北師大初中七年級數(shù)學(xué)下冊用科學(xué)記數(shù)法表示較小的數(shù)教案
方法總結(jié)：絕對值小于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)左邊起第一個不為零的數(shù)前面的0的個數(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)點向左移動相應(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)點向左移動n位所得到的數(shù)．三、板書設(shè)計用科學(xué)記數(shù)法表示絕對值小于1的數(shù)：一般地，一個小于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)過程來看，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，在拓展學(xué)生學(xué)習(xí)空間的同時，又有效地保證了課堂學(xué)習(xí)質(zhì)量

問題：2015年9月24日，美國國家航空航天局(下簡稱：NASA)對外宣稱將有重大發(fā)現(xiàn)宣布，可能發(fā)現(xiàn)除地球外適合人類居住的星球，一時間引起了人們的廣泛關(guān)注．早在2014年，NASA就發(fā)現(xiàn)一顆行星，這顆行星是第一顆在太陽系外恒星旁發(fā)現(xiàn)的適居帶內(nèi)、半徑與地球相若的系外行星，這顆行星環(huán)繞紅矮星開普勒186，距離地球492光年.1光年是光經(jīng)過一年所行的距離，光的速度大約是3×105km/s.問：這顆行星距離地球多遠(yuǎn)(1年＝3.1536×107s)?3×105×3.1536×107×492＝3×3.1536×4.92×105×107×102＝4.6547136×10×105×107×102.問題：“10×105×107×102”等于多少呢？二、合作探究探究點：同底數(shù)冪的乘法【類型一】 底數(shù)為單項式的同底數(shù)冪的乘法計算：(1)23×24×2；(2)－a3·(－a)2·(－a)3；(3)mn＋1·mn·m2·m.解析：(1)根據(jù)同底數(shù)冪的乘法法則進(jìn)行計算即可；(2)先算乘方，再根據(jù)同底數(shù)冪的乘法法則進(jìn)行計算即可；(3)根據(jù)同底數(shù)冪的乘法法則進(jìn)行計算即可．
北師大初中八年級數(shù)學(xué)下冊一元一次不等式組的解法教案
把解集在數(shù)軸上表示出來，并將解集中的整數(shù)解寫出來．解析：分別計算出兩個不等式的解集，再根據(jù)大小小大中間找確定不等式組的解集，再找出解集范圍內(nèi)的整數(shù)即可．解：x＋23<1?、?，2（1－x）≤5?、?，由①得x＜1，由②得x≥－32，∴不等式組的解集為－32≤x＜1.則不等式組的整數(shù)解為－1，0.方法總結(jié)：此題主要考查了一元一次不等式組的解法，解決此類問題的關(guān)鍵在于正確解得不等式組或不等式的解集，然后再根據(jù)題目中對于解集的限制得到下一步所需要的條件，再根據(jù)得到的條件進(jìn)而求得不等式組的整數(shù)解．三、板書設(shè)計一元一次不等式組概念解法不等式組的解集利用數(shù)軸確定解集利用口訣確定解集解一元一次不等式組是建立在解一元一次不等式的基礎(chǔ)之上．解不等式組時，先解每一個不等式，再確定各個不等式組的解集的公共部分.
北師大初中八年級數(shù)學(xué)下冊一元一次不等式組的解法及應(yīng)用教案
安裝及運輸費用為600x＋800(12－x)，根據(jù)題意得4000x＋3000（12－x）≤40000，600x＋800（12－x）≤9200.解得2≤x≤4，由于x取整數(shù)，所以x＝2，3，4.答：有三種方案：①購買甲種設(shè)備2臺，乙種設(shè)備10臺；②購買甲種設(shè)備3臺，乙種設(shè)備9臺；③購買甲種設(shè)備4臺，乙種設(shè)備8臺．方法總結(jié)：列不等式組解應(yīng)用題時，一般只設(shè)一個未知數(shù)，找出兩個或兩個以上的不等關(guān)系，相應(yīng)地列出兩個或兩個以上的不等式組成不等式組求解．在實際問題中，大部分情況下應(yīng)求整數(shù)解．三、板書設(shè)計1．一元一次不等式組的解法2．一元一次不等式組的實際應(yīng)用利用一元一次不等式組解應(yīng)用題關(guān)鍵是找出所有可能表達(dá)題意的不等關(guān)系，再根據(jù)各個不等關(guān)系列成相應(yīng)的不等式，組成不等式組．在教學(xué)時要讓學(xué)生養(yǎng)成檢驗的習(xí)慣，感受運用數(shù)學(xué)知識解決問題的過程，提高實際操作能力.
