教學內容:整數乘法運算定律推廣到小數乘法 (P.12頁例8和“做一做”,練習二第2題。)教學要求: 使學生理解整數乘法的運算定律對于小數同樣適用,并會運用乘法的運算定律進行一些小數的簡便計算。教學重點: 乘法運算定律中數(包括整數和小數)的適用范圍。教學難點: 運用乘法的運算定律進行小數乘法的的簡便運算。教學用具:投影片若干張。教學過程:一、激發(fā):1、計算:25×95×4 25×32 4×48+6×48 102×562、在整數乘法中我們已學過哪些運算定律?請用字母表示出來。根據學生的回答,板書:乘法交換律 ab=ba乘法結合律 a(bc)=(ab)c乘法分配律 a(b+c)=ab+ac2、讓學生舉例說明怎樣應用這些定律使計算簡便。(注意學生舉例時所用的數。)3、出示教材P.9頁的3組算式:下面每組算式左右兩邊的結果相等嗎?

【教學過程】一、從實際情景入手,引入新知,使學生學會在具體情景中用數對確定位置1.談話引入。今天有這么多老師和我們一起上課,同學們歡迎嗎?老師們都很想認識你們。咱們先來給他們介紹一下我們班的班長,可以嗎?2.合作交流,在已有經驗的基礎上探究新知。(1)出示要求:以小組為單位,想一想,可以用什么方法表示出班長的位置,把你的方法寫或畫在紙上。匯報:班長的位置在第4組的第三個,他在從右邊數第二組的第三排…哪個小組也用語言描述出了班長的位置?請班長起立,他們的描述準確嗎?剛才同學們的描述有什么相同和不同?(都表示的是班長的位置,有的同學說第幾組,第幾行,第幾排……)看來在日常生活中,我們可以用組、排、行、等多種方式,還可以從不同的方位來描述物體的位置。為了我們在確定位置的時候語言達成一致,一般規(guī)定:豎排叫列,橫排叫行。
《貼郵票》活動要求:A、每組4人,給四封不同地點、質量的信件B、根據信封上的信息計算郵費并按要求貼上郵票(郵票的總面值剛好等于郵費,不能多貼)每封信最多貼三張郵票,只有0.8元或1.2元的兩種郵票紀律要求:看看哪組合作得最好,速度最快!如果遇到困難,在事發(fā)那個在一邊最后再去解決。3、小組匯報(1)、貼郵票的過程中大家遇到了什么問題?(有的能貼有的不能貼)這樣的信件有哪些?(告訴我地點、質量、郵費)(2)、其他的信件都能貼出來嘛?說說看你是怎么貼郵票的?(3)、請將你們貼好郵票的信件送到郵箱來。剩下的都是一些“難題”(4)、思考:為什么4.0元、4.8元、6元的郵費沒有辦法按要求貼出郵票?(5)、原因出在哪里?這個問題怎么解決?(郵票面值太小,將郵票的面值改大)(6)、那最少要改成多大的?為什么?(將郵票面值改大,你會從多大面值的郵票開始考慮?為什么?)
(3)確立按生產要素分配的意義確立按生產要素分配的原則,是對市場經濟條件下各種生產要素所有權存在的合理性、合法性的確認,體現了國家對公民權利的尊重,對勞動、知識、人才、創(chuàng)造的尊重。有利于讓一切生產要素的活力競相迸發(fā),讓一切創(chuàng)造社會財富的源泉充分涌流,以造福人民。(三)課堂總結、點評 通過這節(jié)課的學習,我們懂得了在我國社會主義初級階段,實行以按勞分配為主體、多種分配方式并存的制度,把按勞分配和按生產要素分配結合起來具有客觀必然性,也有重要的意義?!镎n余作業(yè) 組織學生撰寫社會調查報告,要求學生調查自己家里的收入情況,分清哪些收入是按勞分配所得,哪些是非按勞分配收入,并進一步分析現在的收入形式與以前相比有哪些變化,這種變化給家庭的生活帶來哪些影響?★教學體會本節(jié)內容是與學生生活實際密切聯(lián)系的內容,在學習中應該多引入日常生產、生活中常見的一些實例,讓學生去深刻理解這些知識,并能夠從自己的實踐中理解、把握我國分配政策的合理性。

一、知識和能力目標本單元的核心教學內容是“認物”。用英語確認周圍的常見事物比較符合英語初學者的實際情況。通過本單元教學,使學生運用所學句型,去熟悉周圍事物的名稱;教學生學會在實際生活中如何確認事物。通過辨認物體,學生學到一些生詞,并鞏固所學句型。二、過程和方法目標教師要盡量使學生對課文中出現的句型能夠熟練上口,這樣,學生才能順利開展比較靈活的對話。教師可以用手勢,表情,動作等示意,幫助學生聽懂課堂教學內容,但在實際操作中應盡量避免“明知故問”的傾向,應該采用應用性原則;如:遮蓋物品、顯露局部、辨認物體、完形識別、圖形辨認等方法。三、情感態(tài)度和價值觀目標目標在學生學習過程中的作用至關重要,教師要幫助他們建立起一個切合自己實際的目標,通過漸進的學習以及一點一滴的進步,使他們逐步建立起成功感。成功越多,自信心就越強。

“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”.
