小學(xué)數(shù)學(xué)人教版二年級(jí)下冊(cè)《用有余數(shù)的除法解決問題》說課稿
一、設(shè)計(jì)思路《數(shù)學(xué)課程標(biāo)準(zhǔn)》倡導(dǎo)尊重學(xué)生的主觀能動(dòng)性，以自主探究、合作交流為主要學(xué)習(xí)方式。因此，在本節(jié)課中我們充分體現(xiàn)了以學(xué)生為主體的設(shè)計(jì)理念，采用具有我校特色的高效課堂模式“三學(xué)五環(huán)”教學(xué)法，學(xué)生以“自主學(xué)習(xí)-合作探究”的方式進(jìn)行學(xué)習(xí)，從而展示三學(xué)“獨(dú)學(xué)、對(duì)學(xué)、群學(xué)”。在教學(xué)流程上以：“情境導(dǎo)入，引入示標(biāo)；自主嘗試；交流展示；精講點(diǎn)撥；當(dāng)堂檢測(cè)”這五大環(huán)節(jié)來引領(lǐng)學(xué)生進(jìn)入知識(shí)的殿堂。二、說教材充分領(lǐng)略教材編排意圖，科學(xué)精當(dāng)?shù)胤治鑫谋?，是采用“以學(xué)定教”，實(shí)現(xiàn)“有效教學(xué)”的第一步?！队糜杏鄶?shù)除法解決問題》是人教版小學(xué)數(shù)學(xué)二年級(jí)下冊(cè)第67頁的內(nèi)容，它屬于數(shù)與代數(shù)領(lǐng)域。本節(jié)課是在學(xué)生已經(jīng)學(xué)習(xí)了表內(nèi)除法、用豎式計(jì)算除法、有余數(shù)除法的基礎(chǔ)上進(jìn)行教學(xué)的。同時(shí)，本課為今后學(xué)習(xí)近似數(shù)、估算進(jìn)行了初步的鋪墊。
小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《異分母分?jǐn)?shù)加減法》說課稿
重難點(diǎn)依據(jù)人教版數(shù)學(xué)教材新課程標(biāo)準(zhǔn)，在吃透教材的基礎(chǔ)上，我確定了掌握異分母分?jǐn)?shù)加減法的計(jì)算法則為教學(xué)重點(diǎn)，因?yàn)橹挥姓莆樟擞?jì)算法則，才能進(jìn)行計(jì)算。同時(shí)，也確定了理解異分母分?jǐn)?shù)加減法計(jì)算時(shí)必須先通分的算理為教學(xué)難點(diǎn)。 二、說教法我們都知道數(shù)學(xué)是中國教育中一門必修學(xué)科，因此，從小學(xué)數(shù)學(xué)教學(xué)開始，就不僅要使學(xué)生“知其然”，還要使學(xué)生“知其所以然”。我們?cè)谝詭熒葹橹黧w又為客體的原則下，展現(xiàn)獲取理論知識(shí)、解決實(shí)際問題的思維過程。考慮到五年級(jí)學(xué)生的現(xiàn)狀，我主要采取設(shè)置情景教學(xué)法，讓學(xué)生積極主動(dòng)地參與教學(xué)活動(dòng)，使他們?cè)诨顒?dòng)中得到認(rèn)識(shí)和體驗(yàn)，產(chǎn)生踐行的愿望。當(dāng)然老師自身也是非常重要的教學(xué)資源。教師本人應(yīng)該通過課堂教學(xué)感染和激勵(lì)學(xué)生，調(diào)動(dòng)起學(xué)生參與的積極性，激發(fā)學(xué)生對(duì)解決實(shí)際問題的渴望，并且要培養(yǎng)學(xué)生理論聯(lián)系實(shí)際的能力，從而達(dá)到最佳的教學(xué)效果。
小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《長方體和正方體的表面積》說課稿
