第四篇:數(shù)學六年級第二學期 教學輔導復習教案(滬版)
數(shù)學六年級第二學期 教學輔導復習教案(滬版)
第五章 有理數(shù)
有理數(shù)的意義;正數(shù)和負數(shù);有理數(shù)的加減;有理數(shù)的乘除;有理數(shù)的乘方.零是正數(shù)和負數(shù)的分界。
分數(shù)是由正分數(shù)和負分數(shù)組成的。
正數(shù)和分數(shù)統(tǒng)稱為有理數(shù)(rational number)
有理數(shù):正數(shù):正整數(shù)、零、負整數(shù)
分數(shù):正分數(shù)、負分數(shù)
如果我們把正數(shù)看成是分母為1的分數(shù),那么在這個意義下,所有的有理數(shù)都是分數(shù)。
數(shù)軸的定義:規(guī)定了原點、正方向和單位長度的直線叫做數(shù)軸。
任何一個有理數(shù)都可以用數(shù)軸上的一個點表示。
只有符號不同的兩個數(shù),我們稱其中一個數(shù)為另一個數(shù)的相反數(shù)(opposite number),也稱為這兩個數(shù)互為相反數(shù),零的相反數(shù)是零。
一個數(shù)在數(shù)軸上所對應的點與原點的距離,叫做這個數(shù)的絕對值(absolute value)
一個正數(shù)的絕對值是它本身。
一個附屬的絕對值是它的相反數(shù)。
零的絕對值是零。
正數(shù)大于零,零大于負數(shù),正數(shù)大于負數(shù)。
兩個負數(shù),絕對值大的那個數(shù)反而小。有理數(shù)加法法則:
同號兩數(shù)相加,取原來的符號,并把絕對值相加。
異號兩數(shù)相加,絕對值相等時和為零,絕對值不相等時,其和的絕對值為較大絕對值減去較小的絕對值所得的差,其和的符號取絕對值較大的加數(shù)的符號。
一個數(shù)同零相加,仍得這個數(shù)。
有理數(shù)加法的運算律
交換律:a+b=b+a 結合律:(a+b)+ c=a+(b+c)有理數(shù)的減法法則
減去一個數(shù),等于加上這個數(shù)的相反數(shù) a-b=a+(-b)兩數(shù)相乘的符號法則
正乘正得正,正乘負得負,負乘正得正,負乘負得正。有理數(shù)的乘法法則
兩數(shù)相乘,同號得正,異號得負,并把絕對值相乘。
任何數(shù)與零相乘,都得零。
幾個不等于零的數(shù)相乘,積的符號由負因數(shù)的個數(shù)決定,當負因數(shù)有奇數(shù)個時,積為負;當負因數(shù)有偶數(shù)個時,積為正;幾個數(shù)相乘,有因數(shù)為零,積就為零。
也就是說,在積的各個因數(shù)中,只有一個負號,積為負; 有兩個負號,積為正; 有三個負號,積為負; 有四個負號,積為正; 有零時積就是零。有理數(shù)除法法則
兩數(shù)相除,同號得正,異號得負,并把絕對值相除。
零除以任何一個不為零的數(shù),都得零。
求N個相同因數(shù)的積的運算,叫做乘方。乘法的結果叫做冪。在an中,a叫做底數(shù),n叫做指數(shù),an讀作a的n次方,an看做是a的n次方結果時,讀作a的n次冪。
正數(shù)的任何次冪都是正數(shù),負數(shù)的奇數(shù)次冪是負數(shù),負數(shù)的偶數(shù)次冪是正數(shù)。有理數(shù)混合運算的順序:先乘方,后乘除,再加減;統(tǒng)計運算從左到右;如果有括號,先算小括號,后算中括號,再算大括號。
把一個數(shù)寫成a*10n(其中1≤a<10,n是正整數(shù)),這種形式的計數(shù)方法叫做科學計數(shù)法(scientific notation)
