（1） 你是用什么方法解方程的？要求學(xué)生獨(dú)立完成。請(qǐng)一位同學(xué)在黑板上計(jì)算。學(xué)生交流：等式的兩邊同時(shí)加上同一個(gè)數(shù)，等式仍然成立。也就是方程 x-9=15的兩邊同時(shí)加上9，抵消掉等式左邊的9，這樣等式的左邊只剩下x。（2） 你會(huì)檢驗(yàn)方程的解是否正確嗎？指導(dǎo)學(xué)生把方程的解代入方程進(jìn)行檢驗(yàn)。2.出示：64頁第2題的第2小題。提問：你是根據(jù)哪個(gè)等量關(guān)系列出方程的？（1） 標(biāo)準(zhǔn)體重+超出標(biāo)準(zhǔn)的重量=胖胖的體重（2） 標(biāo)準(zhǔn)體重-低于標(biāo)準(zhǔn)的重量=小明的體重提問：他們標(biāo)準(zhǔn)體重的計(jì)算方法有什么不同？學(xué)生交流：一個(gè)是等式兩邊同時(shí)減去同一個(gè)數(shù)，一個(gè)是等式兩邊同時(shí)加上同一個(gè)數(shù)。三、拓寬應(yīng)用。1.解方程：x-5.3=10 75-x=402.65頁第4題提問：你是怎樣選出各方程的解的？把未知數(shù)的值代入方程，看看左右是否相等。3.65頁第5題提示學(xué)生認(rèn)真讀題，注意選擇題中所給出的條件是否有用。

二、探究交流，引導(dǎo)概括 —— 方程為了培養(yǎng)學(xué)生的發(fā)現(xiàn)和抽象概括能力，同時(shí)進(jìn)一步理解方程的意義，我讓學(xué)生分組學(xué)習(xí)，引導(dǎo)他們先找出②20+χ=100，⑥ 3χ=180，⑧100+2χ=3×50像上面三臄?shù)仁降挠泄餐卣?，然后歸納概括什么叫做方程？最后得出：像這樣的含有未知數(shù)的等式，叫做方程。三、討論比較，辨析、概念 —— 等式與方程的關(guān)系為了體現(xiàn)學(xué)生的主體性，培養(yǎng)學(xué)生的合作意識(shí)，同時(shí)讓學(xué)生在解決問題的過程中得到創(chuàng)造的樂趣。通過四人合作用自己的方法創(chuàng)作 “ 方程 ” 與 “ 等式 ” 的關(guān)系圖，并用自己的話說一說 “ 等式 ” 與 “ 方程 ” 的關(guān)系：方程一定是等式，但等式不一定是方程。四、鞏固深化，拓展思維 —— 練習(xí)1 、“做一做”：2、判斷是否方程3、“方程一定是等式，等式也一定是方程”這句話對(duì)嗎？4、叫學(xué)生用圖來表示等式和方程的關(guān)系。

（六）說教學(xué)策略1.專題性海量的媒介信息必須加以選擇或者整合，以項(xiàng)目為依據(jù)，進(jìn)行信息篩選，形成專題性閱讀與交流；培養(yǎng)學(xué)生對(duì)文本信息“化零為整”的能力，提升跨媒介閱讀與交流學(xué)習(xí)的充實(shí)感。2.情境化情境教學(xué)應(yīng)指向?qū)W生的應(yīng)用，建構(gòu)富有符合時(shí)代氣息的內(nèi)容，與生活經(jīng)驗(yàn)更加貼合，對(duì)學(xué)生的語言建構(gòu)與運(yùn)用有所提升，在情境中能夠有效地進(jìn)行交流。3.任務(wù)化以任務(wù)為導(dǎo)向的序列化學(xué)習(xí)，可以為學(xué)生構(gòu)建學(xué)習(xí)路線圖、學(xué)習(xí)框架等具體任務(wù)引導(dǎo)；或以跨媒介的認(rèn)識(shí)與應(yīng)用為任務(wù)的設(shè)置引導(dǎo)；甚至以閱讀和交流作為序列化安排的實(shí)踐引導(dǎo)。4.整合性跨媒介閱讀與交流是結(jié)合線上線下的資源，形成新的“超媒介”，也能實(shí)現(xiàn)對(duì)信息進(jìn)行“深加工”，多種媒介的信息整合只為一個(gè)核心教學(xué)內(nèi)容服務(wù)。5.互文性語言文字是語文之生命，我們是立足于語言文字的探討，音樂、圖像、視頻等文本與傳統(tǒng)語言文字文本形成互文，觸發(fā)學(xué)生對(duì)學(xué)習(xí)內(nèi)容立體化和具體化的感悟，提升學(xué)生的審美能力。

解：(1)設(shè)第一次購買的單價(jià)為x元，則第二次的單價(jià)為1.1x元，根據(jù)題意得14521.1x－1200x＝20，解得x＝6.經(jīng)檢驗(yàn)，x＝6是原方程的解．(2)第一次購買水果1200÷6＝200(千克)．第二次購買水果200＋20＝220(千克)．第一次賺錢為200×(8－6)＝400(元)，第二次賺錢為100×(9－6.6)＋120×(9×0.5－6.6)＝－12(元)．所以兩次共賺錢400－12＝388(元)．答：第一次水果的進(jìn)價(jià)為每千克6元；該老板兩次賣水果總體上是賺錢了，共賺了388元．方法總結(jié)：本題具有一定的綜合性，應(yīng)該把問題分解成購買水果和賣水果兩部分分別考慮，掌握這次活動(dòng)的流程．三、板書設(shè)計(jì)列分式方程解應(yīng)用題的一般步驟是：第一步，審清題意；第二步，根據(jù)題意設(shè)未知數(shù)；第三步，根據(jù)題目中的數(shù)量關(guān)系列出式子，并找準(zhǔn)等量關(guān)系，列出方程；第四步，解方程，并驗(yàn)根，還要看方程的解是否符合題意；最后作答．

【類型三】 分式方程無解，求字母的值若關(guān)于x的分式方程2x－2＋mxx2－4＝3x＋2無解，求m的值．解析：先把分式方程化為整式方程，再分兩種情況討論求解：一元一次方程無解與分式方程有增根．解：方程兩邊都乘以(x＋2)(x－2)，得2(x＋2)＋mx＝3(x－2)，即(m－1)x＝－10.①當(dāng)m－1＝0時(shí)，此方程無解，此時(shí)m＝1；②方程有增根，則x＝2或x＝－2，當(dāng)x＝2時(shí)，代入(m－1)x＝－10得(m－1)×2＝－10，m＝－4；當(dāng)x＝－2時(shí)，代入(m－1)x＝－10得(m－1)×(－2)＝－10，解得m＝6，∴m的值是1，－4或6.方法總結(jié)：分式方程無解與分式方程有增根所表達(dá)的意義是不一樣的．分式方程有增根僅僅針對(duì)使最簡公分母為0的數(shù)，分式方程無解不但包括使最簡公分母為0的數(shù)，而且還包括分式方程化為整式方程后，使整式方程無解的數(shù)．三、板書設(shè)計(jì)1．分式方程的解法方程兩邊同乘以最簡公分母，化為整式方程求解，再檢驗(yàn)．2．分式方程的增根(1)解分式方程為什么會(huì)產(chǎn)生增根；(2)分式方程檢驗(yàn)的方法．
