二、說教學(xué)目標(biāo)1、結(jié)合具體情境進(jìn)一步理解加減法的意義,能正確口算得數(shù)是百以內(nèi)數(shù)的兩位數(shù)加減法。2、能利用所學(xué)知識(shí),在教師的指導(dǎo)下提出并解決簡(jiǎn)單的實(shí)際問題,了解同一問題可以用不同的方法解決。3、經(jīng)歷與他人交流各自計(jì)算方法的過程,體驗(yàn)解決問題策略的多樣性,感受學(xué)數(shù)學(xué)、用數(shù)學(xué)的樂趣。三、說教法、學(xué)法教法:為了使學(xué)生掌握好百以內(nèi)的兩位數(shù)加減兩位數(shù)的口算這部分知識(shí),達(dá)到以上教學(xué)目的,突破以上教學(xué)重難點(diǎn),我采用了遷移法、引導(dǎo)法、講解法、聯(lián)系法、自主探索法來進(jìn)行教學(xué)。學(xué)法:通過本課的學(xué)習(xí),使學(xué)生學(xué)會(huì)利用舊知構(gòu)建新知的方法、合作探究的方法,調(diào)動(dòng)學(xué)生主動(dòng)探索的積極性。四、說教學(xué)過程(一)創(chuàng)設(shè)情景、導(dǎo)入新課1、談話:同學(xué)們,大千世界無奇不有。我們所處的人類的社會(huì)是由一個(gè)個(gè)擔(dān)任不同工作的人所組成的,而和我們生活密切相關(guān)的蜜蜂也跟人類一樣,它們生活在一個(gè)蜜蜂王國(guó)里,今天我們就一起到那里了解一下蜜蜂的生活吧。
(四)、課堂總結(jié)、體驗(yàn)成功引導(dǎo)學(xué)生對(duì)所學(xué)知識(shí)、學(xué)習(xí)方法、學(xué)習(xí)結(jié)果、情感等進(jìn)行全面總結(jié),讓學(xué)生體驗(yàn)學(xué)習(xí)的成功感,同時(shí),進(jìn)一步系統(tǒng)、完善知識(shí)結(jié)構(gòu)??傊?,本課的教學(xué)設(shè)計(jì)力求體現(xiàn)“以學(xué)生為本”的教學(xué)理念,具體體現(xiàn)在以下幾個(gè)方面:(一)、創(chuàng)設(shè)生動(dòng)的情景,激發(fā)探索的樂趣,讓學(xué)生感受數(shù)學(xué)與生活的聯(lián)系。課的引入以一幅學(xué)生經(jīng)常接觸的,喜聞樂見的購(gòu)買玩具這一題材為切入點(diǎn)。在練習(xí)設(shè)計(jì)中,改變枯燥抽象的數(shù)字計(jì)算練習(xí),選取了一組寓有童趣的素材。它們以豐富多彩的呈現(xiàn)方式深深地吸引著學(xué)生,使他們認(rèn)識(shí)到現(xiàn)實(shí)生活中蘊(yùn)含著大量的數(shù)學(xué)信息,使學(xué)生感到有趣、有挑戰(zhàn)性,激發(fā)他們好奇,好勝的心理,從而誘發(fā)他們?nèi)ブ鲃?dòng)尋求解決問題的策略,同時(shí)體驗(yàn)到數(shù)學(xué)與生活的聯(lián)系。
三、估算度的把握。《標(biāo)準(zhǔn)》在計(jì)算教學(xué)方面強(qiáng)調(diào)的內(nèi)容之一是重視估算,培養(yǎng)估算意識(shí)。我們認(rèn)為重視估算,就是對(duì)學(xué)生數(shù)感的培養(yǎng),具體體現(xiàn)在能估計(jì)運(yùn)算的結(jié)果,并對(duì)結(jié)果的合理性作出解釋。本節(jié)課的設(shè)計(jì)就是讓學(xué)生在具體情境中,學(xué)會(huì)兩種估算方法,結(jié)合具體情況作出合理解釋。四、教會(huì)學(xué)生單元整理與復(fù)習(xí)的方法,使學(xué)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(shè)計(jì)了引導(dǎo)學(xué)生學(xué)會(huì)整理與復(fù)習(xí)的方法,如:帶著問題看書,將算式分類、歸納、總結(jié)出本單元所學(xué)內(nèi)容,計(jì)算方法,注意地方,最后進(jìn)行有針對(duì)性的練習(xí)。如果我們的老師從小就有意識(shí)地對(duì)學(xué)生進(jìn)行學(xué)習(xí)方法的培養(yǎng),學(xué)生將終身受益。我想我們教學(xué)研討活動(dòng)就是為了實(shí)現(xiàn)教育的最高境界:今天的教是為了明天的不教。
(6)交流。6的乘法口訣一共有幾句?口訣中的第一個(gè)數(shù)與算式中的第二個(gè)因數(shù)相同,表示什么?口訣中的第二個(gè)數(shù)與算式的第一個(gè)因數(shù)相同,表示什么?相鄰兩句口訣的積相差幾?哪幾句難記一些?你用什么方法記呢?怎樣記住"三六十八"、"四六二十四"兩句口訣?教師在學(xué)生發(fā)言的基礎(chǔ)上鼓勵(lì)學(xué)生大膽說、想出不同記口訣的方法。(7)應(yīng)用"做一做"第1題(學(xué)生半獨(dú)立完成):①用6根小棒擺1個(gè)六邊形;②擺2個(gè)六邊形要用多少根小棒?你是怎樣想的?(想口訣"二六十二"。)③運(yùn)用所學(xué)的口訣口答擺4個(gè)、6個(gè)、3個(gè)、5個(gè)六邊形所需要向小棒數(shù)。"做一做"第2題(獨(dú)立完成):①將第2題改為填空題,在圓圈內(nèi)填寫正確的積;②口答得數(shù),并說一說所用口訣。
