4.有8種不同的菜種,任選4種種在不同土質(zhì)的4塊地里,有 種不同的種法. 解析:將4塊不同土質(zhì)的地看作4個不同的位置,從8種不同的菜種中任選4種種在4塊不同土質(zhì)的地里,則本題即為從8個不同元素中任選4個元素的排列問題,所以不同的種法共有A_8^4 =8×7×6×5=1 680(種).答案:1 6805.用1、2、3、4、5、6、7這7個數(shù)字組成沒有重復(fù)數(shù)字的四位數(shù).(1)這些四位數(shù)中偶數(shù)有多少個?能被5整除的有多少個?(2)這些四位數(shù)中大于6 500的有多少個?解:(1)偶數(shù)的個位數(shù)只能是2、4、6,有A_3^1種排法,其他位上有A_6^3種排法,由分步乘法計數(shù)原理,知共有四位偶數(shù)A_3^1·A_6^3=360(個);能被5整除的數(shù)個位必須是5,故有A_6^3=120(個).(2)最高位上是7時大于6 500,有A_6^3種,最高位上是6時,百位上只能是7或5,故有2×A_5^2種.由分類加法計數(shù)原理知,這些四位數(shù)中大于6 500的共有A_6^3+2×A_5^2=160(個).

(2)方法一:第一次取到一件不合格品,還剩下99件產(chǎn)品,其中有4件不合格品,95件合格品,于是第二次又取到不合格品的概率為4/99,由于這是一個條件概率,所以P(B|A)=4/99.方法二:根據(jù)條件概率的定義,先求出事件A,B同時發(fā)生的概率P(AB)=(C_5^2)/(C_100^2 )=1/495,所以P(B|A)=(P"(" AB")" )/(P"(" A")" )=(1/495)/(5/100)=4/99.6.在某次考試中,要從20道題中隨機地抽出6道題,若考生至少答對其中的4道題即可通過;若至少答對其中5道題就獲得優(yōu)秀.已知某考生能答對其中10道題,并且知道他在這次考試中已經(jīng)通過,求他獲得優(yōu)秀成績的概率.解:設(shè)事件A為“該考生6道題全答對”,事件B為“該考生答對了其中5道題而另一道答錯”,事件C為“該考生答對了其中4道題而另2道題答錯”,事件D為“該考生在這次考試中通過”,事件E為“該考生在這次考試中獲得優(yōu)秀”,則A,B,C兩兩互斥,且D=A∪B∪C,E=A∪B,由古典概型的概率公式及加法公式可知P(D)=P(A∪B∪C)=P(A)+P(B)+P(C)=(C_10^6)/(C_20^6 )+(C_10^5 C_10^1)/(C_20^6 )+(C_10^4 C_10^2)/(C_20^6 )=(12" " 180)/(C_20^6 ),P(E|D)=P(A∪B|D)=P(A|D)+P(B|D)=(P"(" A")" )/(P"(" D")" )+(P"(" B")" )/(P"(" D")" )=(210/(C_20^6 ))/((12" " 180)/(C_20^6 ))+((2" " 520)/(C_20^6 ))/((12" " 180)/(C_20^6 ))=13/58,即所求概率為13/58.

二、說教法、學(xué)法：根據(jù)本節(jié)課的教學(xué)目標。重點、難點設(shè)置，我確定本節(jié)課的教法與學(xué)法： 我國教育家葉圣陶先生曾經(jīng)說過“教師教任何功課，‘講’都是為了達到用不著‘講’，‘教’都是為了達到用不著‘教’”，這一精辟結(jié)論強調(diào)了教師要教會學(xué)生如何學(xué)習(xí)，讓學(xué)生一輩子受用。為突出重點，分散難點，始終使學(xué)生參與知識形成的過程。引導(dǎo)學(xué)生將“圖”與“式”對照起來，進行分析和說理。從而在發(fā)揮直觀形象思維對于抽象邏輯思維支持作用的同時，讓學(xué)生逐漸感受數(shù)形結(jié)合的優(yōu)勢。根據(jù)高年級學(xué)生已具有處理信息和自主學(xué)習(xí)的能力，我設(shè)計了4個教學(xué)環(huán)節(jié)。教學(xué)中通過學(xué)生觀察、分析、討論、合作等方式，引導(dǎo)學(xué)生尋找計算方法，并通過發(fā)現(xiàn)、總結(jié)、運用法則調(diào)動學(xué)生的積極性。