北師大初中七年級數(shù)學(xué)下冊同底數(shù)冪的除法教案
【類型四】 含整數(shù)指數(shù)冪、零指數(shù)冪與絕對值的混合運算計算：－22＋(－12)－2＋(2015－π)0－|2－π2|.解析：分別根據(jù)有理數(shù)的乘方、零指數(shù)冪、負(fù)整數(shù)指數(shù)冪及絕對值的性質(zhì)計算出各數(shù)，再根據(jù)實數(shù)的運算法則進(jìn)行計算．解：－22＋(－12)－2＋(2015－π)0－|2－π2|＝－4＋4＋1－2＋π2＝π2－1.方法總結(jié)：熟練掌握有理數(shù)的乘方、零指數(shù)冪、負(fù)整數(shù)指數(shù)冪及絕對值的性質(zhì)是解答此題的關(guān)鍵．三、板書設(shè)計1．同底數(shù)冪的除法法則：同底數(shù)冪相除，底數(shù)不變，指數(shù)相減．2．零次冪：任何一個不等于零的數(shù)的零次冪都等于1.即a0＝1(a≠0)．3．負(fù)整數(shù)次冪：任何一個不等于零的數(shù)的－p(p是正整數(shù))次冪，等于這個數(shù)p次冪的倒數(shù)．即a－p＝1ap(a≠0，p是正整數(shù))．從計算具體問題中的同底數(shù)冪的除法，逐步歸納出同底數(shù)冪除法的一般性質(zhì)．教學(xué)時要多舉幾個例子，讓學(xué)生從中總結(jié)出規(guī)律，體驗自主探究的樂趣和數(shù)學(xué)學(xué)習(xí)的魅力，為以后的學(xué)習(xí)奠定基礎(chǔ)
北師大初中八年級數(shù)學(xué)下冊分式方程的解法教案
【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，此方程無解，此時m＝1；②方程有增根，則x＝2或x＝－2，當(dāng)x＝2時，代入(m－1)x＝－10得(m－1)×2＝－10，m＝－4；當(dāng)x＝－2時，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．2．分式方程的增根(1)解分式方程為什么會產(chǎn)生增根；(2)分式方程檢驗的方法．
北師大初中八年級數(shù)學(xué)下冊一元一次不等式的解法教案
方法總結(jié)：已知解集求字母系數(shù)的值，通常是先解含有字母的不等式，再利用解集唯一性列方程求字母的值．解題過程體現(xiàn)了方程思想．三、板書設(shè)計1．一元一次不等式的概念2．解一元一次不等式的基本步驟：(1)去分母；(2)去括號；(3)移項；(4)合并同類項；(5)兩邊都除以未知數(shù)的系數(shù)．本節(jié)課通過類比一元一次方程的解法得到一元一次不等式的解法，讓學(xué)生感受到解一元一次不等式與解一元一次方程只是在兩邊都除以未知數(shù)的系數(shù)這一步時有所不同．如果這個系數(shù)是正數(shù)，不等號的方向不變；如果這個系數(shù)是負(fù)數(shù)，不等號的方向改變．這也是這節(jié)課學(xué)生容易出錯的地方．教學(xué)時要大膽放手，不要怕學(xué)生出錯，通過學(xué)生犯的錯誤引起學(xué)生注意，理解產(chǎn)生錯誤的原因，以便在以后的學(xué)習(xí)中避免出錯.
