1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語中表達(dá)做某事的步驟的一種說法。如果步驟較多,還可以說:first-next-after that-later on-finally/at last通常你會(huì)聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時(shí),他們會(huì)做一些停頓。這樣就能提前告訴聽者接下來講的是一系列的步驟。這一點(diǎn)在朗讀和聽力中應(yīng)特別注意。2. how many, how much均為疑問詞,同是“多少”,但用法不同。請(qǐng)看:how many修飾可數(shù)名詞復(fù)數(shù),how much修飾不可數(shù)名詞。但在用法上,同學(xué)們常犯如下錯(cuò)誤:1) [誤] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容詞,常修飾名詞作定語,故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時(shí),謂語動(dòng)詞用單數(shù)。how many與how much的區(qū)別可簡(jiǎn)記為:前how many:?jiǎn)枴岸嗌佟?,?fù)數(shù)名詞后面跑;how much問“多少”,不可數(shù)名詞單數(shù)好。前者答語用基數(shù)詞,后者答語用數(shù)量關(guān)系。

一、說教材分析 《除數(shù)是整數(shù)的小數(shù)除法》是九年制義務(wù)教育第二學(xué)段數(shù)與代數(shù)領(lǐng)域的內(nèi)容,是在學(xué)生已經(jīng)掌握了整數(shù)除法的意義和計(jì)算方法,小數(shù)的意義和性質(zhì)等基礎(chǔ)上進(jìn)行學(xué)習(xí)的。本節(jié)課也是整數(shù)除法意義上的進(jìn)一步擴(kuò)展,也將為今后學(xué)習(xí)小數(shù)除以小數(shù)、小數(shù)四則混合運(yùn)算打下基礎(chǔ)。因此,學(xué)生掌握本節(jié)課的內(nèi)容有重要的意義和作用。 二、說學(xué)情分析學(xué)生已掌握整數(shù)除法、小數(shù)的意義和基本性質(zhì)以及小數(shù)乘法等知識(shí),應(yīng)充分利用學(xué)生的生活經(jīng)驗(yàn)和已有知識(shí),引導(dǎo)學(xué)生探索除數(shù)是整數(shù)的小數(shù)除法的計(jì)算方法。 根據(jù)教材內(nèi)容,結(jié)合學(xué)生的心理特征和認(rèn)知結(jié)構(gòu),制定教學(xué)目標(biāo)如下: 1、知識(shí)與技能:使學(xué)生理解算理;掌握算法并能正確地進(jìn)行計(jì)算。 2、過程與方法:在探究算法的過程中,培養(yǎng)學(xué)生的類推能力、分析能力和抽象概括能力。 3、情感態(tài)度和價(jià)值觀:使學(xué)生體驗(yàn)所學(xué)知識(shí)與現(xiàn)實(shí)生活的聯(lián)系,能解決生活中簡(jiǎn)單問題。

一、說教材今天我說課的課題是《一個(gè)數(shù)乘小數(shù)》。它是人教版小學(xué)五年級(jí)上冊(cè)第一單元第二課時(shí)的教學(xué)內(nèi)容。本課時(shí)內(nèi)容是在學(xué)生學(xué)習(xí)了小數(shù)點(diǎn)位置移動(dòng)引起小數(shù)大小變化的規(guī)律,以及前一節(jié)課《小數(shù)乘整數(shù)》的基礎(chǔ)上進(jìn)行教學(xué)的,它既是小數(shù)除法學(xué)習(xí)的基礎(chǔ),也是小數(shù)四則混合運(yùn)算學(xué)習(xí)的基礎(chǔ)。本節(jié)課的教學(xué)目標(biāo)為:1、讓學(xué)生進(jìn)一步鞏固掌握一個(gè)數(shù)乘小數(shù)的意義和計(jì)算方法,通過學(xué)生的積極思考、全班交流和教師引導(dǎo),得出確定積的小數(shù)位數(shù)時(shí),位數(shù)不夠要用“0”補(bǔ)足的方法。并能正確進(jìn)行筆算和口算。2、讓學(xué)生體驗(yàn)學(xué)習(xí)過程是一個(gè)不斷遇到問題、不斷探究解決問題方法的過程,感受探索成功的愉悅,感受數(shù)學(xué)與生活的聯(lián)系。3、在探索過程中,培養(yǎng)學(xué)生的推理能力、歸納能力和語言表達(dá)能力。