三、總結(jié)規(guī)律、形成概念通過學(xué)生積極討論，充分調(diào)動了學(xué)生的積極參與學(xué)習(xí)，既發(fā)揮了學(xué)生學(xué)習(xí)的主動性，又培養(yǎng)了學(xué)生的發(fā)散性思維，引導(dǎo)學(xué)生總結(jié)出：有的分數(shù)可以化成有限小數(shù)，有的分數(shù)不可以化成有限小數(shù)，請同學(xué)們再看一看什么樣的分數(shù)可以化成有限小數(shù)？什么樣的分數(shù)不可以化成有限小數(shù)？啟發(fā)學(xué)生從分母的最小公倍數(shù)著手。 最后總結(jié)出：一個最簡分數(shù)，如果分母中只含有素因數(shù)2和5，再無其它素因數(shù)，那么這個分數(shù)就可以化成有限小數(shù)，否則就不能化成有限小數(shù)。 例題2，請把下列小數(shù)化成分數(shù)，說說你是怎樣把小數(shù)化成分數(shù)的？ 0.06，0.4，1.8，2.45，1.465, 歸納：（學(xué)生為主，教師點撥）1、原來有幾位小數(shù)，就在1后面寫幾個零作分母。原來的小數(shù)去掉小數(shù)點作分子。2、小數(shù)化成分數(shù)后，能約分的要約分。常用的因數(shù)是2和5。 對于小數(shù)如何化成分數(shù)的題目，課前了解到學(xué)生在小學(xué)時已學(xué)過把小數(shù)如何化成分數(shù)的方法，因而以學(xué)生練習(xí)為主，加以操練并鞏固，有錯誤的及時糾正。

三、鞏固練習(xí)，拓展應(yīng)用練習(xí)是學(xué)生領(lǐng)悟知識，形成技能，發(fā)展智力的重要手段，我遵循“由淺入深，循序漸進”的原則設(shè)計了以下不同層次的練習(xí)。1、基本練習(xí)自主練習(xí)第1題填一填，借助直觀圖，鞏固分數(shù)乘法的意義和計算方法。2、提高練習(xí)自主練習(xí)2、4題。本題的設(shè)計，目的是使學(xué)生除了掌握基本的數(shù)學(xué)知識和技能外，初步學(xué)會從數(shù)學(xué)的角度去觀察事物、思考問題，同時，也讓學(xué)生感受到生活中處處有數(shù)學(xué)，從而激發(fā)對數(shù)學(xué)的興趣，以及學(xué)好數(shù)學(xué)的愿望。四、課堂小結(jié)，升華認識引導(dǎo)學(xué)生回憶總結(jié)：這節(jié)課你們都知道了些什么？你有哪些收獲？這節(jié)課你表現(xiàn)得怎樣？等等，這樣的小結(jié)有利于學(xué)生鞏固本節(jié)課的重點，獲得成功的體驗，激發(fā)學(xué)習(xí)的熱情。五、板書設(shè)計：簡單明了，能系統(tǒng)地反映出本課的重、難點。有利于學(xué)生形成一定的知識網(wǎng)絡(luò)。都起到了“畫龍點睛”的作用。

二、教法運用分數(shù)在日常生活中經(jīng)常出現(xiàn)，但學(xué)生對它的認識卻各不相同。新課程標準視學(xué)習(xí)為“做”的過程、“經(jīng)驗”的過程，凸現(xiàn)學(xué)生學(xué)習(xí)的實踐性特點。因此，本課的設(shè)計力求在教法上體現(xiàn)“在玩中學(xué)，在做中學(xué)，在合作交流中學(xué)”的思想。本節(jié)課以引導(dǎo)發(fā)現(xiàn)法為主，綜合運用多種教法，創(chuàng)設(shè)有利于學(xué)生參與探索活動的學(xué)習(xí)環(huán)境，幫助學(xué)生學(xué)習(xí)分數(shù)的有關(guān)知識，實現(xiàn)促進學(xué)生能力發(fā)展的教育目標。三、學(xué)法指導(dǎo)在學(xué)法上則突出“自主學(xué)習(xí)，實踐感知”的特點，加強數(shù)學(xué)實踐活動，讓學(xué)生主動建構(gòu)數(shù)學(xué)知識。學(xué)生對數(shù)學(xué)知識的學(xué)習(xí)，不是被動接受，而是主動建構(gòu)，而動手操作對學(xué)生的建構(gòu)有著積極的促進作用。讓學(xué)生在動手、動腦、動口的過程中實現(xiàn)知識的遷移類推，主動建構(gòu)數(shù)學(xué)知識。