一、教材分析長方體和正方體的表面積是人教版教材五年級(jí)下冊(cè)第三單元第二章節(jié)的內(nèi)容。本節(jié)課的地位和作用：這部分內(nèi)容是在學(xué)生學(xué)習(xí)了長方體和正方體的認(rèn)識(shí)以及掌握了長方形和正方形面積的計(jì)算方法的基礎(chǔ)上進(jìn)行教學(xué)。教材中各年級(jí)涉及到的內(nèi)容如下：長方體和正方體的表面積這部分內(nèi)容，是在學(xué)生認(rèn)識(shí)并掌握了長方體和正方體特征的基礎(chǔ)上教學(xué)的。教材為了使學(xué)生更好地建立表面積的概念，加強(qiáng)了動(dòng)手操作，讓每個(gè)學(xué)生拿一個(gè)長方體或正方體紙盒，沿著棱剪開，再展開，觀察展開后的形狀。并分別用“上”“下”“前”“后”“左”“右”標(biāo)明6個(gè)面。這樣，可以使學(xué)生把展開后每個(gè)面與展開前這個(gè)面的位置聯(lián)系起來，更清楚地看出長方體相對(duì)的面的面積相等，以及每個(gè)面的長和寬與長方體的長、寬、高之間的關(guān)系，既讓學(xué)生明確了表面積的含義，又為下面學(xué)習(xí)計(jì)算長方體和正方體的表面積做好了準(zhǔn)備。
小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《容積和容積單位》說課稿
因此，我從學(xué)生已有的生活出發(fā)，尋找例子，幫助學(xué)生理解容積的概念。同時(shí)也多次提供了實(shí)踐機(jī)會(huì)，讓學(xué)生自己操作實(shí)驗(yàn)的過程，在操作中感知1升、1毫升的大小和容積單位和體積單位之間的關(guān)系。二、說教學(xué)目標(biāo)1、理解容積的概念，認(rèn)識(shí)常用的容積單位，感知1升和1毫升的實(shí)際大小，并掌握容積單位、體積單位間的進(jìn)率。2、通過實(shí)驗(yàn)的方法，使學(xué)生經(jīng)歷探究容積單位、容積單位和體積單位之間的關(guān)系的過程。三、教學(xué)重難點(diǎn)：1、建立容積和容積單位概念，知道容積單位和體積單位的關(guān)系。2、會(huì)計(jì)算容積。四、說教法為了使課堂的主人能活躍起來，我用了自主探究式發(fā)現(xiàn)問題、談?wù)摻涣骱蛯?shí)驗(yàn)教學(xué)的方法進(jìn)行教學(xué)，從而也激發(fā)了學(xué)生的積極性和主動(dòng)性。五、說學(xué)法：更多的是引導(dǎo)學(xué)生在自主嘗試、觀察、討論和探究中獲取知識(shí)。
小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《長方體和正方體的認(rèn)識(shí)》說課稿
3.說教學(xué)重、難點(diǎn)依據(jù)數(shù)學(xué)課程標(biāo)準(zhǔn)，及對(duì)教材的認(rèn)識(shí)，我確定了本節(jié)課的重點(diǎn)和難點(diǎn)。教學(xué)重點(diǎn)：掌握長方體和正方體的特征。教學(xué)難點(diǎn)：建立“立體圖形”的空間概念，了解長方體、正方體的關(guān)系。二、說教法根據(jù)幾何知識(shí)的教學(xué)特點(diǎn)、本節(jié)教學(xué)內(nèi)容以及小學(xué)生空間觀念薄弱的特點(diǎn)，我將采用以下教學(xué)方法。直觀演示法：利用圖片等手段進(jìn)行直觀演示，激發(fā)學(xué)生的學(xué)習(xí)興趣；觀察發(fā)現(xiàn)法：通過讓學(xué)生觀察長方體、正方體的一些實(shí)物發(fā)現(xiàn)新知，培養(yǎng)學(xué)生的觀察概括能力；合作探究法：引導(dǎo)學(xué)生通過自主研究、合作討論等活動(dòng)形式來獲取知識(shí)。同時(shí)運(yùn)用多媒體輔助教學(xué)，使學(xué)生的觀察能力、抽象概括能力逐步提高。三、說學(xué)法為了使學(xué)生較好地掌握長方體和正方體的特征，并逐步形成空間觀念，除了讓學(xué)生通過觀察來認(rèn)識(shí)長方體和正方體的特征以外，在觀察實(shí)物的基礎(chǔ)上，通過動(dòng)手操作，看一看，摸一摸，數(shù)一數(shù)，量一量，做一做來學(xué)習(xí)新知，同時(shí)以此來激發(fā)學(xué)生的學(xué)習(xí)興趣，調(diào)動(dòng)學(xué)生的積極性。

