某文具店一支鉛筆的售價為1.2元，一支圓珠筆的售價為2元.該店在“6·1兒童節(jié)”舉行文具優(yōu)惠售賣活動，鉛筆按原價打8折出售，圓珠筆按原價打9折出售，結(jié)果兩種筆共賣出60支，賣得金額87元.若設(shè)鉛筆賣出x支，則依題意可列得的一元一次方程為（ ）A.1.2×0.8x＋2×0.9（60＋x）＝87B.1.2×0.8x＋2×0.9（60－x）＝87C.2×0.9x＋1.2×0.8（60＋x）＝87D.2×0.9x＋1.2×0.8（60－x）＝87解析：設(shè)鉛筆賣出x支，根據(jù)“鉛筆按原價打8折出售，圓珠筆按原價打9折出售，結(jié)果兩種筆共賣出60支，賣得金額87元”，得出等量關(guān)系：x支鉛筆的售價＋（60－x）支圓珠筆的售價＝87，據(jù)此列出方程為1.2×0.8x＋2×0.9（60－x）＝87.故選B.方法總結(jié)：解題的關(guān)鍵是讀懂題意，設(shè)出未知數(shù)，找到題目當(dāng)中的等量關(guān)系，最后列方程.三、板書設(shè)計教學(xué)過程中，通過對多種實(shí)際問題情境的分析，感受方程作為刻畫現(xiàn)實(shí)世界有效模型的意義，通過觀察、歸納一元一次方程的概念，使學(xué)生在分析實(shí)際問題情境的活動中體會數(shù)學(xué)與現(xiàn)實(shí)的密切聯(lián)系.
北師大初中數(shù)學(xué)八年級上冊平面直角坐標(biāo)系2教案
3．想一想在例1中，（1）點(diǎn)B與點(diǎn)C的縱坐標(biāo)相同，線段BC的位置有什么特點(diǎn)？（2）線段CE位置有什么特點(diǎn)？（3）坐標(biāo)軸上點(diǎn)的坐標(biāo)有什么特點(diǎn)？由B（0，－3），C（3，－3）可以看出它們的縱坐標(biāo)相同，即B，C兩點(diǎn)到X軸的距離相等，所以線段BC平行于橫軸（x軸），垂直于縱軸（y軸）。第三環(huán)節(jié)學(xué)有所用.補(bǔ)充：1．在下圖中，確定A，B，C，D，E，F(xiàn)，G的坐標(biāo)。（第1題） （第2題）2．如右圖，求出A，B，C，D，E，F(xiàn)的坐標(biāo)。第四環(huán)節(jié)感悟與收獲1．認(rèn)識并能畫出平面直角坐標(biāo)系。2．在給定的直角坐標(biāo)系中，由點(diǎn)的位置寫出它的坐標(biāo)。3．能適當(dāng)建立直角坐標(biāo)系，寫出直角坐標(biāo)系中有關(guān)點(diǎn)的坐標(biāo)。4．橫（縱）坐標(biāo)相同的點(diǎn)的直線平行于y軸，垂直于x軸；連接縱坐標(biāo)相同的點(diǎn)的直線平行于x軸,垂直于y軸。5．坐標(biāo)軸上點(diǎn)的縱坐標(biāo)為0；縱坐標(biāo)軸上點(diǎn)的坐標(biāo)為0。6．各個象限內(nèi)的點(diǎn)的坐標(biāo)特征是：第一象限（＋，＋）第二象限（－，＋），第三象限（－，－）第四象限（＋，－）。
