有一定的創(chuàng)意，容易激發(fā)學(xué)生的好奇心，調(diào)動學(xué)生的積極性，并在自編的chant中不知不覺地學(xué)習(xí)如何描述carrot。2. Teach “Green beans-tender-long”1) T: Show a picture of “green beans” and ask “what are these? Are they carrots?Ss: No, they arent. They are green beans. Ss show the word card and drill it.2) T: Look at the green beans. Theyre tender. I like green beans, I like green beans, tender, tender, tender.

Theyre red and juicy.教師用手掰開西紅柿并展示詞卡。Then ask the boys and girls to repeat it.趣味拍手操練:I like tomatoes, I like tomatoes, juicy, juicy, juicy.在這個教學(xué)環(huán)節(jié)教師應(yīng)用了一個不同的導(dǎo)入方法，讓學(xué)生通過品嘗從而引出tomato。應(yīng)用finger游戲讓學(xué)生掌握tomato的單復(fù)數(shù)關(guān)系，避免了講語法的枯燥，符合小學(xué)生的心理特征。4. Teach “potato(es)-tasty”1) Show a bag.T: Look at the bag. Can you touch and guess “Which one is the potato?”Ss touch it and try to find out the potato.通過這個“摸一摸”游戲，引出新單詞potato，然后出示單詞卡，讓學(xué)生認讀。接著引導(dǎo)學(xué)生數(shù)一數(shù)共有多少個potato。2) Play a short game “High and low”.鞏固操練potato的讀音。3) Show the true potatoes.T: Look at the tomatoes.

This potato is big.T shows the word card “big” and let Ss read it.在這個環(huán)節(jié)里，教師讓學(xué)生通過摸一摸、猜一猜的方式引出potato。并把potato 和tomato進行了比較教學(xué)，以一個chant 加深學(xué)生對這兩個音、形近單詞的印象，最后一個環(huán)節(jié)教師又把單詞教學(xué)落實到句型中，使單詞教學(xué)更具意義。Step 3Drill1. GamesTeacher says the words and asks two students to point out the picture. Lets see who is quicker.（看圖說單詞）Guessing game: one student holds the picture, the other student guess. Use the structure:S1: what are these?S2: are they.?S1: Yes, they are. / No, they arent.BingoWrite the four words on the paper:1) For the first time: listen and tick.