1、教材分析《同分母分?jǐn)?shù)加減法》是人教版五年級(jí)下冊(cè)第五單元的內(nèi)容。本節(jié)教學(xué)內(nèi)容包括分?jǐn)?shù)加減法的含義、同分母分?jǐn)?shù)加減法的計(jì)算方法和連加、連減三個(gè)部分。這部分內(nèi)容是在學(xué)生學(xué)習(xí)整數(shù)、小數(shù)加減法的意義及其計(jì)算方法，分?jǐn)?shù)的意義和性質(zhì)，以及在三年級(jí)上冊(cè)學(xué)過的簡單的同分母分?jǐn)?shù)加減法的基礎(chǔ)上進(jìn)行教學(xué)的。為異分母分?jǐn)?shù)加減法的學(xué)習(xí)搭好階梯。2、學(xué)情分析相對(duì)整數(shù)加減運(yùn)算而言，分?jǐn)?shù)的加減運(yùn)算對(duì)于大多數(shù)學(xué)生來說是比較困難的，但是學(xué)生對(duì)簡單的同分母分?jǐn)?shù)加減法計(jì)算有一定基礎(chǔ)。學(xué)生已有一定的生活經(jīng)驗(yàn)，并有一定的分析和解決問題的能力，會(huì)有條理地表達(dá)自己的思考過程。3、教學(xué)目標(biāo)(1)知識(shí)與技能：掌握同分母分?jǐn)?shù)加減法的計(jì)算方法，理解相同單位的數(shù)相加減的算理及含義，并能夠正確熟練地計(jì)算。(2)過程與方法：能夠利用所學(xué)知識(shí)解決生活中的實(shí)際問題，培養(yǎng)學(xué)生應(yīng)用知識(shí)的能力。(3)情感態(tài)度與價(jià)值觀：通過小組合作學(xué)習(xí)，培養(yǎng)學(xué)生的合作意識(shí)和學(xué)好數(shù)學(xué)的信心。

思考：洗衣機(jī)脫水時(shí)轉(zhuǎn)速高時(shí)容易甩干衣物，還是轉(zhuǎn)速低時(shí)容易甩干衣物？(2) 制作棉花糖的原理內(nèi)筒與洗衣機(jī)的脫水筒相似，里面加入白砂糖，加熱使糖熔化成糖汁。內(nèi)筒高速旋轉(zhuǎn)，黏稠的糖汁就做離心運(yùn)動(dòng)，從內(nèi)筒壁的小孔飛散出去，成為絲狀到達(dá)溫度較低的外筒，并迅速冷卻凝固，變得纖細(xì)雪白，像一團(tuán)團(tuán)棉花。5.離心現(xiàn)象的防止在水平公路上行駛的汽車，轉(zhuǎn)彎時(shí)所需的向心力是由車輪與路面的靜摩擦力提供的。如果轉(zhuǎn)彎時(shí)速度過大，所需向心力F大于最大靜摩擦力Fmax，汽車將做離心運(yùn)動(dòng)而造成交通事故。因此，在公路彎道處，車輛行駛不允許超過規(guī)定的速度。當(dāng)高速轉(zhuǎn)動(dòng)的砂輪或者飛輪內(nèi)部分子間相互作用力不足以提供所需向心力時(shí)，離心運(yùn)動(dòng)就會(huì)使他們破裂，甚至釀成事故。

（二）進(jìn)行新課1、動(dòng)能與勢(shì)能的相互轉(zhuǎn)化演示實(shí)驗(yàn)1：如右圖，用細(xì)線、小球、帶有標(biāo)尺的鐵架臺(tái)等做實(shí)驗(yàn)。把一個(gè)小球用細(xì)線懸掛起來，把小球拉到一定高度的A點(diǎn)，然后放開，小球在擺動(dòng)過程中，重力勢(shì)能和動(dòng)能相互轉(zhuǎn)化。我們看到，小球可以擺到跟A點(diǎn)等高的C點(diǎn)，如圖甲。如果用尺子在某一點(diǎn)擋住細(xì)線，小球雖然不能擺到C點(diǎn)，但擺到另一側(cè)時(shí)，也能達(dá)到跟A點(diǎn)相同的高度，如圖乙。問題：這個(gè)小實(shí)驗(yàn)中，小球的受力情況如何？各個(gè)力的做功情況如何？這個(gè)小實(shí)驗(yàn)說明了什么？學(xué)生觀察演示實(shí)驗(yàn)，思考問題，選出代表發(fā)表見解。小球在擺動(dòng)過程中受重力和繩的拉力作用。拉力和速度方向總垂直，對(duì)小球不做功；只有重力對(duì)小球能做功。實(shí)驗(yàn)證明，小球在擺動(dòng)過程中重力勢(shì)能和動(dòng)能在不斷轉(zhuǎn)化。在擺動(dòng)過程中，小球總能回到原來的高度。可見，重力勢(shì)能和動(dòng)能的總和保持不變。即機(jī)械能保持不變。
