三、教學(xué)建議第一課時:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4. Homework 1.2.
1 Each group choose one place to describe and what you are doing in it Choose one place, and describe what they are doing 2 Move around the room and give suggestions Talk about it and write it down 3 Ask one to show their works and act it Choose one of each group to make a report 4 Evaluate the best group and the best reporter Choose the best one Homework Ask your friends their ideal place and write about it教學(xué)反思:新課程標準中強調(diào)學(xué)生在課堂中的主體地位,在綜合課中他們的主體地位就更加突出。在各個活動中給不同程度的學(xué)生不同層次的任務(wù),讓各層面的學(xué)生都有表現(xiàn)發(fā)揮的機會,從而產(chǎn)生對英語的興趣。使用照片圖片多媒體來輔助教學(xué),效果更好。同時讓了解其他國家風(fēng)景,風(fēng)俗的同學(xué)介紹ideal place,增加學(xué)生的背景知知識,實現(xiàn)跨學(xué)科交流的目的。教案點評:采用任務(wù)型教學(xué)模式,在各個活動中給不同程度的學(xué)生不同層次的任務(wù),讓各層面的學(xué)生都有表現(xiàn)發(fā)揮的機會,從而產(chǎn)生對英語的興趣。使用照片圖片多媒體來輔助教學(xué),效果更好。讓了解其他國家風(fēng)景,風(fēng)俗的同學(xué)介紹ideal place,增加學(xué)生的背景知識,實現(xiàn)跨學(xué)科交流的目的。
單元整體說明(一)單元教材分析本單元的核心話題是描述動物和表達個人喜好,以及句式why do you like…? Because…。這也是本單元的教學(xué)重點。通過本單元的學(xué)習(xí),學(xué)生應(yīng)能較流利地運用所學(xué)詞匯和句型描述動物,表達個人喜好。(二)單元知識結(jié)構(gòu)1.詞匯動物名稱 tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)單元整體目標1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)單元教學(xué)重難點一覽(五)單元學(xué)情分析學(xué)生此前已經(jīng)學(xué)過由why, where, what 引導(dǎo)的特殊疑問句句型,具有了學(xué)習(xí)本單元知識的認知前提。形形色色的動物能激發(fā)學(xué)生的好奇心,產(chǎn)生了解它們的欲望,這有利于本單元知識的教學(xué)和學(xué)生學(xué)習(xí)興趣的培養(yǎng)。
學(xué)生搜集中外重要節(jié)日及部分中外名人的生日所在的月份。教師準備相關(guān)節(jié)日及部分中外名人的圖片或音像資料片。教師課前準備Let’s find out2的配圖畫好春、夏、秋、冬四個方框。錄音:Listen and number。教學(xué)過程:Warm up (熱身)活動一復(fù)習(xí)單詞教學(xué)參考時間:3分鐘(1)教師播放Let’s chant部分的歌謠,學(xué)生聽一遍后跟唱。(2)出示帶有各個月份特征的單詞卡片。學(xué)生看圖說出單詞,并一起拼讀其縮寫形式。幫助學(xué)生在有節(jié)奏的說唱中鞏固記憶單詞,為在后面活動中學(xué)生能夠熟練應(yīng)用作鋪墊?;顒佣?復(fù)習(xí)句子教學(xué)參考時間:5分鐘(1)師生同唱Let’s chant部分歌謠“When Is Your Birthday?”。(2)教師引導(dǎo)學(xué)生看歌謠下面的翻滾過山車的動畫,師生進行問答,如:When is the rabbit’s birthday? It’s in May. 等。教師示范后請學(xué)生進行Pair work,也可以展開競賽的形式進行“連鎖問答”。鞏固有關(guān)生日問答的語句,為Let’s find out1的活動做準備。
