一、情境導(dǎo)入1．計(jì)算：(1)－6x3y4z2÷(－23x2y2)；(2)9mn÷(－6mn)2·(13n2)；(3)6(a－b)3c5÷[－35(a－b)2c]·[－2(a－b)3c4]．2．m(a＋b＋c)＝am＋bm＋cm，(am＋bm＋cm)÷m＝am÷m＋bm÷m＋cm÷m＝a＋b＋c.你能根據(jù)多項(xiàng)式乘以單項(xiàng)式的運(yùn)算歸納出多項(xiàng)式除以單項(xiàng)式的運(yùn)算法則嗎？二、合作探究探究點(diǎn)：多項(xiàng)式除以單項(xiàng)式【類型一】 直接利用多項(xiàng)式除以單項(xiàng)式進(jìn)行計(jì)算計(jì)算：(72x3y4－36x2y3＋9xy2)÷(－9xy2)．解析：根據(jù)多項(xiàng)式除以單項(xiàng)式，先用多項(xiàng)式的每一項(xiàng)分別除以這個(gè)單項(xiàng)式，然后再把所得的商相加．解：原式＝72x3y4÷(－9xy2)＋(－36x2y3)÷(－9xy2)＋9xy2÷(－9xy2)＝－8x2y2＋4xy－1.方法總結(jié)：多項(xiàng)式除以單項(xiàng)式，先把多項(xiàng)式的每一項(xiàng)都分別除以這個(gè)單項(xiàng)式，然后再把所得的商相加．
北師大初中七年級(jí)數(shù)學(xué)下冊(cè)利用“邊邊邊”判定三角形全等教案
解析：由于多邊形(三邊以上的)不具有穩(wěn)定性，將其轉(zhuǎn)化為三角形后木架的形狀就不變了．根據(jù)具體多邊形轉(zhuǎn)化為三角形的經(jīng)驗(yàn)及題中所加木條可找到一般規(guī)律．解：過(guò)n邊形的一個(gè)頂點(diǎn)可以作(n－3)條對(duì)角線，把多邊形分成(n－2)個(gè)三角形，所以，要使一個(gè)n邊形木架不變形，至少需要(n－3)根木條固定．方法總結(jié)：將多邊形轉(zhuǎn)化為三角形時(shí)，所需要的木條根數(shù)，可從具體到一般去發(fā)現(xiàn)規(guī)律，然后驗(yàn)證求解．三、板書(shū)設(shè)計(jì)1．邊邊邊：三邊對(duì)應(yīng)相等的兩個(gè)三角形全等，簡(jiǎn)寫(xiě)成“邊邊邊”或“SSS”．2．三角形的穩(wěn)定性本節(jié)課從操作探究活動(dòng)入手，有效地激發(fā)了學(xué)生的學(xué)習(xí)積極性和探究熱情，提高了課堂的教學(xué)效率，促進(jìn)了學(xué)生對(duì)新知識(shí)的理解和掌握．從課堂教學(xué)的情況來(lái)看，學(xué)生對(duì)“邊邊邊”掌握較好，達(dá)到了教學(xué)的預(yù)期目的．存在的問(wèn)題是少數(shù)學(xué)生在輔助線的構(gòu)造上感到困難，不知道如何添加合理的輔助線，還需要在今后的教學(xué)中進(jìn)一步加強(qiáng)鞏固和訓(xùn)練
北師大初中七年級(jí)數(shù)學(xué)下冊(cè)利用“角邊角”“角角邊”判定三角形全等教案
1．理解并掌握三角形全等的判定方法——“角邊角”“角角邊”；(重點(diǎn))2．能運(yùn)用“角邊角”“角角邊”判定方法解決有關(guān)問(wèn)題．(難點(diǎn)) 一、情境導(dǎo)入如圖所示，某同學(xué)把一塊三角形的玻璃不小心打碎成了三塊，現(xiàn)在要到玻璃店去配一塊完全一樣的玻璃，那么最省事的辦法是帶哪塊去？學(xué)生活動(dòng)：學(xué)生先自主探究出答案，然后再與同學(xué)進(jìn)行交流．教師點(diǎn)撥：顯然僅僅帶①或②是無(wú)法配成完全一樣的玻璃的，而僅僅帶③則可以，為什么呢？本節(jié)課我們繼續(xù)研究三角形全等的判定方法．二、合作探究探究點(diǎn)一：全等三角形判定定理“ASA”如圖，AD∥BC，BE∥DF，AE＝CF，試說(shuō)明：△ADF≌△CBE.解析：根據(jù)平行線的性質(zhì)可得∠A＝∠C，∠DFE＝∠BEC，再根據(jù)等式的性質(zhì)可得AF＝CE，然后利用“ASA”可得到△ADF≌△CBE.
