Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

三、估算度的把握?！稑藴省吩谟嬎憬虒W方面強調的內容之一是重視估算，培養(yǎng)估算意識。我們認為重視估算，就是對學生數(shù)感的培養(yǎng)，具體體現(xiàn)在能估計運算的結果，并對結果的合理性作出解釋。本節(jié)課的設計就是讓學生在具體情境中，學會兩種估算方法，結合具體情況作出合理解釋。四、教會學生單元整理與復習的方法，使學生終身受益。我們知道授人以漁而非魚的道理。在本節(jié)課中，老師設計了引導學生學會整理與復習的方法，如：帶著問題看書，將算式分類、歸納、總結出本單元所學內容，計算方法，注意地方，最后進行有針對性的練習。如果我們的老師從小就有意識地對學生進行學習方法的培養(yǎng)，學生將終身受益。我想我們教學研討活動就是為了實現(xiàn)教育的最高境界：今天的教是為了明天的不教。

三、說教法、學法從素質教育著眼點來看，要貫徹傳授知識與培養(yǎng)能力相結合的原則，不僅要使學生學會知識，更要使學生會學、樂學、主動去學。為了更充分地發(fā)揮學生的主體地位，使他們能夠自主學習，切實提高課堂教學效率。在教學方法上，采用談話激趣、回憶交流、討論歸納、強化練習等教學方法，循循誘導，讓學生在比賽、游戲、練習、合作中自主學習，鞏固和拓展所學知識。四、說教學過程“將課堂還給學生，讓課堂煥發(fā)生命的活力”“努力營造學生在教學活動中自主學習的時間和空間”從這種設計理念出發(fā)，為了更好的達到教學目標，突出重點，增強教學效果，使學生計算能力得到真正發(fā)展，我對本節(jié)課設計如下幾個環(huán)節(jié)：（一）、激趣導入。同學們，這幾天我們一直在學習多位數(shù)乘一位數(shù)的知識，你們想不想知道我們今天要學習什么知識？