第六章 一次方程(組)及一次不等式(組)
方程的意義;一次方程的意義;一次方程的解法;不等式的意義及解法
1、用字母x、y、等表示所要求的未知的數(shù)量,這些字母稱為未知數(shù)。含有未知數(shù)的等式叫做方程(equation)。在方程中,所含的未知數(shù)又稱為元。
為了求得未知數(shù),在未知數(shù)和已知數(shù)之間建立一種等量關系式,就是列方程。
2、如果未知數(shù)所取的某個值能使方程左右兩邊的值相等看,那么這個未知數(shù)的值叫做方程的解(solution of equation)
3、只含有一個未知數(shù)且未知數(shù)的次數(shù)是一次的方程叫做一元一次方程(linear equation in one variable)
4、等式性質1:等式兩邊同時加上(或減去)同一個數(shù)或一個含有字母的式子,說得結果仍是等式。
等式性質2:等式兩邊同時乘以同一個數(shù)(或除以同一個不為零的數(shù)),所得結果仍是等式。
5、去括號的法則是:括號前帶“+”號,去掉括號時括號內各項都不變符號。括號前帶“—”號,去掉括號時括號內各項都改變符號。
6、解一元一次方程的一般步驟是: 去括號; 化成ax=b(a≠0)的形式
設未知數(shù)(元); 解方程;
去分母; 移項;
兩邊同除以未知數(shù)的系數(shù),得到不等式的解集。
16、由幾個含有同一個未知數(shù)的一次不等式組成的不等式組,叫做一元一次不等式組。
不等式組中所有不等式的解集的公共部分叫做這個不等式組的解集。
求不等式組的解集的過程叫做解不等式組。
如果各個不等式的解集沒有公共部分,那么這個不等式組無解。
17、解一元一次不等式組的一般步驟是: 在數(shù)軸上表示各個不等式的解集;
-確定各個不等式解集的公共部分,就得到這個不等式組的解集。
18、含有兩個未知數(shù)的一次方程叫做二元一次方程。
19、使二元一次方程兩邊的值相等的兩個未知數(shù)的值,叫做二元一次方程的解。
20、二元一次方程的解有無數(shù)個,二元一次的解的全體叫做這個二元一次方程的解集。
21、由幾個方程組成的一組方程叫做方程組。如果方程組中含有兩個未知數(shù),且含未知數(shù)的項的次數(shù)都是一次,那么這樣的方程組叫做二元一次方程組。
22、在二元一次方程組中,使每個方程都適合的解,叫做二元一次方程組的解。
23、通過“代入”消去一個未知數(shù),將方程式轉化為一元一次方程,這種解
法叫做代入消元法,簡稱代入法。
24、通過將兩個方程相加(或相減)消去一個未知數(shù),將方程組轉化為一元一次方程,這種解法叫做加減消元法。
25、如果方程組中有三個未知數(shù),且含有未知數(shù)的項的次數(shù)都是一次,這樣的方程組叫做三元一次方程組。
26、列方程解應用題時要靈活選擇未知數(shù)的個數(shù)。
對于含有兩個未知數(shù)的應用題一般采用列二元一次方程組求解;對于含有三個未知數(shù)的應用題一般采用列三元一次方程組求解。
第七章 線段與角的畫法
直線的畫法;射線的畫法;線段的畫法;角的畫法;角的測量
1、聯(lián)結兩點的線段的長度叫做兩點之間的距離。
2、兩條線段可以相加(或相減),它們的和(或差)也是一條線段,其長度等于這兩條線段的長度的和(或差)。
3、將一條線段分成兩條相等線段的店叫做這條線段的中點。
4、角是具有公共端點的兩條射線組成的圖形。公共端點叫做角的頂點,兩條射線叫做角的邊。
5、角是由一條射線繞著它的端點旋轉到另一個位置所成的圖形。處于初始位置的那條射線叫做角的始邊,終止位置的那條射線叫做角的終邊。
6、兩個角可以相加(或相減),它們的和(或差)也是一個角,它的度數(shù)等于這兩個角的角度的和(或差)。
