教學(xué)內(nèi)容:課本P104、108頁(yè)。教學(xué)目標(biāo):1、通過(guò)復(fù)習(xí)使學(xué)生加深了解統(tǒng)計(jì)的意義。2、鞏固學(xué)生對(duì)條形統(tǒng)計(jì)圖的認(rèn)知,明確用1格表示2個(gè)單位的表現(xiàn)形式,能根據(jù)統(tǒng)計(jì)圖提出問(wèn)題。3、在學(xué)習(xí)過(guò)程中培養(yǎng)學(xué)生的實(shí)踐能力與合作意識(shí)。教學(xué)重點(diǎn)、難點(diǎn):1、在復(fù)習(xí)中進(jìn)一步了解統(tǒng)計(jì)的意義,加深對(duì)條形統(tǒng)計(jì)圖的認(rèn)識(shí)。2、能根據(jù)條形統(tǒng)計(jì)圖的條件提出數(shù)學(xué)問(wèn)題。教學(xué)過(guò)程:一、復(fù)習(xí)統(tǒng)計(jì)1、觀察討論(1)、教師出示條形統(tǒng)計(jì)圖:這張圖叫什么名字?它有什么作用?仔細(xì)觀察統(tǒng)計(jì)圖你有哪些發(fā)現(xiàn)?(2)、學(xué)生觀察討論,思考,依據(jù)自己的體驗(yàn)回答。仔細(xì)觀察統(tǒng)計(jì)圖,在小組內(nèi)交流自己的發(fā)現(xiàn)。(3)、組織全班匯報(bào)交流,梳理統(tǒng)計(jì)圖信息。2、回答問(wèn)題根據(jù)條形統(tǒng)計(jì)圖上的信息,你能回答下列問(wèn)題嗎?1)、最受二年級(jí)同學(xué)歡迎的飲料是什么?你是怎么看出來(lái)的?2)、喜歡哪兩種飲料的人數(shù)同樣多?你是怎么知道的?
(4)學(xué)校買(mǎi)10套課桌用500元,已知桌子的單價(jià)是凳子的4倍,每張桌子多少元?三、作業(yè)。第四課時(shí)課題:可能性和編碼復(fù)習(xí)目標(biāo):1、認(rèn)識(shí)簡(jiǎn)單的可能性事件。2、會(huì)求簡(jiǎn)單事件發(fā)生的可能性,并用分?jǐn)?shù)表示。3、通過(guò)日常生活中的一些事例,使學(xué)生初步體會(huì)數(shù)字編碼思想在解決實(shí)際問(wèn)題中的應(yīng)用。4、讓學(xué)生學(xué)會(huì)運(yùn)用數(shù)進(jìn)行編碼,初步培養(yǎng)學(xué)生的抽象、概括能力。一、基本練習(xí)。1、盒子中有紅、白、黃、綠四種顏色的球各一個(gè),只取一次,拿出紅色球的可能性是多少?白色呢?2、商場(chǎng)促銷,將獎(jiǎng)品放置于1到10號(hào)的罐子里,幸運(yùn)顧客有一次猜獎(jiǎng)機(jī)會(huì),一位顧客猜中得獎(jiǎng)的可能性是多少?3、盒子中有紅色球8個(gè),藍(lán)色球10個(gè),取一次,取出紅色球的可能性大還是藍(lán)色球?4、說(shuō)出下面各組數(shù)據(jù)的中位數(shù)。
五、教學(xué)反思:時(shí)鐘的秒針、分針、時(shí)針掃的圖形, 汽車擋風(fēng)玻璃的刮水器;刷工人刷過(guò)的面積近似看為扇形。圓中的計(jì)算問(wèn)題---弧長(zhǎng)和扇形的面積,雖然新課標(biāo)、新教材要求學(xué)習(xí),但本節(jié)教師結(jié)合學(xué)生的實(shí)際要求,將其作為內(nèi)容進(jìn)行拓展與延伸,具有一定的實(shí)際意義。用生活中動(dòng)態(tài)幾何解釋扇形,體驗(yàn)解決問(wèn)題策略的多樣性,發(fā)展實(shí)踐能力與創(chuàng)新精神。本節(jié)課,教師通過(guò)“扇子”的問(wèn)題情景引入新課,它蘊(yùn)含了大量的情感信息,有效激發(fā)學(xué)生的求知欲望,充分調(diào)動(dòng)學(xué)生的學(xué)習(xí)積極性,注重學(xué)生的參與,讓出時(shí)間與空間由學(xué)生動(dòng)手實(shí)踐,鼓勵(lì)學(xué)生自主探索、合作交流、展示成果,提高了學(xué)生發(fā)現(xiàn)問(wèn)題、提出問(wèn)題、解決問(wèn)題的能力。用“扇子變化”,幫助學(xué)生探索自然界中事物的動(dòng)靜結(jié)合問(wèn)題,利用“扇子的文化”的新奇感激起學(xué)生的學(xué)習(xí)熱情,陶冶了學(xué)生的學(xué)習(xí)情操,從而使學(xué)生更深切地理解問(wèn)題,使原本單調(diào)枯燥的數(shù)學(xué)變得生動(dòng)、形象,激發(fā)學(xué)生的情感,使課堂充滿生機(jī)。