教材分析這部分內(nèi)容是在認識鐘表上的整時、半時的基礎(chǔ)上進一步認識鐘面上的時、分。分是非常重要的時間單位，也是進一步學(xué)習(xí)年、月、日的基礎(chǔ)。時間單位不像長度、質(zhì)量單位那樣容易表現(xiàn)出來，比較抽象，學(xué)生不容易理解。所以，應(yīng)以學(xué)生的生活經(jīng)驗為基礎(chǔ)，把學(xué)習(xí)內(nèi)容與學(xué)生的生活實際密切聯(lián)系起來，進行教學(xué)?！拔覀冓A了”是結(jié)合“北京申奧成功”這一情境，讓我們記住這一歷史時刻——2001年7月13日晚上10時08分。用記載著這一歷史時刻的鐘面，引導(dǎo)學(xué)生交流自己對鐘面的認識，激活學(xué)生已有的生活經(jīng)驗；同時，抓住機會滲透愛國主義教育，引導(dǎo)學(xué)生關(guān)注社會，關(guān)心時事。學(xué)情分析學(xué)生在一年級時已經(jīng)學(xué)過了鐘面的簡單知識并會認識整時和整時半。但有關(guān)時間的認知顯得有些混亂，對時針和分針表示的意義分辨不清，多數(shù)孩子還不能讀出準確的時刻。

五、鞏固運用 深化理解1、教材28頁上的第一道練習(xí)題，請個別學(xué)生到視頻展臺做此題，2、游戲鞏固老師左手拿一個三角形，右手拿一張卡紙遮住三角形的兩個角，只露出一個角，讓學(xué)生猜這會是什么樣的三角形？ 設(shè)計第一道練習(xí)題目的在于鞏固新知，形成技能，培養(yǎng)學(xué)生聯(lián)系新知識，靈活解決問題的能力。當學(xué)生感到有些疲勞時，這時我就根據(jù)教材內(nèi)容和學(xué)生心理特點，采用學(xué)生喜聞樂見的游戲練習(xí)方式，增加題目的趣味性，激發(fā)學(xué)生的學(xué)習(xí)興趣。六、總結(jié)評價，體驗成功讓學(xué)生談?wù)劷?jīng)過自己動手操作、小組合作、自主探索發(fā)現(xiàn)的三角形分類方法及各種三角形特征，不僅及時有效地鞏固所學(xué)知識，訓(xùn)練學(xué)生的語言表達能力，而且可以使學(xué)生從中感受、體驗到一個探索者的成功樂趣，從而增強學(xué)習(xí)動力與信心。
小學(xué)數(shù)學(xué)人教版六年級上冊《百分數(shù)整理與復(fù)習(xí)》說課稿
一、說教材《百分數(shù)》是九年義務(wù)教育課程標準試驗教科書人教版小學(xué)數(shù)學(xué)五年級下冊第六單元的教學(xué)內(nèi)容。百分數(shù)是在學(xué)過整數(shù)、小數(shù)，特別是分數(shù)的意義和應(yīng)用的基礎(chǔ)上進行教學(xué)的。本單元教材在編寫上體現(xiàn)從實際情境中抽象出百分數(shù)的過程。讓學(xué)生體會引入百分數(shù)的必要性和百分數(shù)的意義，感受百分數(shù)在實際生活中的應(yīng)用。二、說學(xué)情學(xué)生已經(jīng)認識了百分數(shù)，并掌握了百分數(shù)的簡單計算和應(yīng)用。生活中存在著較多的百分數(shù)，學(xué)生在生活中或有所見、或有所聞。如衣服上 80％棉、牛奶純度 100％等等。這些為本節(jié)課的開展奠定了生活經(jīng)驗基礎(chǔ)。
