用米作單位，用分?jǐn)?shù)怎么表示呢？（1/10米）師：1/10米也可以寫(xiě)成0.1米。師：請(qǐng)同學(xué)們看米尺，從0到30，從0到70，應(yīng)該是幾分米，十分之幾米？用小數(shù)怎樣表示呢？可先和同桌商量商量。學(xué)生同桌討論后反饋師根據(jù)反饋結(jié)果提問(wèn)：請(qǐng)同學(xué)觀察一下1/10米和0.1米,3/10米和0.3米,7/10米和0.7米之間有什么關(guān)系?隨學(xué)生的回答出示1/10米=0.1米 3/10米=0.3米 7/10米=0.7米。再讓學(xué)生觀察上面的等式，四人小組討論你發(fā)現(xiàn)了什么？使學(xué)生通過(guò)討論明確：分母是10的分?jǐn)?shù)可以寫(xiě)成一位小數(shù)，一位小數(shù)表示十分之幾。2、 認(rèn)識(shí)兩位小數(shù) 、三位小數(shù)師：我們已經(jīng)知道了一位小數(shù)表示十分之幾，那么請(qǐng)同學(xué)猜一猜兩位小數(shù)與什么樣的分?jǐn)?shù)有關(guān)？三位小數(shù)與什么樣的分?jǐn)?shù)有關(guān)？（具體的步驟和前面相似）讓學(xué)生根據(jù)一位小數(shù)表示十分之幾，猜想出兩位小數(shù)和什么樣的分?jǐn)?shù)有關(guān)？有意識(shí)地促進(jìn)“遷移”，使學(xué)生在學(xué)會(huì)的同時(shí)學(xué)習(xí)能力也得到提高。關(guān)于計(jì)數(shù)單位的教學(xué)我個(gè)人認(rèn)為還是放到52頁(yè)小數(shù)數(shù)位順序表這里教學(xué)比較妥當(dāng)。
