得到13－8=這個算式后，我讓小朋友們想辦法，“13－8怎么算？你是怎樣想的？把你的想法告訴你小組的同學(xué)們?！庇捎谖沂怯弥v故事的形式引出這一問題的，因此在計算13－8時，小朋友們就被迫要自己想辦法去計算，而不能光借助情境圖去直接數(shù)出得數(shù)。這并不阻礙算法的多樣化，相反更好地實現(xiàn)了算法多樣化的目的，真正讓學(xué)生成為了數(shù)學(xué)學(xué)習(xí)的主人。為了增加這堂課的趣味性，我有意將學(xué)生說出來的各種算法分別以他們的名字來命名，這樣一來，學(xué)生興趣盎然，都積極投入到了尋找算法的思考活動中來了。在尋求多樣化的過程中，充分發(fā)揮了學(xué)生學(xué)習(xí)的主體性，培養(yǎng)了學(xué)生的創(chuàng)新精神，讓每一個學(xué)生都能體驗學(xué)習(xí)的成功。學(xué)生們在思考、討論中可能會出現(xiàn)這樣幾種算法：

一、說教材分析教材分析：本部分內(nèi)容是在學(xué)生認(rèn)識了認(rèn)數(shù)的第一階段—20以內(nèi)各數(shù)認(rèn)識的基礎(chǔ)上，擴(kuò)展到認(rèn)數(shù)的第二階段—100以內(nèi)各數(shù)的認(rèn)識。本階段的數(shù)概念不僅是學(xué)習(xí)100以內(nèi)數(shù)計算的基礎(chǔ)，也是認(rèn)識更大的自然數(shù)的基礎(chǔ)。它在日常生活中有著廣泛的應(yīng)用，因此必須使學(xué)生切實學(xué)好。在分析教材的基礎(chǔ)上，靈活的運用教材，我認(rèn)為開始的主題圖，如果10只一群地出示，雖然有利于學(xué)生估數(shù)，但這樣學(xué)生能很快地10只10只地數(shù)出羊群只數(shù)是100，在后面數(shù)100個物體的個數(shù)時，就會受其影響而10個10個地數(shù)，這樣的數(shù)法，要在學(xué)生會逐個數(shù)數(shù)的基礎(chǔ)上自然生成，其實，它比一個一個地數(shù)要高一個層次，數(shù)數(shù)單位由“一”變成了“十”，不利于學(xué)生把100以內(nèi)的數(shù)逐個數(shù)出來，因此，我把主題圖的出示放在了一個一個數(shù)物體之后。

1．統(tǒng)計是數(shù)學(xué)課程標(biāo)準(zhǔn)規(guī)定的四個領(lǐng)域之一。傳統(tǒng)上比較注重統(tǒng)計圖表等知識和根據(jù)統(tǒng)計圖表回答問題的教學(xué)，而課程標(biāo)準(zhǔn)則更加重視學(xué)生對數(shù)據(jù)統(tǒng)計過程的體驗，學(xué)習(xí)一些簡單的收集、整理和描述數(shù)據(jù)的方法，認(rèn)識統(tǒng)計的作用和意義。這部分內(nèi)容比較繁瑣，分小組進(jìn)行合作學(xué)習(xí)是有效的學(xué)習(xí)方式。2．教師將教科書的盆花變成紙花，努力為學(xué)生創(chuàng)設(shè)一些數(shù)據(jù)，使教材更具有實用性。但是，對于有條件的學(xué)校，可以帶領(lǐng)學(xué)生進(jìn)行實地統(tǒng)計，效果會更佳。3．教師要善于捕捉課堂上學(xué)生的反饋信息，創(chuàng)設(shè)輕松愉悅的課堂氣氛。本課中，教師設(shè)計的讓學(xué)生學(xué)四種動物的叫聲，不僅活躍了課堂氣氛，又引入到下一個問題的探討。4．充分尊重學(xué)生的選擇，讓學(xué)生用自己喜歡的方法進(jìn)行統(tǒng)計，使他們的情感、態(tài)度在其中得到了充分體驗。
