一、教材的地位與作用 本節(jié)主要學(xué)習(xí)一元一次不等式組及其解集的概念,并要求學(xué)生會(huì)用數(shù)軸確定解集。它是一元一次不等式的后續(xù)學(xué)習(xí),也是一種基本的數(shù)學(xué)模型,也為下節(jié)和今后解決實(shí)際生產(chǎn)和生活問題奠定了堅(jiān)實(shí)的知識(shí)基礎(chǔ)。另外,整個(gè)學(xué)習(xí)的過程中數(shù)軸起著不可替代的作用,處處滲透著數(shù)形結(jié)合的思想,這種數(shù)學(xué)思想會(huì)一直影響著學(xué)生今后數(shù)學(xué)的學(xué)習(xí)。二、學(xué)情分析從學(xué)生學(xué)習(xí)的心理基礎(chǔ)和認(rèn)知特點(diǎn)來說,學(xué)生已經(jīng)學(xué)習(xí)了一元一次不等式,并能較熟練地解一元一次不等式,能將簡(jiǎn)單的實(shí)際問題抽象為數(shù)學(xué)模型,有一定的數(shù)學(xué)化歸能力。但學(xué)生將兩個(gè)一元一次不等式的解集在同一數(shù)軸上表示會(huì)產(chǎn)生一定的困惑。這個(gè)年齡段的學(xué)生,以感性認(rèn)識(shí)為主,并向理性認(rèn)知過渡,所以,本節(jié)課的設(shè)計(jì)是通過學(xué)生所熟悉的問題情境,讓學(xué)生獨(dú)立思考,合作交流,從而引導(dǎo)其自主學(xué)習(xí)。
(4)列式計(jì)算:94—34=60(個(gè))60—29=31(個(gè))或34+29=63(個(gè))94-63=31(個(gè))讓學(xué)生列出綜合算式,要他們正確的使用小括號(hào)。列好后要求學(xué)生說出每一步表示的意義。94-34-29或94-(34+29)b.教科書第7頁練習(xí)一的第3題。讓學(xué)生自己分析題目的已知條件和問題,然后用兩種方法列式解答。58-6-7或58-(6+7)[第2題和第3題是配合例2設(shè)計(jì)的。教學(xué)時(shí)先讓學(xué)生說明圖意,然后思考要解決的問題。著重練習(xí)如何正確使用小括號(hào),同時(shí)對(duì)學(xué)生進(jìn)行環(huán)保意識(shí)的教育。]9.作業(yè)安排①.新型電腦公司有87臺(tái)電腦,上午賣出19臺(tái),下午賣出26臺(tái),還剩下多少臺(tái)?(用兩種方法解答)②.班級(jí)里有22張臘光紙,又買來27張。開聯(lián)歡會(huì)時(shí)用去38張,還剩下多少?gòu)?③.少年宮新購(gòu)進(jìn)小提琴52把,中提琴比小提琴少20把,兩種琴一共有多少把?④.一輛公共汽車?yán)镉?6位乘客,到福州路下去8位,又上來12位,這時(shí)車上有多少位?
1、結(jié)合具體生活場(chǎng)景,能運(yùn)用所學(xué)的乘法口訣解決簡(jiǎn)單的實(shí)際問題,通過圖與式的對(duì)應(yīng),進(jìn)一步理解乘法的意義。 2、能熟練運(yùn)用口訣進(jìn)行計(jì)算,提高靈活運(yùn)用口訣解決實(shí)際問題的能力。 3、體會(huì)數(shù)學(xué)與實(shí)際生活的聯(lián)系,培養(yǎng)用數(shù)學(xué)的意識(shí),體驗(yàn)口訣在解決問題中的作用。 運(yùn)用所學(xué)乘法解決簡(jiǎn)單的實(shí)際問題。 結(jié)合實(shí)際情景理解乘法的意義。 1、口算: 5×2=10 6×2=12 8×5=40 2×7=14 5×9=45 3×5=15 2×6=12 2×9=18 4×2=8 2、談話導(dǎo)入:在前面的學(xué)習(xí)中,我們認(rèn)識(shí)了乘法,而且還學(xué)習(xí)了2和5的乘法口訣。這節(jié)課,老師想請(qǐng)同學(xué)們用這些跟乘法有關(guān)的知識(shí)來幫助老師一起解決生活中遇到的問題,一起來看一看吧??鞓沸菹r(shí)間到了,學(xué)校的大操場(chǎng)突然熱鬧起來了,你們一定非常喜歡課件活動(dòng)吧!看,操場(chǎng)上同學(xué)們有的在玩老鷹捉小雞的游戲,有的在進(jìn)行乒乓球比賽,有的在跳繩,還有的在踢毽子……真熱鬧?。?/p>
