    二、說教學(xué)目標: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。2、運用有余數(shù)除法的有關(guān)知識,聯(lián)系生活實際解決簡單的問題,體驗成功的喜悅。三、說教學(xué)重難點:1、讓學(xué)生經(jīng)歷試商的過程,積累試商的經(jīng)驗,逐步達到熟練程度。2、使學(xué)生理解和掌握有余數(shù)除法的試商方法。體會余數(shù)要比除數(shù)小。四、說教學(xué)方法:探究、自主合作交流。五、說教具:課件、六、說教學(xué)過程:由于二年級學(xué)生,他們活潑好動,爭強好勝,想象豐富,求知欲旺盛;學(xué)習(xí)責(zé)任感不斷增強,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,無意注意占主導(dǎo)地位,缺乏獨立思考能力,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)活動的興趣,培養(yǎng)良好的學(xué)習(xí)習(xí)慣,幫助他們逐步樹立自信、自尊、自律等積極心態(tài),是他們通過思考,提高自我認知能力,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化之處。下面我將詳細說說我的教學(xué)過程:

    二、學(xué)情分析對于學(xué)生來說,在認識角之前,已經(jīng)具備了有關(guān)角的感性經(jīng)驗。但是,低年級學(xué)生的認知規(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)容對于二年級學(xué)生來說比較抽象,接受起來較為困難。為了幫助學(xué)生更好的認識角,形成角的表象。我設(shè)計了一些貼近學(xué)生生活的數(shù)學(xué)活動,讓孩子在實踐活動中經(jīng)過獨立思考,合作探究去認識角,發(fā)現(xiàn)角,從而感受到生活中處處有角。三、教學(xué)目標及重難點依據(jù)《課標》的要求和教材的特點,結(jié)合學(xué)生的生活實際及年齡特征,我確定了如下的教學(xué)目標:1、結(jié)合生活情境,感受生活中處處有角,體會數(shù)學(xué)與生活的密切聯(lián)系。2、通過摸一摸、找一找、搭一搭、畫一畫、比一比等活動讓學(xué)生直觀地認識角,感受角的大小。