學(xué)生初步了解對話內(nèi)容,在描述中培養(yǎng)學(xué)生的語言運用能力。(2)教師讓學(xué)生自己閱讀本部分對話,不理解的生詞和句子可以和同學(xué)或老師共同商討。(3)教師幫助學(xué)生理解句子:“The weather report says it’s going to rain tomorrow. I can’t play football in the rain. I can’t go hiking, either. Let’s watch TV together.”出示圖片:1) 晴天,Zoom在踢足球,圖下顯示:today;2)天在下雨,Zoom和Zip在屋里看電視,圖下顯示:tomorrow。與學(xué)生展開對話T:What’s the weather like today? S:It’s fine/ sunny. T:What does the weather report say about tomorrow?S:It’s going to rain.T:The weather report says it’s going to rain tomorrow.(呈現(xiàn)句子)(學(xué)生重復(fù)句子The weather report says it’s going to rain tomorrow.,并說出意思。)T:Can you play football in the rain?S:No,I can’t.T:Can you go hiking ?S:No,I can’t.T:In the rain, we can’t play football. We can’t go hiking, either. (呈現(xiàn):either)學(xué)生跟讀either,感悟單詞的用法,教師講解意思:(不......),也不...啟發(fā)學(xué)生用either說兩句話:In the rain, I can’t ... I can’t ..., either,從而在應(yīng)用中鞏固單詞的讀音和用法。

教學(xué)參考時間:5分鐘(1)教師課前在教室里藏好一些動物和人物的圖片。(2)給全班學(xué)生一分鐘時間尋找。(3)請找到圖片的學(xué)生根據(jù)圖片上的人物或動物正在做的動作表演對話。活動七:猜一猜教學(xué)參考時間:5分鐘(1)教師一只手拿一張圖片,另一只手用白紙遮住圖片,一邊慢慢抽動白紙,一邊問:What are the…s doing? 學(xué)生用They are…猜圖片中的內(nèi)容。(2)猜對的學(xué)生上臺主持游戲。(3)教師也可以在白紙上剪幾個圓洞蓋在圖片上,慢慢移動白紙的位置讓學(xué)生猜白紙下面圖片的內(nèi)容。(4)也可以分組利用詞卡做該游戲。4、Consolidation and extension (鞏固與擴展)活動八:練一練教學(xué)參考時間:5分鐘(1)活動手冊Ask and write. 讓學(xué)生看一看兩個表格,找規(guī)律做問答,然后再把表格中所缺單詞寫出來。(2)活動手冊Let’s find out.讓學(xué)生仔細觀察兩幅圖找出不同的地方,并用英語表達出來?;顒泳牛盒〗Y(jié)教學(xué)參考時間:1分鐘本課我們學(xué)習(xí)了如何詢問他、她、它們正在做什么What are they doing? 及回答:They are…5、板書
(6)交流。6的乘法口訣一共有幾句?口訣中的第一個數(shù)與算式中的第二個因數(shù)相同,表示什么?口訣中的第二個數(shù)與算式的第一個因數(shù)相同,表示什么?相鄰兩句口訣的積相差幾?哪幾句難記一些?你用什么方法記呢?怎樣記住"三六十八"、"四六二十四"兩句口訣?教師在學(xué)生發(fā)言的基礎(chǔ)上鼓勵學(xué)生大膽說、想出不同記口訣的方法。(7)應(yīng)用"做一做"第1題(學(xué)生半獨立完成):①用6根小棒擺1個六邊形;②擺2個六邊形要用多少根小棒?你是怎樣想的?(想口訣"二六十二"。)③運用所學(xué)的口訣口答擺4個、6個、3個、5個六邊形所需要向小棒數(shù)。"做一做"第2題(獨立完成):①將第2題改為填空題,在圓圈內(nèi)填寫正確的積;②口答得數(shù),并說一說所用口訣。
三、利用乘法口訣進行計算1.復(fù)習(xí)口訣的含義。任意挑出一句乘法口訣(兩個因數(shù)不同的),讓學(xué)生說說它表示什么意思。如"七八五十六",使學(xué)生知道它既表示8個7相加是56,又表示?個8相加是56。2.以游戲的方式開展用口訣進行計算的活動。(1)已知兩個因數(shù)求積的游戲。方法是:請一位學(xué)生隨意說出一個兩位數(shù),另一位學(xué)生則將這個兩位數(shù)的十位數(shù)字與個位數(shù)字相乘,并算出結(jié)果,如果結(jié)果又是一個兩位數(shù),再將這個兩位數(shù)的十位數(shù)字和個位數(shù)字相乘,直至結(jié)果是一位數(shù)或零。如,一位學(xué)生說:"79",另一位學(xué)生則口算:7X9=636X3=181X8=8;一位學(xué)生說:"58":另一位學(xué)生口算:5X8=404X0=0(告訴學(xué)生0和一個數(shù)相乘得零)一位學(xué)生報了3個數(shù)以后,互換角色進行。(2)已知積求兩個因數(shù)的游戲。
