(三)、歷史的必然:人民代表大會制度的確立1、《中國人民政治協(xié)商會議共同綱領(lǐng)》作為臨時憲法規(guī)定我國根本政治制度是人民代表大會制度。新中國的成立,標(biāo)志著億萬中國人民真正成為國家、社會和自己命運的主人。此前召開的中國人民政治協(xié)商會議第一屆全體會議,為建立新型國家政權(quán)發(fā)揮了重大作用,會議通過的《中國人民政治協(xié)商會議共同綱領(lǐng)》具有臨時憲法的地位,為全國人民代表大會制度的建立奠定了法律基礎(chǔ)。共同綱領(lǐng)規(guī)定:中華人民共和國的國家政權(quán)屬于人民,人民行使國家權(quán)力的機關(guān)為各級人民代表大會和各級人民政府。2、人民代表大會制度在我國正式建立起來的標(biāo)志:1954年9月15日,第一屆全國人民代表大會第一次會議在北京召開,會議通過了《中華人民共和國憲法》,標(biāo)志著人民代表大會制度在我國正式建立起來。
◇本框題小結(jié):◇3個體現(xiàn):即人民代表大會制度是我國的根本政治制度的3個體現(xiàn)(1)、人民代表大會制度決定著國家的其他各種具體制度;(2)、人民代表大會制度是中國人民當(dāng)家作主的最高形式和重要途徑;(3)、人民代表大會制度是中國社會主義政治文明的重要制度載體。◇3個表現(xiàn):即民主集中制確保國家權(quán)力協(xié)調(diào)高效的表現(xiàn):(1)、從人民代表大會和人民的關(guān)系來看①各級人民代表受選民和原選舉單位的監(jiān)督,選民或選舉單位有權(quán)罷免自己選舉出的代表;②各級人民代表大會代表人民統(tǒng)一行使國家權(quán)力(2)、從人民代表大會與其他國家機關(guān)的關(guān)系來看①其他國家機關(guān)都由人民代表大會產(chǎn)生,對它負責(zé)、受它監(jiān)督;②在人民代表大會統(tǒng)一行使國家權(quán)力的前提下,其他國家機關(guān)依照法定分工依法行使各自的職權(quán)。(3)、從中央和地方的關(guān)系來看①地方必須服從中央;②在保證中央統(tǒng)一領(lǐng)導(dǎo)的同時,必須考慮地方特殊利益,充分發(fā)揮地方的主動性和積極性。
出示例6掛圖。教師試問:誰知道0.50元是幾角?2.00元是幾角?你是怎么知道?以元為單位小數(shù)點左邊是幾就是幾元,右邊第一位是幾就是幾角,右邊第二位是幾就是幾分。1.20元是1元2角。35.90元是35元9角。(這部分知識學(xué)生知道它表示幾元幾角就可以了,至于1.20元是個什么數(shù),怎么讀、寫不需要學(xué)生掌握)3、教學(xué)例7。(1) 課件演示例7第一小題。教師:0.5元是幾角?(5角)0.80元是幾角?(8角)學(xué)生回答。5角+8角是幾角?(5角+8角=13角教師板書)教師問:多少角是1元?13角里面拿出10角還剩多少角?(3角)所以13角等于1元3角。教師板書:5角+8角=13角=1元3角。(2)例7第二小題(課件演示,提出問題:我買這兩個氣球要多少錢)學(xué)生嘗試完成,然后提問:你是怎么想的?教師強調(diào):元、角計算,只有在相同單位的情況下,才能相加。

教學(xué)內(nèi)容:口算乘法教學(xué)目標(biāo):使學(xué)生加深對乘法含義的理解,讓學(xué)生知道生活中處處有乘法。教學(xué)重點:通過觀察能熟練用乘法問題。教學(xué)過程:一、復(fù)習(xí)。6×48×59×77×56×89×7二、結(jié)合生活情況使學(xué)生加深體會乘法的含義。1、教學(xué)p68的主題圖。(1)、讓學(xué)生獨立觀察教科書p68中情境圖。思考:①、這幅畫面是什么地方?②、你發(fā)現(xiàn)了畫面中有什么游戲項目。(2)、在小組中互相說說自己觀察到了什么內(nèi)容。(3)、各小組代表匯報。(4)、教師板書學(xué)生匯報的數(shù)據(jù)。(5)、師:根據(jù)你們提供的信息(條件),你能提出用乘法計算的問題嗎?大家在小組里議一議。2、感知生活中有乘法。(1)、學(xué)生匯報。(略)(2)、師:這些活動,你們在哪親身體驗過呢?3、體會生活中的數(shù)學(xué)問題。師:除以上這些數(shù)學(xué)問題,你們誰還能提出其他的數(shù)學(xué)問題,并使用乘法計算?學(xué)生通過思考,自由回答。
