    人教版新課標(biāo)小學(xué)數(shù)學(xué)五年級下冊3的倍數(shù)的特征說課稿

    一、教材分析《3的倍數(shù)的特征》是人教版實驗教材小學(xué)數(shù)學(xué)五年級下冊第19頁的內(nèi)容,它是在因數(shù)和倍數(shù)的基礎(chǔ)上進(jìn)行教學(xué)的,是求最大公因數(shù)、最小公倍數(shù)的重要基礎(chǔ),也是學(xué)習(xí)約分和通分的必要前提。因此,使學(xué)生熟練地掌握2、5、3的倍數(shù)的特征,具有十分重要的意義。教材的安排是先教學(xué)2、5的倍數(shù)的特征,再教學(xué)3的倍數(shù)的特征。因為2、5的倍數(shù)的特征僅僅體現(xiàn)在個位上的數(shù),比較明顯,容易理解。而3的倍數(shù)的特征,不能只從個位上的數(shù)來判定,必須把其各位上的數(shù)相加,看所得的和是否是3的倍數(shù)來判定,學(xué)生理解起來有一定的困難,因此,本課的教學(xué)目標(biāo),我從知識、能力、情感三方面綜合考慮,確定教學(xué)目標(biāo)如下:1、使學(xué)生通過理解和掌握3的倍數(shù)的特征,并且能熟練地去判斷一個數(shù)是否是3的倍數(shù),以培養(yǎng)學(xué)生觀察、分析、動手操作及概括問題的能力,進(jìn)一步發(fā)展學(xué)生的數(shù)感。

    (4)判斷中進(jìn)行教學(xué)內(nèi)容的遞深,形成了反思——學(xué)習(xí)——強(qiáng)化的整個學(xué)習(xí)過程。在學(xué)生做出“6是倍數(shù)”的正確判斷之后,并不簡單換章,而是以此為契機(jī)“教學(xué)找一個數(shù)的因數(shù)”以談話導(dǎo)入,形成知識相互的聯(lián)系與區(qū)別,“談話:必須說清誰是誰的倍數(shù),誰是誰的因數(shù)。所以6可能是某些數(shù)的倍數(shù),也可能是某些數(shù)的因數(shù),那我們就來找一個數(shù)的因數(shù)。你能找出36所有的因數(shù)嗎?”(5)討論互評,自主學(xué)習(xí)放手讓學(xué)生學(xué)習(xí)找一個數(shù)的因數(shù),從無序到有序,從自尋到互學(xué),請學(xué)生板書,學(xué)生評價,“提問:你是用什么方法找到一個數(shù)的因數(shù),可以介紹給大家嗎?還有其他方法嗎?”1×36=36 36÷1=362×18=36 36÷2=183×12=36 36÷3=124×9=363 6÷4=96×6=36 36÷6=6(6)自主不失指導(dǎo),掌握不失總結(jié)如:提問:5為什么不是36的因數(shù)?(因為36÷5不能整除,有余數(shù))

    1、同學(xué)們,老師這里收到了一位法國大作家雨果的來信,讓我一起來聽一聽?!霸谑澜绲囊挥?,存在著人類的一大奇跡,這個奇跡就是圓明園。圓明園屬于幻想藝術(shù)。一個近乎超人的民族所能幻想到的一切都薈集于圓明園。只要想象出一種無法描繪的建筑物,一種如同月宮似的仙境,那就是圓明園。假定有一座集人類想象力之大成的寶島,以宮殿廟宇的形象出現(xiàn),那就是圓明園?!?、聽了雨果的這段話,你腦海中的圓明園是怎么樣的?有什么疑問嗎?3、但是,這一奇跡現(xiàn)在已蕩然無存,留在我們眼前的只有幾根殘缺的大石柱。它們靜靜地站在那里,像一座紀(jì)念碑,訴說那段屈辱的歷史—板書:圓明園的訴說。二、學(xué)習(xí)新課,體驗明理活動一:驚嘆圓明園的輝煌師:圓明園是一座皇家園林,現(xiàn)在卻只留下這些殘垣斷壁。那么,你知道圓明園在哪兒嗎?你知道多少關(guān)于圓明園的故事?

    (二)理性面對:交流方式多。1、其實,遇到問題并不可怕,辦法總比困難多。2.閱讀王玉理的故事,你受到哪些啟發(fā)?3.交流方式有很多:如寫信、留言條等。4.情景出示:班里很多學(xué)生都可以用鋼筆書寫了,由于我寫字漏字錯字現(xiàn)象多,老師讓我再練練,可是媽媽覺得是我寫字寫得不好。我認(rèn)為這明明是兩個問題,媽媽的誤解讓我很不開心。如果是你,你會怎么做呢?選擇合適的方式,試著主動和媽媽交流溝通吧。(三)我愛家人:發(fā)現(xiàn)父母的美。1、小組內(nèi)合作,閱讀課前小調(diào)查“我眼中的父母別人眼中的父母”,說說有什么新的發(fā)同伴身上學(xué)現(xiàn)?2.列舉事例說說父母身上的父母的閃光點,交流自己的感受。3.教師總結(jié)。(四)拓展延伸:布置活動作業(yè)。1.布置課后活動作業(yè)。2.小結(jié):明確下節(jié)課學(xué)習(xí)內(nèi)容。
