The activity theme of this section is to design various activities around the key words in the first text. Therefore, the activities require students to pay attention to the spelling of words. On the other hand, let students grasp the meaning of words more accurately through sentences and short texts. This kind of teaching design also helps to improve the ability of using English thinking.1. Cultivating students' ability to use word formation to induce and memorize vocabulary, and the ability to use lexical chunks to express meaning.2. Guide the students to think independently and use the correct form of words to complete sentences3. Cultivate students' habit of using lexical chunks to express language completely, guide students to draw words in sentences quickly, pay attention to word collocation, so as to accumulate more authentic expressions4. Instruct students to create sentences with the chunks.1. Enable students to use the language points in the real situation or specific contexts flexibly and appropriately.2. Guiding the Ss to use unit topic words and the sentence patterns in a richer context.Step1: Think of a word that best fits each definition.1. to remember sth2.to accept, admit, or recognize sth or the truth/existence of sth3. the process of changing sth or yourself to suit a new situation4 .to make sb feel less worried or unhappy5. a strong desire to achieve sth
(一)例題引入籃球聯(lián)賽中,每場比賽都要分出勝負(fù),每隊(duì)勝1場得2分,負(fù)1場得1分。某隊(duì)在10場比賽中得到16分,那么這個(gè)隊(duì)勝負(fù)場數(shù)分別是多少?方法一:(利用之前的知識,學(xué)生自己列出并求解)解:設(shè)剩X場,則負(fù)(10-X)場。方程:2X+(10-X)=16方法二:(老師帶領(lǐng)學(xué)生一起列出方程組)解:設(shè)勝X場,負(fù)Y場。根據(jù):勝的場數(shù)+負(fù)的場數(shù)=總場數(shù) 勝場積分+負(fù)場積分=總積分得到:X+Y=10 2X+Y=16