7、從一個角的頂點引出一條射線,把這個角分成兩個相等的角,這條射線叫做這個角的平分線。
8、如果兩個角的度數(shù)的和是90°,那么這兩個角叫做互為余角,簡稱互余。其中一個角成為另一個角的余角。
如果兩個角的度數(shù)的和是180°,那么這兩個角叫做互為補角,簡稱互補。其中一個角稱為另一個角的補角。
9、同角(或等角)的余角相等; 同角(或等角)的補角相等;
10、一個角與它的余角相等,這個角是怎樣的角?是銳角
一個角與它的補角相等,這個角是怎樣的角?是直角
互補的兩個角能否都是銳角?不能
能否都是直角?可能
能否都是鈍角?不能
第八章 長方體的再認識
長方體的頂點;長方體的棱;長方體的面;長方體的表面積;長方體的體積公式;
長方體有六個面,八個頂點,十二條棱。長方體的每個面都是長方形。
長方體的十二條棱可以分為三組,每組中的四條棱的長度相等。
長方體的六個面可以分為三組,每組中的兩個面的形狀和大小都相同。
第115頁:長方體中棱與棱位置關系的認識:
如圖:棱EH與棱EF所在的直線在同一個面內,它們有惟一的公共點,我們稱這兩條棱相交。
棱EF與棱AB所在的直線在同一個面內,但它們沒有公共點,我們稱這兩條棱平行。
棱EH與棱AB所在的直線既不平行,也不相交,我們稱這兩條棱異面。一般地,如果直線AB與直線CD在同一平面內,具有惟一公共點,那么稱這兩條直線的位置關系為相交,讀作:直線AB與直線CD相交。
如果直線AB與直線CD在同一平面內,但沒有公共點,那么稱這兩條直線的位置關系為平行,記作:AB∥CD,讀作:直線AB與直線CD平行。
如果直線AB與直線CD既不平行,也不相交,那么稱這兩條直線的位置關系為異面,讀作:直線AB與直線CD異面。
直線PQ垂直于平面ABCD,記?。褐本€PQ⊥平面ABCD,讀作:直線PQ垂直于平面ABCD。
如何檢驗直線與平面垂直呢?可以用“鉛垂線”檢驗。
如果細棒垂直于墻面,可以用“三角尺”檢驗。
還可以用“合頁型折紙”檢驗直線是否垂直于平面。
直線PQ平行于平面ABCD,記作:直線PQ∥平面ABCD, 讀作:直線PQ平行于平面ABCD.如何檢驗直線與平面平行呢?可以用“鉛垂線”檢驗。
也可以用“長方形紙片”檢驗。
第五篇:六年級英語復習課教案
六年級時態(tài)復習課
一、教學背景:時態(tài)是英語學習中的一個重要內容,廣大小學生在實際運用時會出現(xiàn)混淆的情況。在這八冊書中出現(xiàn)了一般現(xiàn)在時、現(xiàn)在進行時、一般過去時和一般將來時這四種時態(tài),我將會用兩節(jié)課對這四種時態(tài)進行復習。
二、教學內容:復習語法一般過去時和一般將來時。
三、教學目標:
1、復習一般過去時和一般將來時兩種時態(tài)并讓學生能夠能靈活運用。
2、通過聽說讀寫訓練,發(fā)展學生綜合運用語言的能力,培養(yǎng)學生參與課堂教學的興趣和積極性,以及培養(yǎng)他們運用語法知識的交際能力。
四、教學準備:多媒體課件
五、教學過程: Step 1: Warm-up
1、Greetings Good afternoon, boys and girls.Good afternoon, teacher
2、Daily talk(t-s)(大概)Eg:What did you /he /she do ?? What did you /he /she do …? Did you go to …
What are you going to do … What is he/ she going to do … Are you going to…
(設計意圖:由老師與學生的自由交流,自然地復習了過去時和將來時的句子,喚醒對這兩種時態(tài)的記憶,并拉近了師生之間的距離,營造英語氛圍,引導學生樂于用英語開口說話。)
3、Sing a song: What are you going to do?