過程與方法:通過閱讀保護聽力的資料,了解我們的聽力經(jīng)常受到哪些傷害,知道保護聽力的做法。情感、態(tài)度、價值觀:認識到保護聽力的重要性,養(yǎng)成良好的用耳習(xí)慣和在公共場所保持肅靜的習(xí)慣。教學(xué)重點認識到保護聽力的重要性教學(xué)難點知道各種控制噪音的方法教學(xué)準備發(fā)音罐、報紙、毛巾、棉花等
1.自學(xué)文本出示書中情境圖:有21架飛機要參加飛行表演,怎樣飛呢?想請同學(xué)們幫忙設(shè)計編組方案,下面小組同學(xué)合作,用學(xué)具擺一擺,設(shè)計出自己的編組方案,看哪個小組設(shè)計的方案最多?學(xué)生小組合作,邊擺學(xué)具邊說方案。2.交流研討哪組想到前面來匯報一下你們制定的飛行方案?(不必強調(diào)平均分,如有小組同學(xué)說出每組有7(3)架,可以分成3(7)組,或每7(3)架一組,可以分成3(7)組,老師在給予肯定的同時可以問其它小組擺法一樣嗎?之后板書算式:21÷7=3,21÷3=7。如果學(xué)生沒說出平均分,老師可引導(dǎo)說:有時表演的每組也可同樣多)
1、地位、作用和特點本節(jié)教材是北師大版小學(xué)數(shù)學(xué)二年級上冊第三單元“數(shù)一數(shù)與乘法”的第2節(jié)課(第18、19頁)。繼上一節(jié)課“有多少塊糖”對連加算式有了一定體驗的基礎(chǔ)上,結(jié)合“兒童樂園”的現(xiàn)實情境,提出并解決其中需要列連加算式進行計算的數(shù)學(xué)問題,并經(jīng)歷把相同加數(shù)的連加算式進一步抽象為乘法算式的過程,初步體會乘法運算的意義;會把相同加數(shù)的連加算式改寫為乘法算式,體會到乘法的簡便性。為后面有“有多少點子”的學(xué)習(xí)做準備。2、教學(xué)目標1)結(jié)合“兒童樂園”這一現(xiàn)實的生活情境,培養(yǎng)學(xué)生發(fā)現(xiàn)問題、提出問題和解決問題的意識和能力。2)從相同加數(shù)連加的運算中抽象出乘法算式,初步體會乘法的意義,并掌握它的讀法、寫法及各部分的名稱。3)結(jié)合具體情境,會把相同加數(shù)連加的算式改寫成乘法算式,并應(yīng)用加法計算簡單的乘法算式的結(jié)果。
一、說教材:本課時主要的內(nèi)容就是讓學(xué)生在情境中掌握兩位數(shù)加兩位數(shù)的進位加法計算,讓學(xué)生通過嘗試和探索出多種算法,體驗多種算法,然后比較出最好的算法。教學(xué)目標:1、通過具體的情境使學(xué)生更一步的理解加法的意義和提高學(xué)生的估算意識。2、通過學(xué)生的合作學(xué)習(xí)從而能探討出多種計算兩位數(shù)減兩位退位減法的方法。3、培養(yǎng)學(xué)生的數(shù)學(xué)口語表達能力,提高學(xué)生的學(xué)習(xí)興趣。4、掌握兩位數(shù)加兩位數(shù)(進位加)豎式的寫法。重點:(1)通過學(xué)生的合作學(xué)習(xí)從而能探討出多種計算兩位數(shù)減兩位退位減法的方法。(2)掌握筆算加法的計算法則。難點:對多樣化算法進行優(yōu)化,達到正確完成計算。發(fā)展學(xué)生的估算意識、和探究意識和解決實際問題的能力。二、說教法:組織學(xué)生在前面計算的基礎(chǔ)上,自主探索出兩位數(shù)加兩位(進位加)的計算方法,并通過交流、討論,達到對算法的優(yōu)化,在通過“試一試”、“算一算”、“想一想”等形式達到知識的掌握。
今天我說課的內(nèi)容是二年級上冊第二單元《100以內(nèi)的加法和減法》的第一課時,兩位數(shù)加兩位數(shù)的不進位加法。教材通過參觀博物館的情境圖引出兩位數(shù)的不進位和進位加法。本節(jié)課主要解決不進位加法豎式計算中的對位和計算順序問題。由于本節(jié)課是在學(xué)生已經(jīng)掌握兩位數(shù)加整十?dāng)?shù)、兩位數(shù)加一位數(shù)的基礎(chǔ)上學(xué)習(xí)的內(nèi)容,這堂課的關(guān)鍵是引導(dǎo)學(xué)生運用這些已有的知識經(jīng)驗,借助位值圖,通過自己的操作探究、合作學(xué)習(xí),將新知識轉(zhuǎn)化、納入已有的認知結(jié)構(gòu),自主地學(xué)習(xí)兩位數(shù)加兩位數(shù)不進位加法的計算方法。因此本節(jié)課的目標確定為:知識與能力:1、充分利用直觀手段,幫助學(xué)生理解和掌握筆算兩位數(shù)加兩位數(shù)的方法。2、培養(yǎng)學(xué)生觀察、分析、解決問題的能力。過程與方法:運用直觀手段,創(chuàng)設(shè)有意義的問題情境和游戲活動來組織教學(xué),讓學(xué)生通過動手操作、自主探索、合作交流等方法掌握算法,提高學(xué)習(xí)積極性,增強學(xué)習(xí)數(shù)學(xué)的興趣。