1.直觀圖:表示空間幾何圖形的平面圖形,叫做空間圖形的直觀圖直觀圖往往與立體圖形的真實(shí)形狀不完全相同,直觀圖通常是在平行投影下得到的平面圖形2.給出直觀圖的畫法斜二側(cè)畫法觀察:矩形窗戶在陽光照射下留在地面上的影子是什么形狀?眺望遠(yuǎn)處成塊的農(nóng)田,矩形的農(nóng)田在我們眼里又是什么形狀呢?3. 給出斜二測具體步驟(1)在已知圖形中取互相垂直的X軸Y軸,兩軸相交于O,畫直觀圖時(shí),把他們畫成對應(yīng)的X'軸與Y'軸,兩軸交于O'。且使∠X'O'Y'=45°(或135°)。他們確定的平面表示水平面。(2)已知圖形中平行于X軸或y軸的線段,在直觀圖中分別畫成平行于X'軸或y'軸的線段。(3)已知圖形中平行于X軸的線段,在直觀圖中保持原長度不變,平行于Y軸的線段,在直觀圖中長度為原來一半。4.對斜二測方法進(jìn)行舉例:對于平面多邊形,我們常用斜二測畫法畫出他們的直觀圖。如圖 A'B'C'D'就是利用斜二測畫出的水平放置的正方形ABCD的直觀圖。其中橫向線段A'B'=AB,C'D'=CD;縱向線段A'D'=1/2AD,B'C'=1/2BC;∠D'A'B'=45°,這與我們的直觀觀察是一致的。5.例一:用斜二測畫法畫水平放置的六邊形的直觀圖(1)在六邊形ABCDEF中,取AD所在直線為X軸,對稱軸MN所在直線為Y軸,兩軸交于O',使∠X'oy'=45°(2)以o'為中心,在X'上取A'D'=AD,在y'軸上取M'N'=½MN。以點(diǎn)N為中心,畫B'C'平行于X'軸,并且等于BC;再以M'為中心,畫E'F'平行于X‘軸并且等于EF。 (3)連接A'B',C'D',E'F',F'A',并擦去輔助線x軸y軸,便獲得正六邊形ABCDEF水平放置的直觀圖A'B'C'D'E'F' 6. 平面圖形的斜二測畫法(1)建兩個(gè)坐標(biāo)系,注意斜坐標(biāo)系夾角為45°或135°;(2)與坐標(biāo)軸平行或重合的線段保持平行或重合;(3)水平線段等長,豎直線段減半;(4)整理.簡言之:“橫不變,豎減半,平行、重合不改變?!?/p>
6. 例二:如圖,AB是⊙O的直徑,PA垂直于⊙O所在的平面,C是圓周上的一點(diǎn),且PA=AC,求二面角P-BC-A的大小. 解:由已知PA⊥平面ABC,BC在平面ABC內(nèi)∴PA⊥BC∵AB是⊙O的直徑,且點(diǎn)C在圓周上,∴AC⊥BC又∵PA∩AC=A,PA,AC在平面PAC內(nèi),∴BC⊥平面PAC又PC在平面PAC內(nèi),∴PC⊥BC又∵BC是二面角P-BC-A的棱,∴∠PCA是二面角P-BC-A的平面角由PA=AC知△PAC是等腰直角三角形∴∠PCA=45°,即二面角P-BC-A的大小是45°7.面面垂直定義一般地,兩個(gè)平面相交,如果它們所成的二面角是直二面角,就說這兩個(gè)平面互相垂直,平面α與β垂直,記作α⊥β8. 探究:建筑工人在砌墻時(shí),常用鉛錘來檢測所砌的墻面與地面是否垂直,如果系有鉛錘的細(xì)繩緊貼墻面,工人師傅被認(rèn)為墻面垂直于地面,否則他就認(rèn)為墻面不垂直于地面,這種方法說明了什么道理?
2. 教材分析這節(jié)課的教學(xué)是學(xué)生在掌握行程問題基本數(shù)量關(guān)系的基礎(chǔ)上進(jìn)行的,本課教材給學(xué)生提供了“騎車”的情境,通過簡單的路線圖等方式呈現(xiàn)了速度路程等信息。然后要求學(xué)生根據(jù)這些信息去解決2個(gè)問題:①讓學(xué)生根據(jù)兩輛車的速度信息進(jìn)行估計(jì),在哪個(gè)地方相遇。②用方程解決相遇問題中求相遇時(shí)間的問題。3. 學(xué)情分析學(xué)生已經(jīng)在三年級接觸了簡單的行程問題,四年級上冊,學(xué)生就真正的開始學(xué)習(xí)速度、時(shí)間、路程之間的關(guān)系,并用三者的數(shù)量關(guān)系來解決行程問題。而本節(jié)課正是運(yùn)用這些學(xué)生已有的知識基礎(chǔ)和生活經(jīng)驗(yàn)進(jìn)行相遇問題的探究。4、教學(xué)目標(biāo)從知識與技能、過程與方法、情感態(tài)度價(jià)值觀的三維目標(biāo)出發(fā),制定了以下的目標(biāo):①使學(xué)生理解相遇問題的意義及特點(diǎn)。②經(jīng)歷解決問題的過程,提高收集信息、處理信息和建立模型的能力。③會分析簡單實(shí)際問題中的數(shù)量關(guān)系,提高用方程解決簡單的實(shí)際問題的能力。
