小學(xué)數(shù)學(xué)人教版一年級下冊《100以內(nèi)數(shù)的大小比較》說課稿
尊敬的各位領(lǐng)導(dǎo)、老師：大家下午好！今天我說課的題目是《100以內(nèi)數(shù)的大小比較》，我將從教材、教法學(xué)法、教學(xué)流程、板書設(shè)計、教學(xué)反思五個方面來談一談。一、說教材1．教學(xué)內(nèi)容這節(jié)課是義務(wù)教育課程標(biāo)準(zhǔn)人教版實驗教科書，數(shù)學(xué)一年級下冊第四單元《100以內(nèi)數(shù)的認(rèn)識》中的例5“比較大小”。2．教材分析學(xué)生在此之前，已經(jīng)學(xué)習(xí)了20以內(nèi)各數(shù)的認(rèn)識及比較大小，這為過渡到本節(jié)課的學(xué)習(xí)起著鋪墊作用，“做一做”可以幫助學(xué)生進(jìn)一步鞏固比較兩個兩位數(shù)大小的方法。3．教學(xué)目標(biāo)為了實現(xiàn)“人人學(xué)有價值的數(shù)學(xué)，人人都獲得必須的數(shù)學(xué)，不同的人在數(shù)學(xué)上得到不同的發(fā)展。”我確定了如下的教學(xué)目標(biāo)：（1）利用現(xiàn)實有趣的情境激發(fā)學(xué)生的求知欲、學(xué)習(xí)數(shù)學(xué)的興趣。（2）培養(yǎng)學(xué)生觀察、比較、提出問題和解決問題的能力。
小學(xué)數(shù)學(xué)人教版四年級上冊《億以內(nèi)數(shù)的認(rèn)識》說課稿
三、教學(xué)理念：學(xué)生是數(shù)學(xué)學(xué)習(xí)的主人，教師是數(shù)學(xué)學(xué)習(xí)的組織者，引導(dǎo)者和合作者。教師要遵循兒童心理特點和認(rèn)知規(guī)律，加強(qiáng)數(shù)學(xué)與現(xiàn)實生活的聯(lián)系，關(guān)注學(xué)生個體差異，使學(xué)生人人學(xué)有價值的數(shù)學(xué)，人人能獲得必要的數(shù)學(xué)，不同的人在數(shù)學(xué)上得到不同的發(fā)展。在教師精心組織下，充分讓學(xué)生自己去發(fā)現(xiàn)探索億以內(nèi)數(shù)的規(guī)律，使每個學(xué)生都有學(xué)習(xí)成功的體驗，增進(jìn)學(xué)好數(shù)學(xué)的信心。四、教學(xué)內(nèi)容：教科書第2~5頁的內(nèi)容，練習(xí)一的1-5題。五、教學(xué)目標(biāo)：1.使學(xué)生認(rèn)識計數(shù)單位"萬""十萬""百萬""千萬"和"億"，知道億是個大數(shù)；知道億以內(nèi)各計數(shù)單位的名稱和相鄰兩個單位之間的十進(jìn)關(guān)系。2.掌握數(shù)位順序，理解并掌握我國四位一級的計數(shù)習(xí)慣，能夠根據(jù)數(shù)級正確地讀出億以內(nèi)的數(shù)。3.通過情境創(chuàng)設(shè)，小組合作學(xué)習(xí)等形式，使學(xué)生獲得正確讀數(shù)的成功體驗；培養(yǎng)學(xué)生分析、綜合的能力。4.培養(yǎng)學(xué)生對大數(shù)的感受，發(fā)展學(xué)生的數(shù)感。六、教學(xué)重點：億以內(nèi)數(shù)的認(rèn)識，讀法。七、教學(xué)難點：1. 數(shù)級、數(shù)位、計數(shù)單位的區(qū)別以及"位值"的理解。2.每級中間或末尾有0的讀法。八、教具學(xué)具：教師準(zhǔn)備PPT課件，數(shù)位表，師生都備計數(shù)器。

（二）自主探究，學(xué)習(xí)新知。（1）認(rèn)識“11”。讓學(xué)生說說身邊的“11”，接著數(shù)出11根小棒。根據(jù)學(xué)生已有的知識和經(jīng)驗，猜想學(xué)生能順利地數(shù)出；再接著讓學(xué)生另外數(shù)出11根小棒，動手?jǐn)[一擺，探討一下還有沒有別的更好的擺法。比較各種擺法的不同點。[在學(xué)習(xí)新知，突破重難點這一環(huán)節(jié)，讓學(xué)生動口說一說，動手?jǐn)[一擺，用眼觀察，用腦思考，使學(xué)生通過具體實物比較各種擺法，讓學(xué)生借助實物感知10根一捆的原因，建立以一代十的表象認(rèn)知。]（2）學(xué)習(xí)例2中的“15、20”，加深理解組成。讓學(xué)生數(shù)出15根小棒，動手?jǐn)[一擺，捆一捆。引導(dǎo)學(xué)生運(yùn)用上面發(fā)現(xiàn)的容易看出數(shù)量的方法，擺一擺，捆一捆，同桌交流，互相猜猜，根據(jù)實物說出數(shù)量，根據(jù)實物說數(shù)的組成，再倒過來根據(jù)組成說出這個數(shù)。如：“15是由1個十和5個一組成，1個十和5個一組成15?！蓖瑯樱寣W(xué)生動手?jǐn)[擺，捆捆，看看，說說，學(xué)習(xí)“20”。