一、揭題:小朋友們,今天我們一起來做練習(xí)。二、練習(xí):1、第8題:這是一道計算題。(1)明確要求:看誰算得又對又快。(2)學(xué)生獨立完成。(3)訂正答案。(4)有錯的學(xué)生,說一說計算順序是怎樣的,每一步的計算結(jié)果是多少?2、第9題:這是一道用數(shù)學(xué)的題。(1)看圖,同位兩個互相說說圖意,并提出數(shù)學(xué)問題。(2)根據(jù)問題列算式解答。(3)訂正答案。3、第10題:比一比。(1)明確要求,看誰先奪得紅旗。(2)各小組派代表參加比賽。(3)對算得又對又快的學(xué)生提出表揚,并獎勵給一個小標(biāo)志。(4)再加入幾組比賽題,盡量讓學(xué)生多參與。4、第11題:這是一道用數(shù)學(xué)的題。(1)看圖,說圖意,提出數(shù)學(xué)問題。(2)列算式解答,指名板演訂正。(3)說一說為什么用加法計算?5、思考題:小組討論完成。一共12人,每兩人之間插入一個女生,一共能插入11人。
1、找一找 (計算機演示圖意)2、師:星期天,小江想到小明家去玩,可他只記得小明家住在三樓的左邊,你們能告訴他小明家住幾號房嗎?(展開討論,計算機學(xué)示結(jié)果)2、想一想師:我跟大家面對面地站著(老師舉起右手),請問:老師舉起的是右手嗎?師:(老師把右手放下)請小朋友把右手舉起來再判定一下老師舉起的是不是右手。(老師又舉起右手)學(xué)生討論老師舉著右手轉(zhuǎn)身與學(xué)生同向,證實結(jié)論。師:我們面對面地站著,因為方向相對,舉的右手就會剛好相反。練習(xí):老師和學(xué)生一同舉左手體驗。四、 解決問題,增強應(yīng)用意識1、說一說:你相鄰的同桌都有誰?問:相鄰是什么意思?面對黑板說說你相鄰的同學(xué)有誰?背對黑板說說你相鄰的同學(xué)有誰?側(cè)轉(zhuǎn)身再說說你相鄰的同學(xué)有誰?師:每轉(zhuǎn)一次前、后、左、右的人都發(fā)生了變化,但相鄰的同學(xué)總是這幾個。2、用電腦演示同學(xué)們上下樓梯的情景
3、同學(xué)們,你們看今天老師帶來了什么?(出示一個學(xué)生喜歡的玩具)這是昨天老師去商店時買的,猜猜看,這個需要多少錢?(學(xué)生猜,教師可提示,最后得出正確標(biāo)價)今天我們也來開個小小商店玩一玩買賣商品的游戲,想玩嗎?4、選營業(yè)員及經(jīng)理。我覺得當(dāng)營業(yè)員最重要的是精通業(yè)務(wù),計算能力強。誰想來當(dāng)?(等學(xué)生舉手后,教師選出4人。)考慮到我們呆會兒買的人會比較多,每個柜臺一個營業(yè)員忙不過來,我還準(zhǔn)備再選4名商店經(jīng)理,做好以下幾項工作:1)做好接待服務(wù)工作,顧客有困難能主動幫助。2)做好買賣過程中的組織工作,讓大家有秩序地買商品。3)當(dāng)營業(yè)員計算碰到困難時,兩人能商量著解決。覺得自己能做到以上三點的同學(xué)可舉手參加競選。(學(xué)生舉手后,選出4名經(jīng)理)
教后反思本節(jié)課給學(xué)生創(chuàng)設(shè)了良好的活動空間,把學(xué)生實際生活中聽說過的見到的平均分現(xiàn)象展示給學(xué)生看,把生活和數(shù)學(xué)聯(lián)系起來,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)知識在生活中的應(yīng)用,之后突出了學(xué)生三次實際操作。第一次,小組同學(xué)互相分水果,重視學(xué)生分的結(jié)果。體會感受“平均分”的含義。第二次,重視分法:15個橘子平均分成5份。體現(xiàn)了學(xué)生對物品的不同分法,建立了平均分的概念。第三次,分礦泉水,通過份數(shù)變化,觀察分的就結(jié)果,深刻體會“平均分”,為認識除法積累豐富的知識。為學(xué)生營造探索的空間。第二課時:平均分的認識(二)教學(xué)內(nèi)容鞏固“平均分”。課本第15頁的例題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。
3.小結(jié)。引導(dǎo)學(xué)生歸納兩位數(shù)加減法的口算步驟:要把加上或減去的兩位數(shù)看成一個整十?dāng)?shù)和一個一位數(shù),先算兩位數(shù)加、減整十?dāng)?shù),再算兩位數(shù)加減一位數(shù)。三、鞏固練習(xí)課本第93頁的做一做。分別指名口算,并說說怎么想的。四、全課總結(jié)1.根據(jù)學(xué)生回答,教師歸納小結(jié)并出示課題:口算兩位數(shù)加、減兩位數(shù)。2.口算兩位數(shù)加、減兩位數(shù)應(yīng)注意什么?五、布置作業(yè)教后反思《標(biāo)準(zhǔn)》提倡算法多樣化,目的是提倡學(xué)生個性化的學(xué)習(xí)。本單元仍然注意體現(xiàn)這一理念,如本課時教學(xué)口算兩位數(shù)加、減兩位數(shù)時,既呈現(xiàn)了口算方法,還出現(xiàn)了在腦中想豎式的方法;在教學(xué)筆算時,還出現(xiàn)口算的方法。其目的就是鼓勵學(xué)生展開思路,在交流、比較的基礎(chǔ)上不斷地完善自己的想法,學(xué)習(xí)計算方法。
