四年級(jí)下學(xué)期數(shù)學(xué)教學(xué)計(jì)劃

1、 四年級(jí)下學(xué)期數(shù)學(xué)教學(xué)計(jì)劃 一、制定計(jì)劃的目的： 本冊(cè)教材根據(jù)學(xué)生的年齡特點(diǎn)和生活經(jīng)驗(yàn)，選取了反映社會(huì)生活的內(nèi)容為素材，目的是有計(jì)劃的引導(dǎo)學(xué)生了解生活，認(rèn)識(shí)社會(huì)，進(jìn)一步體驗(yàn)數(shù)學(xué)學(xué)習(xí)的內(nèi)容是現(xiàn)實(shí)的、有價(jià)值的和富有挑戰(zhàn)性的。使學(xué)生通過觀察、思考、動(dòng)手實(shí)踐等等一系列學(xué)習(xí)活動(dòng)，在獲得數(shù)學(xué)知識(shí)的同時(shí)，增強(qiáng)對(duì)其他領(lǐng)域知識(shí)的了解。這樣的教材，有利于引導(dǎo)學(xué)生在探究數(shù)學(xué)知識(shí)的同時(shí)，增長(zhǎng)多方面的知識(shí)。加深對(duì)乘法分配律的理解，感受乘法分配律的作用，有效的提高課堂學(xué)習(xí)效率。又如，教材把“用字母表示數(shù)”安排在加法運(yùn)算率、乘法運(yùn)算率之前，在學(xué)習(xí)運(yùn)算律時(shí)能運(yùn)用字母簡(jiǎn)潔表示運(yùn)算率，有效的降低學(xué)生記憶運(yùn)算律的負(fù)擔(dān)，體會(huì)用字母表

2、達(dá)運(yùn)算律的優(yōu)越性，激發(fā)他們學(xué)習(xí)用字母表示數(shù)的積極性。大膽鼓勵(lì)學(xué)生自己提出問題、資助探索，為學(xué)生個(gè)性發(fā)展提供了較大的空間，在探究求“平均數(shù)”的方法時(shí)，教材充分放手讓學(xué)生采用自己的方法探討問題，可能有的會(huì)用“一朵不少”的方法，有的會(huì)用先求和再均分的方法。這樣設(shè)計(jì)，對(duì)學(xué)生經(jīng)理、體會(huì)探究問題的歷程是很有益的。 二、教學(xué)目標(biāo) 本冊(cè)教材經(jīng)歷數(shù)與代數(shù)、空間與圖形、統(tǒng)計(jì)與概率、實(shí)踐活動(dòng)與綜合運(yùn)用等構(gòu)成知識(shí)網(wǎng)。學(xué)生經(jīng)歷從具體實(shí)例中抽象出對(duì)稱、平移與旋轉(zhuǎn)的過程，認(rèn)識(shí)多邊形的面積等等。學(xué)會(huì)同時(shí)對(duì)兩種數(shù)量分段統(tǒng)計(jì)數(shù)據(jù)，能根據(jù)統(tǒng)計(jì)結(jié)果做出簡(jiǎn)單的判斷和預(yù)測(cè)。在統(tǒng)計(jì)過程中，逐步形成自主探索與合作交流的意識(shí)和能力，初步體會(huì)統(tǒng)

3、計(jì)的工具性。 三、教材分析： 本冊(cè)內(nèi)容包括：簡(jiǎn)易方程、多邊形的面積、綜合應(yīng)用關(guān)注我們的活動(dòng)空間、因數(shù)與倍數(shù)、分?jǐn)?shù)的意義和性質(zhì)、對(duì)成、平移與旋轉(zhuǎn)、分?jǐn)?shù)加減法（一）、綜合應(yīng)用我能長(zhǎng)多高、統(tǒng)計(jì)、可能性。 四、 教學(xué)措施： 在整冊(cè)教學(xué)中應(yīng)從以下幾個(gè)方面進(jìn)行教學(xué)及應(yīng)注意的幾個(gè)問題： 1、概念教學(xué)要聯(lián)系實(shí)際，加強(qiáng)探索性，讓學(xué)生在體驗(yàn)過程中加深對(duì)知識(shí)的理解。本冊(cè)教材概念性的知識(shí)比較多，如何優(yōu)化教學(xué)過程，提高教學(xué)質(zhì)量，是教學(xué)中應(yīng)注意的一個(gè)問題。為此，教師要注意在概念只是的教學(xué)中要聯(lián)系生活實(shí)際，挖掘?qū)W生身邊的教學(xué)資源，組織學(xué)生進(jìn)行探索性學(xué)習(xí)活動(dòng)，促進(jìn)學(xué)生對(duì)概念的理解和內(nèi)化。 2、加強(qiáng)簡(jiǎn)易方程之間的數(shù)量關(guān)系的教學(xué)

4、，使學(xué)生形成初步的代數(shù)意識(shí)。用x表示數(shù)和數(shù)量關(guān)系，是代數(shù)的一個(gè)基本特征，同時(shí)也是學(xué)生由算術(shù)思維向代數(shù)思維轉(zhuǎn)變的開端。在具體教學(xué)中，教師要?jiǎng)?chuàng)設(shè)問題情境，引導(dǎo)學(xué)生在解決實(shí)際問題的過程中，促進(jìn)概念的形成。 3、把握好動(dòng)手實(shí)踐的“度”，開展有效操作活動(dòng)。 “動(dòng)手操作”作為自主學(xué)習(xí)的一種重要學(xué)習(xí)方式，已普遍被老師接受。這就要求教師注意把握好操作的時(shí)機(jī)，在認(rèn)知的生長(zhǎng)處及思維的發(fā)散處開展操作活動(dòng)，使操作、觀察、思維及語言表達(dá)有機(jī)結(jié)合，真正起到深化認(rèn)知的作用。 4、 用好教材，做教材“再開發(fā)”得智者。 5、重視小數(shù)口算、估算的平日練習(xí)，小數(shù)四則運(yùn)算已全部學(xué)完。 6、全面、合理地評(píng)價(jià)學(xué)生的學(xué)習(xí)情況。 要關(guān)注學(xué)生

5、解決問題的獨(dú)立性、克服性，根據(jù)數(shù)據(jù)提出和解決問題的質(zhì)量，要關(guān)注學(xué)生克服困難的毅力和靈活解決問題的能力等，既是對(duì)學(xué)生的表現(xiàn)進(jìn)行評(píng)價(jià)，增強(qiáng)學(xué)習(xí)的信心。qcwa3ptgz7r4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgshls50clmtwn60eo8wgqv7xav2ohum32wgeauwydiawgmer4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgz7r4i30ka1dkagtgkqcwa3p tgz7r4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92t