活動內(nèi)容:教師首先讓學(xué)生回顧學(xué)過的三類事件,接著讓學(xué)生拋擲一枚均勻的硬幣,硬幣落下后,會出現(xiàn)正面朝上、正面朝下兩種情況,你認(rèn)為正面朝上和正面朝下的可能性相同嗎?(讓學(xué)生體驗(yàn)數(shù)學(xué)來源于生活)?;顒幽康模菏箤W(xué)生回顧學(xué)過的三類事件,并由擲硬幣游戲培養(yǎng)學(xué)生猜測游戲結(jié)果的能力,并從中初步體會猜測事件可能性。讓學(xué)生體會猜測結(jié)果,這是很重要的一步,我們所學(xué)到的很多知識,都是先猜測,再經(jīng)過多次的試驗(yàn)得出來的。而且由此引出猜測是需通過大量的實(shí)驗(yàn)來驗(yàn)證。這就是我們本節(jié)課要來研究的問題(自然引出課題)。
教學(xué)目標(biāo)1、明確扇形統(tǒng)計(jì)圖的制作步驟,能夠根據(jù)相關(guān)數(shù)據(jù)較為準(zhǔn)確地制作扇形統(tǒng)計(jì)圖.2、進(jìn)一步理解扇形統(tǒng)計(jì)圖的特點(diǎn),建立百分比大小和扇形圓心角大小之間初步的直觀敏感度.3、能夠?qū)崿F(xiàn)不同統(tǒng)計(jì)圖數(shù)據(jù)間的合理轉(zhuǎn)換,再次體會幾種統(tǒng)計(jì)圖的不同特點(diǎn),為合理選擇統(tǒng)計(jì)圖表示數(shù)據(jù)打下一定的基礎(chǔ).4、通過實(shí)例,理解三種統(tǒng)計(jì)圖的特點(diǎn),能根據(jù)具體問題選擇合適的統(tǒng)計(jì)圖清晰、有效地描述數(shù)據(jù).5、在統(tǒng)計(jì)活動的過程中,通過相互間的合作與交流,掌握畫統(tǒng)計(jì)圖和選擇統(tǒng)計(jì)圖的方法;經(jīng)歷數(shù)據(jù)的收集、整理和簡單分析、作出決策的統(tǒng)計(jì)活動過程,發(fā)展統(tǒng)計(jì)觀念.6、通過對現(xiàn)實(shí)生活中的數(shù)據(jù)分析,感受數(shù)學(xué)與現(xiàn)實(shí)生活的密切聯(lián)系,說出統(tǒng)計(jì)圖在現(xiàn)實(shí)生活中的應(yīng)用,提高學(xué)習(xí)數(shù)學(xué)興趣.
小學(xué)五年級的學(xué)生應(yīng)該具備一些生活技能, 學(xué)做家常菜是我們生活的必需,是每個(gè),人都應(yīng)該掌握的生存技能。本主題的目的通過學(xué)習(xí)做簡單的家常菜,引領(lǐng)小學(xué)生走進(jìn)家務(wù)勞動,鍛煉生活的自理能力和提高適應(yīng)生活的能力,體會生活和學(xué)習(xí)的樂趣,激發(fā)學(xué)生將學(xué)校學(xué)習(xí)和家務(wù)勞動密切結(jié)合起來,形成積極的生活和學(xué)習(xí)的態(tài)度。本主題安排了“問題與思考”“學(xué)習(xí)與探究”“實(shí)踐與體驗(yàn)”總結(jié)與交流“拓展與創(chuàng)新”五個(gè)環(huán)節(jié),從提出問題開始,到探究與體驗(yàn),最后到學(xué)有所用,循序漸進(jìn),引導(dǎo)學(xué)習(xí)走進(jìn)中式餐飲文化,學(xué)做日常生活中的家常菜,掌握勞動的技能和方法,體驗(yàn)做家務(wù)勞動帶來的快樂和享受,激發(fā)學(xué)生對家常菜的探究與實(shí)踐的興趣,逐步掌握日常生活所需的基本技能,培養(yǎng)熱愛勞動、熱愛生活的意識。
四個(gè)同學(xué)為一個(gè)合作小組;每個(gè)小組利用教師為其準(zhǔn)備的各類三角形,作出它們的高.比一比,看哪一個(gè)小組做得最快,發(fā)現(xiàn)的結(jié)論多. 師生行為:學(xué)生操作、討論,教師巡視、指導(dǎo),使學(xué)生理解【設(shè)計(jì)意圖】通過讓學(xué)生操作、觀察、推理、交流等活動,來培養(yǎng)學(xué)生的動手、動腦能力,發(fā)展其空間觀察.活動結(jié)論:1.銳角三角形的三條高都在三角形內(nèi); 2.直角三角形的一條高在三角形內(nèi)(即斜邊上的高),而另兩條高恰是它的兩條直角邊; 3.鈍角三角形的一條高在三角形內(nèi),而另兩條高在三角形外.(這是難點(diǎn),需多加說明) 總之:任何三角形都有三條高,且三條高所在的直線相交于一點(diǎn).(我們把這一點(diǎn)叫垂心)課堂小結(jié) 1.三角形中三條重要線段:三角形的高、中線和角平分線的概念. 2.學(xué)會畫三角形的高、中線和角平分線.