2、揭題:小朋友們,知道嗎?剛才你們的學(xué)習(xí)過程其實就是統(tǒng)計的過程,這節(jié)課我們就一起來研究統(tǒng)計的有關(guān)知識。3、發(fā)統(tǒng)計圖和統(tǒng)計表:根據(jù)你剛才收集的數(shù)據(jù),完成統(tǒng)計圖和統(tǒng)計表。實踐活動(調(diào)查全班小朋友們喜歡的動物)統(tǒng)計表:(學(xué)具卡片)綠孔雀非洲象大熊貓袋鼠梅花鹿河馬統(tǒng)計圖:(學(xué)具卡片)綠孔雀非洲象大熊貓袋鼠梅花鹿河馬4、出示統(tǒng)計圖和統(tǒng)計表。(1)通過小朋友們的統(tǒng)計,你能發(fā)現(xiàn)什么?(2)你可以提出什么問題?三、總結(jié):1、日常生活中有許多事情可以用統(tǒng)計解決,你能說一說嗎?2、談?wù)勥@節(jié)課你的收獲。作業(yè)布置:第二課時、練習(xí)教學(xué)內(nèi)容:完成練習(xí)十七的2——4題。教學(xué)目標(biāo):鞏固本單元所學(xué)的內(nèi)容。教學(xué)過程:一、檢查作業(yè):1、小組互相交流自己調(diào)查的結(jié)果。2、展示幾份。二、練習(xí):練習(xí)十七1、第2題。(1)看圖,明確題意。(2)先用自己喜歡的方法統(tǒng)計。(3)完成統(tǒng)計表及問題。(4)集體訂正。
教學(xué)內(nèi)容:教科書91頁。教學(xué)目標(biāo):1、使學(xué)生通過觀察、實驗、猜測、推理等活動發(fā)現(xiàn)數(shù)字簡單的排列規(guī)律。2、培養(yǎng)學(xué)生初步的觀察、推理能力。3、培養(yǎng)學(xué)生發(fā)現(xiàn)和欣賞數(shù)學(xué)美的意識。教學(xué)重點:通過探索自己發(fā)現(xiàn)規(guī)律教學(xué)難點:會用“規(guī)律”解決一些實際問題,并激發(fā)學(xué)生的創(chuàng)造思維。教學(xué)過程:一、揭題:小朋友們,上節(jié)課我們不僅探索了有關(guān)圖形的規(guī)律,而且還探索了有關(guān)數(shù)字的規(guī)律,這節(jié)課我們繼續(xù)來學(xué)習(xí)。二、探索新知:1、學(xué)習(xí)例7。(1)小組合作學(xué)習(xí)例7,你們能發(fā)現(xiàn)什么規(guī)律?(2)學(xué)生小組活動。(3)匯報交流:第1組都是加1,第2組都是加2,第三組也是加2。2、學(xué)習(xí)例8。(1)小組合作學(xué)習(xí)例7,你們能發(fā)現(xiàn)什么規(guī)律?(2)學(xué)生小組活動。(3)匯報交流:第1組都是加5,第2組都是加3。三、完成做一做。四、學(xué)生創(chuàng)造性地思考其他有規(guī)律的數(shù)字排列。五、總結(jié):通過這節(jié)課的學(xué)習(xí),你有什么收獲?作業(yè)布置:
六、教學(xué)反思 從這節(jié)課的實施情況看,課堂實施與原先的公開課教案是比較一致的,效果也是比較好的,主要體現(xiàn)于以下兩點: 1、效果得益于“跳出”--跳出教材框框 剛開始備課和試教時,我打算充沛利用教材,根據(jù)教材上的內(nèi)容出示幻燈片讓同學(xué)說一說,但一節(jié)課下來顯得很單調(diào)、信息量很少,體現(xiàn)不出生活中數(shù)的味道。于是我開放教材,跳出教材的框框,課前安排一個“找生活中的數(shù)”實踐活動把同學(xué)放到社會生活之林中去,讓他們先找些“野食”吃。這樣,課前在準(zhǔn)備過程當(dāng)中積累的素材多了,同學(xué)的學(xué)習(xí)效益大大提高了。同學(xué)在豐富多彩的實際生活中自由自在地采擷自身感興趣的“果子”,他們采來的“果子”是絢麗多姿的,然后回到課堂交流,共享到了“果子”的豐富,起到“以一當(dāng)數(shù)十”的作用。 這個“跳出”戰(zhàn)略,體現(xiàn)了現(xiàn)代科學(xué)“系統(tǒng)論”的理論。系統(tǒng)論認為:系統(tǒng)只有開放,不時吸收外界的信息,才干使自身“有序”。