(設計意圖:利用歌曲復習將來時,為下面的課堂教學做好鋪墊,活躍課堂氣氛并激發(fā)學生學習興趣。)Step2: Presentation/Practice
1、Brain storm(PPT出示動詞圖片、詞組,學生快速朗讀一次)A、過去式的復習Da Xiong’s Last Week
Da Xiong:(crying)I failed the English test.Ding Dang: I am sorry to hear that.What did you do last week? Da Xiong: Oh!I was busy last week.I went to a park by bus last Monday.I took many pictures with my friends last Tuesday.I played football last Wednesday.I walked to grandma’s home last Thursday.I watched TV last Friday…Ha,ha, I was so happy.Ding Dang: Oh!You always play.That’s why you failed the English test.(設計意圖:利用學生熟悉的動畫引入過去時,能很好地激發(fā)學生的學習興趣,并給學生提供了很好的聽力和筆試練習,使本來枯燥的練習課變得生動。)
1、回答問題:What did Da Xiong do last Friday?(He watched TV last Friday.)并板書:He watched TV last Friday.2、看圖(PPT)提問、回答并完成下題
(以人機對話的形式讓學生提問大雄,然后錄音回答,學生根據(jù)回答的內容完成下列短文。)
Da Xiong
to a park by bus last Monday.He
many pictures with his friends last Tuesday.He
football last Wednesday.He
to grandma’s home last Thursday.He
TV last Friday.He was happy.1、寫出動詞的過去式
T: Da Xiong failed the exam.Why? Is it very difficult? Let’s help him.呈現(xiàn)大雄的試題:
寫出下列動詞的過去式,并在橫線上寫出你知道的更多的動詞及過去式: clean()climb()wash()watch()dance()study()
see()take()swim()fly()
I can write more:
Check the answers.檢查誰寫的動詞過去式多(教師檢查及學生小組內檢查)小結動詞過去式的四種情況(PPT)
(設計意圖:通過做大雄的試題進行筆試練習,讓學生檢查自己的學習情況,試題能幫助學生歸類出動詞的過去式的幾種形式:
1、一般在動詞詞尾加ed。
2、如果動詞以字母e結尾,變過去式時直接在詞尾加d。
3、如果動詞是以輔音字母加y結尾,變過去式時要變y為i再加ed。
4、部分不規(guī)則動詞的過去式。而且試題設計一條橫線讓學生自己寫更多的動詞及過去式,具有靈活性。)
2、Let’s chant Is, was, are, were.Ready? Go, went, went to a park See, saw, saw elephants Eat, ate, ate good food Read, read, read a book Take, took, took pictures Swim, swam, swam in the sea What did you do last weekend? I ate, ate, ate good food.(設計意圖: 通過chant 的形式進一步鞏固過去時及短語搭配。歡快的節(jié)奏活躍課堂氣氛、調整孩子們疲勞的腦神經(jīng),也為知識的鞏固降低了難度。)B、將來時的復習
T:If you are Da Xiong, what are you going to do next week? S1:I am going to…
S2:I am going to…
T:OK, let’s see what is Da Xiong going to do next week? Da Xiong’s Next Week
Ding Dang: Da Xiong, there is another test 1 week later.What are you going to do next week? Da Xiong: What shall I do? Oh, I see.I will study hard next week.I’m going to read English with my sister next Monday.I’m going to read a book next Tuesday.I’m
going to do my homework next Wednesday.I’m going to Mike’s home by bike next Thursday afternoon.I’m going to watch TV Friday evening… Ding Dang: That’s right.1、1st listen: answer the question: What is Da Xiong going to do next week?并板書:(He is going to study hard next week.)am/is/are going to = will
