[教材分析]本課時(shí)是《克和千克》這一單元的第一節(jié)課，主要介紹一些普通生活用品的重量認(rèn)識(shí)質(zhì)量單位克和千克，培養(yǎng)學(xué)生用數(shù)學(xué)觀點(diǎn)發(fā)現(xiàn)克和千克兩個(gè)質(zhì)量單位，為進(jìn)一步學(xué)習(xí)有關(guān)克和千克之間的聯(lián)系做好準(zhǔn)備。[學(xué)情分析]對(duì)于活潑好動(dòng)的二年級(jí)孩子來(lái)說(shuō)，物體的重量他們有一定的生活體驗(yàn)，同時(shí)，二年級(jí)學(xué)生形象思維能力較強(qiáng)，可以利用他們對(duì)身邊物體質(zhì)量來(lái)認(rèn)識(shí)克和千克。有了以上的認(rèn)識(shí)，我將本節(jié)課的教學(xué)目標(biāo)擬定為：[目標(biāo)定位]1、知識(shí)目標(biāo)：讓學(xué)生在生動(dòng)活潑的情境中初步認(rèn)識(shí)克和千克，建立克和千克的觀念，知道1000克=1千克2、能力目標(biāo)：培養(yǎng)學(xué)生初步的觀察、操作能力，讓學(xué)生學(xué)會(huì)看秤培養(yǎng)動(dòng)手能力。3、情感目標(biāo)：培養(yǎng)學(xué)生自主探索的精神和增強(qiáng)生活意識(shí)。教學(xué)重難點(diǎn)：通過(guò)活動(dòng)正確認(rèn)識(shí)克和千克的關(guān)系，知道1克和1千克的關(guān)系，難點(diǎn)建立克和千克的意識(shí)。

二、說(shuō)教學(xué)目標(biāo)：1、探索有余數(shù)除法的試商方法，讓學(xué)生再探索、練習(xí)中積累有余數(shù)除法的試商經(jīng)驗(yàn)。2、運(yùn)用有余數(shù)除法的有關(guān)知識(shí)，聯(lián)系生活實(shí)際解決簡(jiǎn)單的問(wèn)題，體驗(yàn)成功的喜悅。三、說(shuō)教學(xué)重難點(diǎn)：1、讓學(xué)生經(jīng)歷試商的過(guò)程，積累試商的經(jīng)驗(yàn)，逐步達(dá)到熟練程度。2、使學(xué)生理解和掌握有余數(shù)除法的試商方法。體會(huì)余數(shù)要比除數(shù)小。四、說(shuō)教學(xué)方法：探究、自主合作交流。五、說(shuō)教具：課件、六、說(shuō)教學(xué)過(guò)程：由于二年級(jí)學(xué)生，他們活潑好動(dòng)，爭(zhēng)強(qiáng)好勝，想象豐富，求知欲旺盛；學(xué)習(xí)責(zé)任感不斷增強(qiáng)，但學(xué)習(xí)往往從興趣出發(fā)；他們注意力不穩(wěn)定、不持久，無(wú)意注意占主導(dǎo)地位，缺乏獨(dú)立思考能力，容易受外界事物的干擾。因此，教學(xué)中培養(yǎng)學(xué)生參與數(shù)學(xué)活動(dòng)的興趣，培養(yǎng)良好的學(xué)習(xí)習(xí)慣，幫助他們逐步樹(shù)立自信、自尊、自律等積極心態(tài)，是他們通過(guò)思考，提高自我認(rèn)知能力，自我控制能力，這是提高課堂教學(xué)效益的基礎(chǔ)，也是教師需努力和強(qiáng)化之處。下面我將詳細(xì)說(shuō)說(shuō)我的教學(xué)過(guò)程：

二、學(xué)情分析對(duì)于學(xué)生來(lái)說(shuō)，在認(rèn)識(shí)角之前，已經(jīng)具備了有關(guān)角的感性經(jīng)驗(yàn)。但是，低年級(jí)學(xué)生的認(rèn)知規(guī)律是以具體的形象思維為主，抽象思維能力較低。這部分內(nèi)容對(duì)于二年級(jí)學(xué)生來(lái)說(shuō)比較抽象，接受起來(lái)較為困難。為了幫助學(xué)生更好的認(rèn)識(shí)角，形成角的表象。我設(shè)計(jì)了一些貼近學(xué)生生活的數(shù)學(xué)活動(dòng)，讓孩子在實(shí)踐活動(dòng)中經(jīng)過(guò)獨(dú)立思考，合作探究去認(rèn)識(shí)角，發(fā)現(xiàn)角，從而感受到生活中處處有角。三、教學(xué)目標(biāo)及重難點(diǎn)依據(jù)《課標(biāo)》的要求和教材的特點(diǎn)，結(jié)合學(xué)生的生活實(shí)際及年齡特征，我確定了如下的教學(xué)目標(biāo)：1、結(jié)合生活情境，感受生活中處處有角，體會(huì)數(shù)學(xué)與生活的密切聯(lián)系。2、通過(guò)摸一摸、找一找、搭一搭、畫(huà)一畫(huà)、比一比等活動(dòng)讓學(xué)生直觀地認(rèn)識(shí)角，感受角的大小。

解決了以上三個(gè)問(wèn)題以后，我再讓學(xué)生先獨(dú)立將四座山的高度按照從小到大的順序排列出來(lái)，這時(shí)，我會(huì)適當(dāng)?shù)匾龑?dǎo)學(xué)生閱讀前面三個(gè)問(wèn)題的解決過(guò)程，并梳理進(jìn)行多位數(shù)比較的思路：先按數(shù)位比，再?gòu)母呶豢雌?。（三）分層次練?xí)，鞏固新知識(shí)在學(xué)生掌握了上述比較大數(shù)的方法以后,我將讓學(xué)生運(yùn)用所學(xué)的新知識(shí),去解決”練一練”中的第1,2,5題。其中第1，2題是為了鞏固“萬(wàn)以?xún)?nèi)的數(shù)的比較方法”，“能用符號(hào)表示萬(wàn)以?xún)?nèi)數(shù)的大小”這兩個(gè)知識(shí)點(diǎn)；而第五題則是為了鼓勵(lì)學(xué)生在新的情景中，進(jìn)行數(shù)的大小比較。（四）課程總結(jié)這節(jié)課，同學(xué)們收獲了什么？學(xué)生一定會(huì)很輕易地將上面四座山進(jìn)行比較的規(guī)律說(shuō)出來(lái)的。這時(shí),我會(huì)引導(dǎo)學(xué)生回顧全文第四,板書(shū)設(shè)計(jì)(略)本節(jié)課，我將用最簡(jiǎn)單的文字體現(xiàn)重難點(diǎn)，便于學(xué)生理解。我的說(shuō)課到此結(jié)束，謝謝大家！