1、說課內(nèi)容:義務(wù)教育課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書數(shù)學(xué)(人教版)五年級(jí)下冊(cè)第69頁例1、例2。2、教材地位及作用:學(xué)生在三年級(jí)已初步認(rèn)識(shí)分?jǐn)?shù),但那時(shí)所學(xué)的分?jǐn)?shù)都是分子小于分母的分?jǐn)?shù),所以,學(xué)習(xí)這節(jié)內(nèi)容,使學(xué)生比較全面地理解分?jǐn)?shù)概念與培養(yǎng)對(duì)分?jǐn)?shù)的數(shù)感,起著重要的作用。3、教學(xué)目標(biāo)的確定:當(dāng)今時(shí)代是經(jīng)濟(jì)全球化,文化多元化,社會(huì)信息化的時(shí)代,所以教育也要追隨時(shí)代發(fā)展的步伐。遵循課標(biāo)提出的“為了每一位學(xué)生的發(fā)展”教育理念,確定本課教學(xué)目標(biāo)如下:①使學(xué)生理解真分?jǐn)?shù)和假分?jǐn)?shù)的意義;②通過學(xué)習(xí)真分?jǐn)?shù)、假分?jǐn)?shù),加深學(xué)生對(duì)分?jǐn)?shù)意義的理解;③使學(xué)生掌握真分?jǐn)?shù),假分?jǐn)?shù)的特征;④培養(yǎng)學(xué)生的觀察、比較、分析及概括的能力;⑤使學(xué)生在思考中、討論中,體會(huì)學(xué)習(xí)數(shù)學(xué)的快樂,體驗(yàn)成功的喜悅。4、教學(xué)重點(diǎn)、難點(diǎn):
教材分析異分母分?jǐn)?shù)加減法是第十冊(cè)第五單元的一個(gè)學(xué)習(xí)內(nèi)容。在這個(gè)內(nèi)容之前,學(xué)生已掌握了分?jǐn)?shù)的基本性質(zhì),學(xué)會(huì)了約分、通分、分?jǐn)?shù)小數(shù)互化的方法,懂得了同分母分?jǐn)?shù)加減法的算理,其中同分母分?jǐn)?shù)加減法的計(jì)算方法是本節(jié)課最直接的知識(shí)起點(diǎn)。本節(jié)課的內(nèi)容又是進(jìn)一步學(xué)習(xí)分?jǐn)?shù)加減法混合運(yùn)算的基礎(chǔ),同時(shí)又是本單元的重點(diǎn)。五年級(jí)學(xué)生已經(jīng)能理解只有分?jǐn)?shù)單位相同的分?jǐn)?shù)才能相加減的算理,并且已經(jīng)初步具有用舊知識(shí)解決新問題的能力,也就是具有了一定的知識(shí)遷移能力。教學(xué)目標(biāo):1、理解異分母分?jǐn)?shù)加減法的算理,并能正確計(jì)算。2、運(yùn)用類比遷移的方法探索新知,培養(yǎng)推理能力和概括能力。3、滲透轉(zhuǎn)化的數(shù)學(xué)思想,體驗(yàn)數(shù)學(xué)知識(shí)的探索性。教學(xué)重點(diǎn):掌握異分母分?jǐn)?shù)加減法的計(jì)算方法。教學(xué)難點(diǎn):理解先通分,再加減的算理。教學(xué)流程:一、鋪墊。
3.第三個(gè)環(huán)節(jié)是:鞏固深化,應(yīng)用新知。首先讓學(xué)生完成課本76頁練習(xí)十三的第一題。主要是檢驗(yàn)學(xué)生對(duì)復(fù)式折線統(tǒng)計(jì)圖繪制方法的掌握情況,并能對(duì)復(fù)式折線統(tǒng)計(jì)圖所表達(dá)的信息進(jìn)行簡(jiǎn)單的分析、比較。練習(xí)時(shí),先讓學(xué)生在書上獨(dú)立完成,再說一說制圖的正確步驟,我用多媒體演示,并提醒學(xué)生注意最高氣溫和最低氣溫對(duì)應(yīng)的折線各用什么表示,還要寫上數(shù)據(jù)和制圖日期,根據(jù)學(xué)生的制作情況,還可以組織學(xué)生討論一下,兩條折線上的數(shù)據(jù)怎樣寫就不混淆了?最后讓學(xué)生看圖回答題中的問題,這里重點(diǎn)幫助學(xué)生弄清“溫差”的含義,另外,在回答最后一個(gè)問題時(shí),學(xué)生可能會(huì)說“我喜歡看統(tǒng)計(jì)圖”,我就重點(diǎn)讓學(xué)生說說為什么喜歡看統(tǒng)計(jì)圖?從而讓學(xué)生進(jìn)一步體會(huì)復(fù)式折線統(tǒng)計(jì)圖的直觀、形象的優(yōu)越性
