北師大初中七年級數(shù)學(xué)上冊科學(xué)記數(shù)法教案1
解析：水是生命之源，節(jié)約水資源是我們每個居民都應(yīng)有的意識.題中給出假如每人浪費一點水，當(dāng)人數(shù)增多時，將是一個非常驚人的數(shù)字，100萬人每天浪費的水資源為1000000×0.32＝320000（升）.所以320000＝3.2×105.故選B.方法總結(jié)：從實際問題入手讓學(xué)生體會科學(xué)記數(shù)法的實際應(yīng)用.題中沒有直接給出數(shù)據(jù)，應(yīng)先計算，再表示.探究點二：將用科學(xué)記數(shù)法表示的數(shù)轉(zhuǎn)換為原數(shù)已知下列用科學(xué)記數(shù)法表示的數(shù)，寫出原來的數(shù)：（1）2.01×104；（2）6.070×105.解析：（1）將2.01的小數(shù)點向右移動4位即可；（2）將6.070的小數(shù)點向右移動5位即可.解：（1）2.01×104＝20100；（2）6.070×105＝607000.方法總結(jié)：將科學(xué)記數(shù)法a×10n表示的數(shù)，“還原”成通常表示的數(shù)，就是把a的小數(shù)點向右移動n位所得到的數(shù).三、板書設(shè)計借助身邊熟悉的事物進一步體會大數(shù)，積累數(shù)學(xué)活動經(jīng)驗，發(fā)展數(shù)感、空間感，培養(yǎng)學(xué)生自主學(xué)習(xí)的能力.