一、說教材《一個(gè)數(shù)除以小數(shù)》是人教版數(shù)學(xué)五年級(jí)上冊(cè)第三單元的第二個(gè)內(nèi)容。小數(shù)除法是繼整數(shù)除法、分?jǐn)?shù)除法之后數(shù)的除法的又一次擴(kuò)展,分為一個(gè)數(shù)除以整數(shù)和一個(gè)數(shù)除以小數(shù)兩種情況?!俺龜?shù)是小數(shù)的除法”是小學(xué)數(shù)學(xué)教學(xué)中的一個(gè)重點(diǎn),又是難點(diǎn),它在計(jì)算教學(xué)中處于關(guān)鍵地位。它是綜合性最強(qiáng)的計(jì)算,包含了商不變的性質(zhì)、小數(shù)的基本性質(zhì)、試商的方法,還有商中間有零的除法、商末尾有零的除法,為以后的小數(shù)四則運(yùn)算的學(xué)習(xí)打下堅(jiān)實(shí)的基礎(chǔ)。教材通過設(shè)置生活情境,引出問題,學(xué)生產(chǎn)生認(rèn)知沖突,激發(fā)學(xué)習(xí)興趣。教材在編排時(shí)重點(diǎn)突出運(yùn)用商不變性質(zhì)把除數(shù)是小數(shù)的除法轉(zhuǎn)化成除數(shù)是整數(shù)的除法,將新知轉(zhuǎn)化為舊知。本節(jié)課的教學(xué)重點(diǎn)是讓學(xué)生理解并掌握一個(gè)數(shù)除以小數(shù)的算理和計(jì)算方法。教學(xué)難點(diǎn)是讓學(xué)生理解“被除數(shù)的小數(shù)點(diǎn)位置的移動(dòng)要隨著除數(shù)的變化而變化”。

一、教材及學(xué)情分析“數(shù)學(xué)廣角”是新教材在向?qū)W生滲透數(shù)學(xué)思想方面做出的新嘗試。本課內(nèi)容重在向?qū)W生滲透簡(jiǎn)單的排列組合的數(shù)學(xué)思想方法,并初步培養(yǎng)學(xué)生有順序地、全面地思考問題的意識(shí)。本課內(nèi)容是學(xué)生在小學(xué)階段初次接觸有關(guān)排列組合的知識(shí),但是在日常生活中,有很多事情是用排列組合來解決的,如:衣服的搭配、付錢時(shí)面值的選擇等等。二、學(xué)習(xí)目標(biāo)及教學(xué)重、難點(diǎn)通過對(duì)本教材的深入研究,結(jié)合新課程的三維目標(biāo)理念,我確定了如下的學(xué)習(xí)目標(biāo):1.通過觀察、猜測(cè)、操作等活動(dòng),找出簡(jiǎn)單事物的排列數(shù)與組合數(shù)。2.經(jīng)歷探索簡(jiǎn)單事物排列與組合規(guī)律的過程,掌握有序地全面思考問題的方法。三、教法、學(xué)法設(shè)計(jì)根據(jù)本課教學(xué)內(nèi)容的特點(diǎn)和學(xué)生的思維特點(diǎn),我采用情境教學(xué)法、操作發(fā)現(xiàn)法、直觀演示法。為使學(xué)生能夠有效地學(xué)習(xí),主動(dòng)的建構(gòu)知識(shí)。我采用合作交流法、動(dòng)手操作法、自主探究的學(xué)習(xí)方法,讓學(xué)生在一系列活動(dòng)中感知有順序的搭配。

1.說課內(nèi)容本課時(shí)的內(nèi)容是九年義務(wù)教育人教版小學(xué)數(shù)學(xué)二年級(jí)上冊(cè)第四單元表內(nèi)乘法(一)的內(nèi)容。2.教材地位及作用“5的乘法口訣”這部分內(nèi)容是在學(xué)生已經(jīng)掌握乘法意義的基礎(chǔ)上進(jìn)行教學(xué)的,是學(xué)習(xí)編寫口訣的開端,其地位尤為重要;由于學(xué)生有五個(gè)五個(gè)數(shù)數(shù)的基礎(chǔ)和經(jīng)驗(yàn),很容易得出2個(gè)5,3個(gè)5,4個(gè)5,5個(gè)5的和。再聯(lián)系乘法的意義,從加法算式到乘法算式,最后編寫乘法口訣;使學(xué)生在理解的基礎(chǔ)上掌握5的乘法口訣。二、說教學(xué)目標(biāo):知識(shí)目標(biāo):知道5的乘法口訣的來源,理解每句口訣的含義,并能熟記5的乘法口訣。能力目標(biāo):學(xué)生能夠靈活運(yùn)用5的乘法口訣解決簡(jiǎn)單的實(shí)際問題,初步培養(yǎng)學(xué)生觀察、分析、歸納的能力。情感目標(biāo):讓學(xué)生體會(huì)數(shù)學(xué)與生活的密切聯(lián)系,激發(fā)學(xué)生熱愛數(shù)學(xué)的情感。