（四）、課堂小結(jié)：1.提出問題：請談一談這節(jié)課你有哪些收獲?2.你覺得這節(jié)課自己表現(xiàn)怎么樣？誰表現(xiàn)得最好？請你評一評。（進(jìn)一步引導(dǎo)學(xué)生對比較數(shù)的大小的方法進(jìn)行歸納、總結(jié)，從而使學(xué)生完成知識的構(gòu)建。讓學(xué)生對自己和同伴做出評價，以利于學(xué)生今后的成長。）總之，本節(jié)課的設(shè)計力圖體現(xiàn)新課程的理念，以促進(jìn)學(xué)生的發(fā)展為宗旨，充分體現(xiàn)了學(xué)生學(xué)習(xí)的自主性，相信學(xué)生的能力，挖掘?qū)W生的各項能力，，激發(fā)學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣，增強(qiáng)數(shù)學(xué)學(xué)習(xí)的信心，體會數(shù)學(xué)與生活的聯(lián)系。七、說教學(xué)反思在二年級下冊《萬以內(nèi)數(shù)的認(rèn)識》單元中，學(xué)生已經(jīng)掌握了“千以內(nèi)數(shù)的大小比較”的方法，“萬以內(nèi)數(shù)的大小比較”只需在此基礎(chǔ)上完成知識的順遷移即可。因此，在本堂課的教學(xué)設(shè)計中我并不急著把“比較數(shù)的大小”的方法教給學(xué)生，而是把重點放在了學(xué)生對大小比較的真正理解上，通過本節(jié)課的學(xué)習(xí)能用自己的方法解決實際問題。

1、組織理解近似數(shù)的含義。出示例8的主題圖。聰聰去調(diào)查了育英小學(xué)的學(xué)生數(shù)，他寫下了這樣的一句話：“育英小學(xué)有1506人，約是1500人?！庇⑿W(xué)到底有1506人還是1500人呢？為什么？組織學(xué)生進(jìn)行討論、交流。思考：后半句約1500人是什么意思？小組匯報：A、認(rèn)為育英小學(xué)的認(rèn)數(shù)是1506人，因為他告訴我們就是1506人，后半句他說的是約是1500人，是說他們學(xué)校的人數(shù)和1500人的差不多。B、也認(rèn)為育英小學(xué)有1506人，他說約有1500人是大概就是1500人的意思。師小結(jié)：我們把1506這個很準(zhǔn)確的數(shù)字就叫做“準(zhǔn)確數(shù)”，而1500這個和1506差不多的數(shù)就叫做“近似數(shù)”。（邊說邊板書）引導(dǎo)學(xué)生明白近似數(shù)更容易記，因為它正好是正百數(shù)。出示例8主題圖比較一下1506和1500這兩個數(shù)，體會一下準(zhǔn)確數(shù)和近似數(shù)哪個數(shù)更容易記住
人教版新課標(biāo)小學(xué)數(shù)學(xué)二年級下冊萬以內(nèi)數(shù)的認(rèn)識說課稿2篇
【說教學(xué)目標(biāo)】根據(jù)教學(xué)大綱和新課程標(biāo)準(zhǔn)要求，這節(jié)課的教學(xué)目標(biāo)確定為：1、知識與技能：由生活實際出發(fā)，讓學(xué)生感受萬以內(nèi)的數(shù)在生活中的應(yīng)用，進(jìn)一步體會相鄰兩個計數(shù)單位之間的十進(jìn)關(guān)系。學(xué)會讀寫萬以內(nèi)的數(shù)，知道數(shù)的組成，掌握數(shù)位順序表。2、過程與方法：在具體情景中感受大數(shù)的意義，培養(yǎng)學(xué)生的數(shù)感和估計意識；經(jīng)歷觀察、操作及與同伴合作交流等數(shù)學(xué)活動過程，使學(xué)生初步學(xué)會有條理地思考和解決問題。3、情感與態(tài)度：進(jìn)一步體驗數(shù)學(xué)與人類生活的密切聯(lián)系；在活動中體驗學(xué)習(xí)的成功與快樂，培養(yǎng)學(xué)習(xí)數(shù)學(xué)的興趣和自信心并能正確評價自己和他人。其中認(rèn)識數(shù)的計數(shù)單位“萬”，會讀寫萬以內(nèi)的數(shù)，掌握數(shù)位順序表時這節(jié)課的重點，而熟練地讀寫萬以內(nèi)的數(shù)是難點。