1、完成練習(xí)十五第1題。(1)學(xué)生獨(dú)立完成計(jì)算。(2)指名板演,交流計(jì)算方法。提問:你是按照什么運(yùn)算順序計(jì)算的?指出:分?jǐn)?shù)加減混合運(yùn)算的運(yùn)算順序與整數(shù)相同,參與運(yùn)算的幾個(gè)分?jǐn)?shù),可以分步通分,分步計(jì)算;也可以一次通分,再計(jì)算。計(jì)算結(jié)果要約成最簡(jiǎn)分?jǐn)?shù)。[練習(xí)十五里異分母分?jǐn)?shù)加減混合運(yùn)算的純計(jì)算題比較少,僅第1題里有4道。教學(xué)中適當(dāng)補(bǔ)充三個(gè)分?jǐn)?shù)加減混合運(yùn)算的練習(xí)也是可以的,但不要耗費(fèi)學(xué)生過多的學(xué)習(xí)精力。如果學(xué)生計(jì)算發(fā)生錯(cuò)誤,要仔細(xì)分析原因,有針對(duì)性地采取有效的解決措施。]2、完成練習(xí)十五第2題。(1)讀題,理解題意,說說自己的思路。(2)學(xué)生獨(dú)立完成解答。10(3)+ 5(1)+ 6(1)= 30(9)+ 30(6)+ 30(5)= 30(20)= 3(2)(小時(shí))(3)交流匯報(bào),集體評(píng)價(jià)。3、完成練習(xí)十五第3題。(1)學(xué)生獨(dú)立完成(1)、(2)小題,說說自己是怎樣想的?(2)鼓勵(lì)學(xué)生根據(jù)題中的已知條件提出用分?jǐn)?shù)加、減法計(jì)算的不同問題,可以是一步計(jì)算的,也可以是兩步計(jì)算的,并讓學(xué)生嘗試解決提出的一些問題。
例1用為每個(gè)小朋友準(zhǔn)備春游食品的活動(dòng),由“應(yīng)該每份同樣多”引出“平均分”,讓學(xué)生認(rèn)識(shí)“每份分得同樣多,叫平均分”。接著,通過例2、例3,讓學(xué)生經(jīng)歷“平均分”的過程,建立起“平均分”的概念。二、說教學(xué)目標(biāo)二年級(jí)學(xué)生年齡小,他們以直觀思維為主,不易理解抽象的概念。雖然他們?cè)谄綍r(shí)的生活實(shí)踐中已有一定的分物品的經(jīng)驗(yàn),但缺少平均分物品的實(shí)踐經(jīng)驗(yàn)。因此,他們對(duì)于“什么是平均分”,“怎樣平均分物品”都感到比較困惑。所以,本節(jié)課的教學(xué)目標(biāo)可以預(yù)設(shè)為:1.引導(dǎo)學(xué)生在具體情境中感受“平均分”,在分東西的實(shí)踐活動(dòng)中建立“平均分”的概念,理解“平均分”的含義。2.讓學(xué)生經(jīng)歷“平均分”的過程,在具體情境與實(shí)踐活動(dòng)中明確“平均分”的含義,掌握“平均分”物品的不同方法。3.培養(yǎng)學(xué)生自主探究的意識(shí)和解決問題的能力。
【設(shè)計(jì)意圖:這是為例4的教學(xué)而設(shè)計(jì)的情境,起過渡作用,使學(xué)生明確通分的重要性,同時(shí)能促進(jìn)學(xué)生的學(xué)習(xí)積極性、主動(dòng)性?!浚ǘ┏鍪緦W(xué)習(xí)目標(biāo):(1)教學(xué)例3第一層:嘗試做例3,讓學(xué)生獨(dú)立探究,運(yùn)用舊知識(shí)去解決新問題。教師針對(duì)這一問題,啟發(fā)點(diǎn)撥:這兩個(gè)分?jǐn)?shù)能直接比較大小嗎?那么,能不能借助一些學(xué)過的知識(shí),設(shè)法把這兩個(gè)分?jǐn)?shù)化為能直接比較的分?jǐn)?shù),再比較出它們的大小呢?學(xué)生:獨(dú)立探究,小組交流,全班匯報(bào)?!驹O(shè)計(jì)意圖:讓學(xué)生獨(dú)立嘗試探究,初步感知通分】第二層:看書自學(xué)例3,并出示自學(xué) 要求:1.書上是如何比較 和大小的?(動(dòng)筆寫一寫) 2.什么叫公分母?3.什么叫通分?質(zhì)疑問難:“通過你們自學(xué)例3,還有什么疑問嗎?”“找兩個(gè)分?jǐn)?shù)的公分母,為什么要找4和6的最小公倍數(shù)呢?”【設(shè)計(jì)意圖:通過自學(xué)理解什么是“公分母”和“通分”,使學(xué)生對(duì)新概念有一個(gè)自我內(nèi)化的過程】