【設(shè)計(jì)意圖】學(xué)習(xí)事理說(shuō)明文,要讓學(xué)生在自主歸納的過(guò)程中,初步感知事理說(shuō)明文說(shuō)明“事理”這一基本特點(diǎn),把握事理說(shuō)明文和事物說(shuō)明文的不同之處。引導(dǎo)學(xué)生通過(guò)學(xué)習(xí)課文,對(duì)科學(xué)方法產(chǎn)生自己的體會(huì),并運(yùn)用到自己的思考中。四、總結(jié)存儲(chǔ)1.教師小結(jié)本文是一篇事理說(shuō)明文,作者把一門(mén)科學(xué)——物候?qū)W介紹得淺顯易懂,饒有趣味。全文采用邏輯順序說(shuō)明,思路清晰明了:描述物候現(xiàn)象——做出科學(xué)解釋——追究因果關(guān)系——闡述研究意義。這種從現(xiàn)象到本質(zhì)的認(rèn)識(shí)方法和行文思路值得我們學(xué)習(xí)。本文語(yǔ)言嚴(yán)謹(jǐn)而生動(dòng),兼具說(shuō)明的科學(xué)性和生動(dòng)性,是一篇極有價(jià)值的科普文,是科學(xué)家竺可楨科學(xué)精神和科學(xué)思想的具體體現(xiàn)。文章啟發(fā)我們:科學(xué)距離我們并不遙遠(yuǎn),就在我們的身邊,而想要探索它,就要有科學(xué)精神,擴(kuò)大科學(xué)知識(shí)儲(chǔ)備,掌握科學(xué)方法,勇于探索科學(xué)奧秘。
結(jié)束這節(jié)課,我心里很輕松,因?yàn)樵谝酝慕虒W(xué)中學(xué)生感覺(jué)到:說(shuō)明文很單調(diào)、枯燥不生動(dòng)。而本節(jié)課學(xué)生與我配合得非常好,原因是我利用多媒體展示的幾幅畫(huà)面,把學(xué)生的注意力都集中在所講的內(nèi)容中,并且調(diào)動(dòng)了學(xué)生學(xué)習(xí)的積極性,認(rèn)為物候現(xiàn)象就在我們的身邊,激發(fā)學(xué)生探索科學(xué)奧秘的興趣,更多地去了解大自然,認(rèn)識(shí)大自然,熱愛(ài)大自然。在初讀課文的時(shí)候,我訓(xùn)練了學(xué)生的概括能力;在分清舉例說(shuō)明的方法時(shí),讓學(xué)生明白什么是舉例子的說(shuō)明方法;在細(xì)讀課文的時(shí)候,讓學(xué)生學(xué)習(xí)生動(dòng)地有條理地說(shuō)明事物的方法,還重點(diǎn)品味第一段的生動(dòng)語(yǔ)言,在品味說(shuō)明文語(yǔ)言的準(zhǔn)確性時(shí),有日常生活中的例子導(dǎo)入,深入淺出地講解了說(shuō)明語(yǔ)言準(zhǔn)確性的兩點(diǎn)情況。
教后反思本節(jié)課給學(xué)生創(chuàng)設(shè)了良好的活動(dòng)空間,把學(xué)生實(shí)際生活中聽(tīng)說(shuō)過(guò)的見(jiàn)到的平均分現(xiàn)象展示給學(xué)生看,把生活和數(shù)學(xué)聯(lián)系起來(lái),在學(xué)生感受“同樣多”的基礎(chǔ)上概括出什么叫平均分。揭示平均分這一數(shù)學(xué)知識(shí)在生活中的應(yīng)用,之后突出了學(xué)生三次實(shí)際操作。第一次,小組同學(xué)互相分水果,重視學(xué)生分的結(jié)果。體會(huì)感受“平均分”的含義。第二次,重視分法:15個(gè)橘子平均分成5份。體現(xiàn)了學(xué)生對(duì)物品的不同分法,建立了平均分的概念。第三次,分礦泉水,通過(guò)份數(shù)變化,觀察分的就結(jié)果,深刻體會(huì)“平均分”,為認(rèn)識(shí)除法積累豐富的知識(shí)。為學(xué)生營(yíng)造探索的空間。第二課時(shí):平均分的認(rèn)識(shí)(二)教學(xué)內(nèi)容鞏固“平均分”。課本第15頁(yè)的例題3。教學(xué)目標(biāo)1.鞏固“平均分”的概念,知道平均分就是每一份分得結(jié)果同樣多。
三維目標(biāo)1.知識(shí)與技能(1)讓學(xué)生經(jīng)歷用7、8、9的乘法口訣求商的過(guò)程,掌握用乘法口訣求商的一般方法。(2)使學(xué)生會(huì)綜合應(yīng)用乘、除法運(yùn)算解決簡(jiǎn)單的或稍復(fù)雜的實(shí)際問(wèn)題。2.過(guò)程與方法在解決問(wèn)題的過(guò)程中,讓學(xué)生初步嘗試運(yùn)用分析、推理和轉(zhuǎn)化的學(xué)習(xí)方法。3.情感、態(tài)度與價(jià)值觀讓學(xué)生在學(xué)習(xí)中體驗(yàn)到成功的喜悅,增強(qiáng)學(xué)生學(xué)好數(shù)學(xué)的信心。重、難點(diǎn)與關(guān)鍵1.重點(diǎn):使學(xué)生熟練應(yīng)用乘法口訣求商,經(jīng)歷從實(shí)際問(wèn)題中抽象出一個(gè)數(shù)是另一個(gè)數(shù)的幾倍的數(shù)量關(guān)系的過(guò)程,會(huì)用乘法口訣求商的技能解決實(shí)際問(wèn)題。2.難點(diǎn):應(yīng)用分析推理將一個(gè)數(shù)是另一個(gè)數(shù)的幾倍是多少的數(shù)量關(guān)系轉(zhuǎn)化為一個(gè)數(shù)里面有幾個(gè)另一個(gè)數(shù)的除法含義。3.關(guān)鍵:以解決問(wèn)題為載體,培養(yǎng)學(xué)生的數(shù)感。