北師大初中七年級(jí)數(shù)學(xué)下冊(cè)三角形的三邊關(guān)系教案
方法總結(jié)：絕對(duì)值的化簡(jiǎn)首先要判斷絕對(duì)值符號(hào)里面的式子的正負(fù)，然后根據(jù)絕對(duì)值的性質(zhì)將絕對(duì)值的符號(hào)去掉，最后進(jìn)行化簡(jiǎn)．此類問(wèn)題就是根據(jù)三角形的三邊關(guān)系，判斷絕對(duì)值符號(hào)里面式子的正負(fù)，然后進(jìn)行化簡(jiǎn)．三、板書(shū)設(shè)計(jì)1．三角形按邊分類：有兩邊相等的三角形叫做等腰三角形，三邊都相等的三角形是等邊三角形，三邊互不相等的三角形是不等邊三角形．2．三角形中三邊之間的關(guān)系：三角形任意兩邊之和大于第三邊，三角形任意兩邊之差小于第三邊．本節(jié)課讓學(xué)生經(jīng)歷一個(gè)探究解決問(wèn)題的過(guò)程，抓住“任意的三條線段能不能圍成一個(gè)三角形”引發(fā)學(xué)生探究的欲望，圍繞這個(gè)問(wèn)題讓學(xué)生自己動(dòng)手操作，發(fā)現(xiàn)有的能圍成，有的不能圍成，由學(xué)生自己找出原因，為什么能？為什么不能？初步感知三條邊之間的關(guān)系，重點(diǎn)研究“能圍成三角形的三條邊之間到底有什么關(guān)系”．通過(guò)觀察、驗(yàn)證、再操作，最終發(fā)現(xiàn)三角形任意兩邊之和大于第三邊這一結(jié)論．這樣教學(xué)符合學(xué)生的認(rèn)知特點(diǎn)，既增加了學(xué)習(xí)興趣，又增強(qiáng)了學(xué)生的動(dòng)手能力
北師大初中七年級(jí)數(shù)學(xué)下冊(cè)用表格表示的變量間關(guān)系教案
解：(1)電動(dòng)車的月產(chǎn)量y為隨著時(shí)間x的變化而變化，有一個(gè)時(shí)間x就有唯一一個(gè)y與之對(duì)應(yīng)，月產(chǎn)量y是時(shí)間x的因變量；(2)6月份產(chǎn)量最高，1月份產(chǎn)量最低；(3)6月份和1月份相差最大，在1月份加緊生產(chǎn)，實(shí)現(xiàn)產(chǎn)量的增值．方法總結(jié)：觀察因變量隨自變量變化而變化的趨勢(shì)，實(shí)質(zhì)是觀察自變量增大時(shí)，因變量是隨之增大還是減?。?、板書(shū)設(shè)計(jì)1．常量與變量：在一個(gè)變化過(guò)程中，數(shù)值發(fā)生變化的量為變量，數(shù)值始終不變的量稱之為常量．2．用表格表示數(shù)量間的關(guān)系：借助表格表示因變量隨自變量的變化而變化的情況．自變量和因變量是用來(lái)描述我們所熟悉的變化的事物以及自然界中出現(xiàn)的一些變化現(xiàn)象的兩個(gè)重要的量，對(duì)于我們所熟悉的變化，在用了這兩個(gè)量的描述之后更加鮮明．本節(jié)是學(xué)好本章的基礎(chǔ)，教學(xué)中立足于學(xué)生的認(rèn)知基礎(chǔ)，激發(fā)學(xué)生的認(rèn)知沖突，提升學(xué)生的認(rèn)知水平，使學(xué)生在原有的知識(shí)基礎(chǔ)上迅速遷移到新知上來(lái)
北師大初中七年級(jí)數(shù)學(xué)下冊(cè)用科學(xué)記數(shù)法表示較小的數(shù)教案
方法總結(jié)：絕對(duì)值小于1的數(shù)也可以用科學(xué)記數(shù)法表示，一般形式為a×10－n，其中1≤a<10，n為正整數(shù)．與較大數(shù)的科學(xué)記數(shù)法不同的是其所使用的是負(fù)整數(shù)指數(shù)冪，指數(shù)由原數(shù)左邊起第一個(gè)不為零的數(shù)前面的0的個(gè)數(shù)所決定．【類型二】 將用科學(xué)記數(shù)法表示的數(shù)還原為原數(shù)用小數(shù)表示下列各數(shù)：(1)2×10－7; (2)3.14×10－5；(3)7.08×10－3; (4)2.17×10－1.解析：小數(shù)點(diǎn)向左移動(dòng)相應(yīng)的位數(shù)即可．解：(1)2×10－7＝0.0000002；(2)3.14×10－5＝0.0000314；(3)7.08×10－3＝0.00708； (4)2.17×10－1＝0.217.方法總結(jié)：將科學(xué)記數(shù)法表示的數(shù)a×10－n還原成通常表示的數(shù)，就是把a(bǔ)的小數(shù)點(diǎn)向左移動(dòng)n位所得到的數(shù)．三、板書(shū)設(shè)計(jì)用科學(xué)記數(shù)法表示絕對(duì)值小于1的數(shù)：一般地，一個(gè)小于1的正數(shù)可以表示為a×10n，其中1≤a<10，n是負(fù)整數(shù)．從本節(jié)課的教學(xué)過(guò)程來(lái)看，結(jié)合了多種教學(xué)方法，既有教師主導(dǎo)課堂的例題講解，又有學(xué)生主導(dǎo)課堂的自主探究．課堂上學(xué)習(xí)氣氛活躍，學(xué)生的學(xué)習(xí)積極性被充分調(diào)動(dòng)，在拓展學(xué)生學(xué)習(xí)空間的同時(shí)，又有效地保證了課堂學(xué)習(xí)質(zhì)量

"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?