在此基礎(chǔ)上教師又適時(shí)提出問題“根據(jù)你擺的飛機(jī),誰能提個(gè)問題讓大家猜一猜?”學(xué)生興趣盎然,提出了諸如“我用10根小棒擺幾架飛機(jī)”的問題,由此引出“求一個(gè)數(shù)里含有幾個(gè)另一個(gè)數(shù)的除法含義”,為學(xué)習(xí)“一個(gè)數(shù)是另一個(gè)數(shù)的幾倍”奠定了基礎(chǔ)。在學(xué)生動(dòng)手操作、動(dòng)眼觀察的基礎(chǔ)上,課件出示例題中小強(qiáng)提出的問題:“我擺了3架飛機(jī),我用的小棒根數(shù)是小紅的幾倍?”怎么解決這個(gè)問題呢?我請(qǐng)學(xué)生在小組里討論,在動(dòng)腦思考、充分探究中找到了“求一個(gè)數(shù)是另一個(gè)數(shù)的幾倍是多少”的解題思路,即“求一個(gè)數(shù)是另一個(gè)數(shù)的幾倍”的含義,就是“求一個(gè)數(shù)里含有幾個(gè)另一個(gè)數(shù)”,用除法計(jì)算,15÷5=3。在這樣的教學(xué)活動(dòng)中,學(xué)生經(jīng)歷了解決問題的過程,學(xué)會(huì)了用數(shù)學(xué)的思維方式去觀察、分析實(shí)際問題,學(xué)會(huì)了從數(shù)學(xué)的角度提出問題、理解問題、解決問題,培養(yǎng)了綜合運(yùn)用所學(xué)知識(shí)解決實(shí)際問題的能力。
2、81頁的做一做。做完后,引導(dǎo)學(xué)生觀察4和8;16和32這一組的最大公因數(shù)的特點(diǎn):當(dāng)較大數(shù)是較小數(shù)的倍數(shù)時(shí),他們的最大公因數(shù)是較小數(shù)。1和7;8和9這一組數(shù)的最大公因數(shù)只有1。這樣的練習(xí)設(shè)計(jì),目的是讓學(xué)生發(fā)現(xiàn)求最大公因數(shù)中的特殊情況。四、遷移運(yùn)用,拓展探究寫出下列各分?jǐn)?shù)分子和分母的最大公因數(shù)。7/21 8/28 16/40 6/15 目的是為下一節(jié)課《約分》做好了知識(shí)的鋪墊。全課總結(jié):通過今天的學(xué)習(xí),你有什么收獲?同桌互說,指名匯報(bào)。這樣的總結(jié),從知識(shí)的層面上做了一次回顧。并及時(shí)的總結(jié)了解學(xué)情,真正做到“堂堂清”五、說板書設(shè)計(jì)我本節(jié)課的板書設(shè)計(jì)力圖全面而簡(jiǎn)明的將本課的內(nèi)容傳遞給學(xué)生,便于學(xué)生理解和記憶。各位評(píng)委老師,我僅從教材、教法、學(xué)法、及教學(xué)過程、板書設(shè)計(jì)等幾個(gè)方面對(duì)本課進(jìn)行說明。這只是我預(yù)設(shè)的一種方案,但是課堂千變?nèi)f化的生成效果,最終還要和學(xué)生、課堂相結(jié)合。說課的不足之處還請(qǐng)多多指教,我的說課到此結(jié)束,謝謝各位評(píng)委老師。
區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句,都叫做主從復(fù)合句。賓語從句主要是中考必考的,是初中階段必掌握的從句,賓語從句主要是掌握三要素,所謂賓語從句,就是賓語在主從復(fù)合句當(dāng)中充當(dāng)賓語的一個(gè)句子,叫做賓語從句。主句的謂語動(dòng)詞是及物動(dòng)詞,后面如果是詞或者是短語的話,是簡(jiǎn)單句,如果是句子的話,肯定是賓語從句。I know that he good at English.就是賓語從句,三要素,一要素是要注意連詞,連詞一共學(xué)了三類連詞,一類連詞是that口語當(dāng)中可以省略,就像剛才說的那一句,I hear he is good at English.還有疑問代詞、疑問副詞,how where when,疑問代詞、疑問副詞。還有一類連詞weather是否的意思,不是狀語從句當(dāng)中的如果,這一定要和如果區(qū)分開,這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序,要用陳述舉語序。比如說你家有幾口人,我們都說How many people are there in you family?但是這是簡(jiǎn)單句,一旦說成賓語從句,你可以告訴我你家有幾口人嗎?Could you tell me how many people there are in you family ?

"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it?