比較2和3兩個算式：這兩個算式的不同？請學生具體解釋一下270-180為什么要用括號？讓學生體會到解決問題的思路不同，解決方法也不同，計算的步數(shù)也是不同的。（再請學生分別說說這兩個算式的計算過程，每一步的含義。）小結：括號是用來改變運算順序的。當你列出的綜合算式的運算順序與實際需要的運算順序不相符時，就用括號來改變運算順序。比如（擦去（270-180）÷30中的括號）這樣的算式中先算什么？按照混合運算順序的規(guī)定是不能先算270-180的，要想先算這部分就要用括號把這一步括起來。這個算式才正確表示了我們解決問題的方法步驟。（設計意圖：在這個環(huán)節(jié)中，在自主探索的基礎上，教師給學生提供充分表達自己見解的機會，闡述自己得出的結論探究過程及疑難問題。然后根據(jù)學生反饋的信息，組織、引導學生通過個體發(fā)言、小組討論、辯論等多種形式進行辨析評價，使學生的認知結構更加穩(wěn)定和完善。）
人教版新課標小學數(shù)學五年級下冊整數(shù)加法的運算定律推廣到分數(shù)加法說課稿
（一）教學內容：我說課的內容是第5單元中內容，（二）教材地位：加法是數(shù)學中最基本的運算之一。從教材的縱向聯(lián)系來看，幾年前已學過整數(shù)加法和小數(shù)加法，以及加法的運算定律，知道它不僅適用于整數(shù)加法，而且也適用于小數(shù)加法。那么是否也適用于現(xiàn)在所學習的分數(shù)加法呢？這就是我們這節(jié)課要研究的問題，當然，結果是肯定的。通過本課的學習，將整數(shù)加法的運算定律推廣到分數(shù)加法，可使學生對加法的認識從感性上升到理性。為后面學習分數(shù)加法的簡便計算打好基礎，同時也為學習小數(shù)、分數(shù)混合運算奠定基礎。其次，將整數(shù)加法的運算定律推廣到分數(shù)加法，也拓展了加法運算定律的使用范圍，豐富其內涵。而且加法運算定律字母表示形式，為以后代數(shù)知識的學習奠定了初步基礎。
人教版新課標小學數(shù)學六年級上冊分數(shù)除法的意義和分數(shù)除以整數(shù)說課稿
師：這是一種較為簡便、應用廣泛的方法，但有時候也要具體問題具體分析，做題時要合理靈活地選擇計算方法。《研究學生如何學比研究教師如何教更重要。學生對新知識的學習必須以已有的知識和學習經驗作為基礎，因此正確分析學生的知識基礎和學習經驗就顯得格外重要。我認為分數(shù)除以整數(shù)的教學基礎在于以下幾點：分數(shù)與小數(shù)的轉化；分數(shù)的意義；分數(shù)乘法的意義；倒數(shù)的知識；商不變的性質等。這些知識在以前的學習中，學都有了足夠的掌握。有了上面的分析基礎，我覺得把研究新知識的權力教給學生，是完全可以的?！?、質疑與反思。師：對于這些方法，盡管大家的思維角度不盡相同，但是基本的想法是相同的，想一想我們是怎樣解決問題的？生：用學過的倒數(shù)、商不變的性質解決的。師：對。用一句話概括就是運用舊知識解決新新問題。這是一種很重要的學習方法。5、實踐體驗練習鞏固。
人教版新課標小學數(shù)學六年級上冊分數(shù)除法的意義和整數(shù)除以分數(shù)說課稿
一．說教材。我說課的內容是人教版課程標準實驗教科書六年級上冊的分數(shù)除法單元中的例1和例2。例1是分數(shù)除法的意義認識，例2是分數(shù)除以整數(shù)的計算。在這之前學生已經掌握了整數(shù)除法的意義和分數(shù)乘法的意義及計算，而本課的學習將為統(tǒng)一分數(shù)除法計算法則打下基礎。例1先是整數(shù)除法回顧，再由100克=1/10千克，從而引出分數(shù)除法算式，通過類比使學生認識到分數(shù)除法的意義與整數(shù)除法的意義相同，都是‘已知兩個因數(shù)的積和其中一個因數(shù)，求另一個因數(shù)的運算’。例2是分數(shù)除以整數(shù)的計算教學，意在通過讓學生進行折紙實驗、驗證，引導學生將‘圖’和‘式’進行對照分析，從而發(fā)現(xiàn)算法，感悟算理，同時也初步感受數(shù)形結合的思想方法。根據(jù)剛才對教材的理解，本節(jié)課的教學目標是：1、理解分數(shù)除法的意義與整數(shù)除法的意義相同。2．理解分數(shù)除以整數(shù)的計算原理，掌握計算方法，并能正確的進行計算。

1.師要注意區(qū)別教學內容是否適合進行小組合作探究。這種學習是否每節(jié)課都需要。學生的小組學習是否在走過場，或者說流于形式。教師要注意營造自由自在的學習氛圍，控制討論的局面，如討論中是否有人進行人身攻擊，是否有人壟斷發(fā)言權而有的人卻一言不發(fā)，是否有人竊竊私語，教師要在巡視及參與中“察言觀色”，及時調控。2.教師要充分注意精心設計的問題。教師的教學設計是否合適，是做秀還是教學的需要。這不僅需要教師的認同，還需要課程的認同，學生的認同。因此，對于適合采用小組合作探究方式的教學內容，我們一定要根據(jù)課程標準的三維目標學生現(xiàn)有的認知程度和興趣以及本課要解決的問題和教學任務來精心設計問題。3.要注重小組合作探究的組織,進行適當有效的指導。教師要轉換自己的角色，從傳授者變成指導者、參與者、監(jiān)控者和幫助者，并切實注意自身行為的方法和效果，及時進行調整。