所需要用到的句子:Who is that?That is Jack. I like him.Why do you like him?I like him because he is interesting.Task 4: 設(shè)計(jì)理想中的人類Step one: 設(shè)計(jì)理想中的人類的外貌。把全班同學(xué)分成若干小組,學(xué)生可以邊說(shuō)邊在紙上畫(huà)出他們的模樣。Step two: 設(shè)計(jì)理想中人類的性格。學(xué)生們可以把那些能描述性格的單詞寫(xiě)在圖畫(huà)的旁邊。Step three: 每組選出一名同學(xué),其他同組同學(xué)提問(wèn),他作簡(jiǎn)單回答,并說(shuō)明原因。所需用到的句子:What does he or she look like?He or she ...What is he or she like?He or she is ...Why?Because ...Task 5: 挑戰(zhàn)性活動(dòng)調(diào)查性格是天生的還是后天形成的,讓每個(gè)同學(xué)回家去調(diào)查一下自己成長(zhǎng)過(guò)程中性格是否有變化,具體是怎樣的,為什么會(huì)這樣? Teaching Aims:1. Enable students to have a general understanding of how to talk about people's physical appearance.2. Enable students to tackle some essential vocabularies and patterns about describing people. Provide them with necessary skills and methods.3. Create various chances for students to describe the persons they're familiar with, such as classmates, family members, teachers, idols, etc.

單元整體說(shuō)明(一)單元教材分析本單元的核心話題是描述動(dòng)物和表達(dá)個(gè)人喜好,以及句式why do you like…? Because…。這也是本單元的教學(xué)重點(diǎn)。通過(guò)本單元的學(xué)習(xí),學(xué)生應(yīng)能較流利地運(yùn)用所學(xué)詞匯和句型描述動(dòng)物,表達(dá)個(gè)人喜好。(二)單元知識(shí)結(jié)構(gòu)1.詞匯動(dòng)物名稱 tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國(guó)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(biāo)1.Master the vocabulary2.Master and use: Why do you like koalas?

雖然在此之前已經(jīng)聽(tīng)過(guò)多節(jié)有關(guān)的研討課,但臨到自己教學(xué)時(shí)才真正體會(huì)到本課教學(xué)的艱難。一是信息化時(shí)代對(duì)郵政編碼的沖突。其實(shí)我在教學(xué)前也僅僅只知道學(xué)校和家庭住址的郵編,至于郵政編碼的結(jié)構(gòu)含義等是完全陌生。在課堂前測(cè)中了解到,全班僅3人有寫(xiě)信寄信的經(jīng)歷(這三名學(xué)生的老家都遠(yuǎn)離湖北?。?,他們知道老家的郵編,全班有半數(shù)左右的家庭收集不到已經(jīng)郵寄過(guò)的舊信封。可以說(shuō)在學(xué)習(xí)本課前師生對(duì)郵政編碼都是知之甚少,教師本身都只“半勺水”,何以給學(xué)生“一杯水”?雖然在課前布置學(xué)生收集了一些有關(guān)郵政編碼的知識(shí),自己也進(jìn)行了大量的查詢,但在實(shí)際教學(xué)中仍舊倍感吃力。如有學(xué)生質(zhì)疑“為什么書(shū)上北京人民出版社的郵編是100008,它的第三、四位都是0呢”;“為什么我們學(xué)校的郵編4300XX第三、四位也是0呢”;“郵區(qū)是不是指什么市?”“郵區(qū)與市、區(qū)、縣有什么關(guān)系?”一個(gè)接一個(gè)問(wèn)題“炮轟”過(guò)來(lái),著實(shí)招架不住。
