因此，本套教材中刪去了“整除”的數(shù)學(xué)化定義，而是借助整除的模式na＝b直接引出因數(shù)和倍數(shù)的概念。在本冊(cè)教材中，由于允許學(xué)生采用多樣的方法求最大公因數(shù)和最小公倍數(shù)，分解質(zhì)因數(shù)也失去了其不可或缺的作用，同時(shí)，也是為了減少這一單元的理論概念，教材不再把它作為正式教學(xué)內(nèi)容，而是作為一個(gè)補(bǔ)充知識(shí)，安排在“你知道嗎？”中進(jìn)行介紹。由于這部分內(nèi)容較為抽象，很難結(jié)合生活實(shí)例或具體情境來進(jìn)行教學(xué)，學(xué)生理解起來有一定的難度。在過去的教學(xué)中，一些教師往往忽視概念的本質(zhì)，而是讓學(xué)生死記硬背相關(guān)概念或結(jié)論，學(xué)生無法理清各概念間的前后承接關(guān)系，達(dá)不到融會(huì)貫通的程度。再加上有些教師在考核時(shí)使用一些偏題、難題，導(dǎo)致學(xué)生在學(xué)習(xí)這部分知識(shí)時(shí)覺得枯燥乏味，體會(huì)不到初等數(shù)論的抽象性、嚴(yán)密性和邏輯性，感受不到數(shù)學(xué)的魅力。所以在教學(xué)中應(yīng)注意以下兩點(diǎn): （1）加強(qiáng)對(duì)概念間相互關(guān)系的梳理，引導(dǎo)學(xué)生從本質(zhì)上理解概念，避免死記硬背。（2）由于本單元知識(shí)特有的抽象性，教學(xué)時(shí)要注意培養(yǎng)學(xué)生的抽象思維能力。

2.采用比較簡(jiǎn)便的方法，師生合作完成“數(shù)據(jù)的收集與整理（強(qiáng)調(diào)數(shù)據(jù)的準(zhǔn)確性），學(xué)生獨(dú)立完成“表格的填寫”。3.小組內(nèi)討論完成“表格的分析”。4.全班進(jìn)行反饋。（意在培養(yǎng)獨(dú)立收集、整理數(shù)據(jù)的能力，核對(duì)數(shù)據(jù)的準(zhǔn)確性，并且擴(kuò)大提問題的參與面，讓學(xué)生也能啟動(dòng)智慧、享受快樂；及時(shí)反饋信息，調(diào)整教學(xué)目標(biāo)）四、全課總結(jié)1.通過今天的學(xué)習(xí)，同學(xué)們有哪些收獲？2.應(yīng)用延伸。（課本第112頁練習(xí)二十二第1題）五、布置作業(yè)教后反思統(tǒng)計(jì)是日常生產(chǎn)生活中常用和實(shí)用的工具，因此統(tǒng)計(jì)也是小學(xué)生必備的能力之一。但是統(tǒng)計(jì)的教學(xué)較為枯燥無味，教師往往會(huì)輕視統(tǒng)計(jì)的教學(xué)，忽略學(xué)生能力方面的培養(yǎng)。在教學(xué)統(tǒng)計(jì)時(shí)，老師要激發(fā)學(xué)生學(xué)習(xí)統(tǒng)計(jì)的興趣，創(chuàng)造各種情景，加強(qiáng)學(xué)生統(tǒng)計(jì)中的動(dòng)手實(shí)踐操作訓(xùn)練，同時(shí)在實(shí)際生活中加以運(yùn)用，并逐步加大難度和密度，同時(shí)也需要知道，統(tǒng)計(jì)教學(xué)不要過分地浮夸，多給予學(xué)生統(tǒng)計(jì)的意義，使其明確學(xué)習(xí)的目的。