3、聽音,判斷對錯并改正。
1、Da Xiong will read Chinese next Monday.()
2、He is going to watch TV next Tuesday.()
3、He is going to Mike’s home last Thursday.()
4、He is going to watching TV next Friday evening.()(設計意圖:判斷對錯的練習再次檢查了學生對叮當和大雄之間的對話的理解程度,更重要的是練習里面滲透了動詞時態(tài)與時間狀語的搭配一致性問題。)
3、擂臺賽:
T:Read the dialogue and try to ask some questions.在規(guī)定的時間內閱讀對話“Da Xiong’s Next Week”,并準備好自己的問題,然后學生分兩組進行問答擂臺賽。
(設計意圖:通過擂臺賽幫助學生復習更多將來時的句型。而且讓學生來提問,能充分調動學生的主動性,推動學生克服困難主動學習。學生們有強烈的參與意識,學生們提出充滿個性不同的問題,然后再讓學生來回答這些問題,這符合素質教育所期盼的結果,這樣比自問自答更能夠拓展學生的發(fā)散思維。而且通過競賽還可以培養(yǎng)學生個人自信心和集體榮譽感。)C、過去式與將來時的綜合練習
1、Changing partners(練習下列句型)A、用過去式造陳述句 I ate good food.B、用將來時造陳述句 I am going to?
C、用Where , What, How? 造過去式或將來時的問句
(設計意圖:分三步進行“變換伙伴”的活動,讓學生在較短的時間內造出過去式、將來時的句子及兩種時態(tài)的混合問答,進一步加強了學生對兩種時態(tài)的表達練習。)
2、Make a postcard to Da Xiong.T: Design your postcard in your group, and then write sth about your “l(fā)ast weekend” and “next weekend”.(設計意圖:通過讓學生通過小組合作的形式,給大雄設計一份post card,寫出自己上周和下周的活動,從而在筆頭上綜合檢查學生對過去式和將來時的掌握情況,而且在這個活動中培養(yǎng)學生的合作精神。)Step4 : Summary
1、引導學生總結本課的重點(兩種時態(tài)及句子的主要結構)。
2、根據(jù)本課主線人物大雄引導學生教育學生珍惜時間,努力學習,進行情感教育。
Step 5: Homework Make a book : My Weekends(含過去與將來)教師先展示自己的書(Say goodbye to Da Xiong and Di Dang)
六、板書設計

1這節(jié)課,我們復習的是一般現(xiàn)在時的用法,一起來看一看一般現(xiàn)在時的“自我介紹”!Hello!大家好,我叫“一般現(xiàn)在時”,你想知道我的故事嗎?
Let me tell you!首先,看看我的本領吧。我被大家用來表示經(jīng)常性的動作或存在的狀態(tài)。
下面請看我的面目—我的構成: 我常常與often, usually, Sometimes ,on Sundays等詞連用,動詞用原形。不過當主語是第三人稱單數(shù)時,要在動詞后加s或es。例:
I often read books at home.She plays the violin every day.如果是疑問句,還要用助動詞do(主語是第三人稱單數(shù)用does)構成,動詞用原形。例:
Do you usually play football after school ? What does he do on Sundays? 下次見到我時,千萬不要忘記我是“一般現(xiàn)在時”?。ee you!2我們知道一般現(xiàn)在時,主語是第三人稱單數(shù)時動詞會有變化。我們一起來總結一下,有哪些變化呢?
順口溜:肯定句中,他、她、它,動詞后面加尾巴。一般動詞直接加s,有些加es 以輔音字母加結尾的,變y為i加es 3 讀一讀變化后的動詞。Step 6 Let’s do some exercise.Finish the exercise with proper words.a.Sometimes, I ________ basketball after school.My father usually ________ newspapers in the evening.________ your mother _________ shopping every Friday afternoon? What ________ Helen usually ________ on Saturdays? e.I like Chinese, but my friend, Ben _________ PE.2 Listening exercise.T: I wrote an e-mail to you.Please help me finish it.S: Listen and fill in the blanks.Step 7 Homework 向我介紹你的好朋友們。