(一)、創(chuàng)設(shè)情景,導(dǎo)入新課摸牌游戲:三位同學(xué)持三組牌,指定三位同學(xué)分別任意摸出一張,看誰能摸到紅牌,他們一定能摸到紅牌嗎?請手持牌的同學(xué)根據(jù)自已手中牌的情況,用語言描述一下抽出紅牌的情況??偨Y(jié):在一定條件下,有些事情我們事先能肯定它一定發(fā)生,這些事情成為 事件。有些事情我們事先能肯定它一定不會發(fā)生,這些事情稱為 事件。 事件和 事件統(tǒng)稱為確定事件。許多事情我們事先無法肯定它會不會發(fā)生,這些事情稱為 事件,也稱為 事件。
我們不妨將主旨放在“莊生曉夢迷蝴蝶,望帝春心托杜鵑。滄海月明珠有淚,藍(lán)田日暖玉生煙?!倍?lián)之前,那么,事情就變得簡單起來了:華年如莊生曉夢迷蝴蝶;華年如望帝春心托杜鵑;華年如滄海月明珠有淚;華年如藍(lán)田日暖玉生煙。從課下注釋,我們很容易就可以看出,這四句每一句都在用典。因此,我們通過對典故的解讀,然后加以整理,將其理順,似乎就可以完成對詩歌內(nèi)容的解讀;至于什么悼亡、愛情,不妨拋之腦后,畢竟,沒有那些其他的主題,也并沒有讓詩歌失色,而加上這些捉摸不定的主題,只是讓詩歌增加了所謂的神秘色彩,徒增閱讀難度而已。
教師活動 學(xué)生活動設(shè)計(jì)意圖 情境導(dǎo)入:教師配樂敘述詩歌創(chuàng)作背景投入傾聽 盡可能調(diào)動學(xué)生情緒誦讀入境:“讀李詩者于雄快之中得其深遠(yuǎn)宕逸之神,才是謫仙人面目”(投影展示)教師范讀,醞釀情感(播放配樂)1、學(xué)生自讀感知詩韻 2、學(xué)生齊讀進(jìn)入詩境 調(diào)動學(xué)生積極性,誦讀時(shí)用自己的情緒感染學(xué)生精讀涵詠:教師就詩歌內(nèi)容進(jìn)行提問,李白怎樣喝酒,勸朋友喝酒的方式、原因,他有那些愁并說明理由,并按照自己的理解誦讀。教師必要時(shí)給出相應(yīng)的提示。投影展示:人生苦短 懷才不遇 交流研討誦讀 引導(dǎo)學(xué)生從詩句入手,疏通詩意,把握情感
(一)知識與能力 1、指導(dǎo)學(xué)生基本掌握誦讀本詩的要領(lǐng),培養(yǎng)學(xué)生聲情并茂、準(zhǔn)確傳達(dá)情感的誦讀能力. 2、幫助學(xué)生初步了解“初讀—精讀—悟讀—美讀”的詩歌鑒賞方法,培養(yǎng)學(xué)生鑒賞古典詩歌的能力。(二)、情感態(tài)度與價(jià)值觀 1、走近李白的激情、浪漫、詩性和放達(dá),感受全詩恢宏的氣魄。 2、激發(fā)學(xué)生與文本、文人和文化的親近之情
《錦瑟》的主旨頗多,悼亡、戀情、自傷身世,每一種都有其支持者的長篇論述,但其首聯(lián)中“一弦一柱思華年。”從這個(gè)角度來看,似乎將主題定調(diào)為對“華年”的追思,似乎更為妥帖。當(dāng)我們有了一個(gè)明確的基調(diào)之后,后面幾聯(lián)在解讀時(shí)就有了一個(gè)準(zhǔn)確的方向。