1、、用多媒體幻燈片逐一出示各種圖片。創(chuàng)設問題情境。引導學生提出用乘法計算問題。內容：郵局郵票出售處，有的郵票一枚80分，有的郵票一枚60分。百貨商店鞋柜，一雙旅游鞋78元，一雙皮鞋164元。電影院售票處：日場一張電影票15元，夜場一張電影票20元。小袋鼠蹦跳一次約2米，小袋鼠蹦跳33次。文具商店柜臺，每合圖釘120個，每包日記本25本。2、出示教科書第70頁例2主題圖：三年紀一班29個同學去參觀航天航空展覽，門票每張8元。請學生提出問題，老師在學生提出問題的基礎上，補充提出如果老師這時只帶250元錢去夠嗎？二、嘗試解決。1、教師先請學生猜一猜帶250元夠不夠？再請學生思考怎么知道我們猜得對不對呢？看看小精靈是怎么說的？2、怎么才能知道8×29大約是多少呢？能不能用我們前面學過的計算方法來解決這個問題。3、啟發(fā)學生想出前面我們已經學過整十乘一位數(shù)的乘法口算。我們可以把29看成最接近的整十數(shù)來估算。
人教版新課標小學數(shù)學三年級下冊一位數(shù)除兩位數(shù)商是兩位數(shù)的筆算除法說課稿
一．教材分析本節(jié)課選自人教版數(shù)學教材三年級下冊第二單元《除數(shù)是一位數(shù)的除法》第二小節(jié)《筆算除法》的第一課時——《“一位數(shù)除兩位數(shù)商是兩位數(shù)”的筆算除法》。1.教材的特點、地位和作用：本節(jié)課是整數(shù)除法的相關知識，它是在口算除法和除法豎式的基礎上進行教學的，又為學生掌握除數(shù)是兩位數(shù)的除法、學習除數(shù)是多位數(shù)的除法奠定了扎實的知識和思維基礎。通過學習，讓學生在活動中理解筆算除法的算理，探索用豎式計算的合理程序。教科書安排了兩個例題，例1是一位數(shù)除兩位數(shù)，被除數(shù)的各個數(shù)位上的數(shù)都能被整除，主要解決除的順序和豎式寫法的問題；例2也是一位數(shù)除兩位數(shù)，但除到被除數(shù)十位上有余數(shù)。本節(jié)課內容，對學生進一步學習筆算除法有著非常重要的作用。2.教材的重點和難點：重點是理解算理，掌握算法．掌握筆算除法的步驟和商的書寫位置。難點是讓學生理解每求出一位商后，如果有余數(shù)，應該與下一位上的數(shù)連在一起繼續(xù)除的道理。
人教版新課標小學數(shù)學四年級下冊把高級單位改寫成低級單位：名數(shù)的改寫說課稿
一、教材分析：《名數(shù)的改寫》是四年級下冊小數(shù)的意義和性質的內容。該內容是在學生已經學習了利用小數(shù)點位置移動引起小數(shù)的大小變化規(guī)律的基礎上進行教學的。本信息窗呈現(xiàn)的是一只天鵝從出生到長大體重變化的情況。圖中用文字標出了具體的變化數(shù)據(jù)。主要通過引導學生解答天鵝體重變化的問題，讓學生體會到單位不相同，必須改寫成相同的單位，展開對名數(shù)改寫知識的學習。二、教學目標根據(jù)上述對教材的分析，考慮到學生已有的認知結構和心理特征，我確立了本課的教學目標為：知識與技能方面：會利用移動小數(shù)點的位置來進行名數(shù)改寫。理解知識間聯(lián)系，提高學生運用所學知識解決問題的能力。過程與方法方面：利用小數(shù)點位置移動引起小數(shù)大小變化的規(guī)律和名數(shù)改寫的基本方法，引導學生進行知識遷移，從而掌握利用小數(shù)點的位置移動進行名數(shù)改寫的方法。
