二年級數(shù)學下冊第二單元表內(nèi)除法教案
一、教材簡析 本單元教學內(nèi)容主要有：除法的初步認識、用2～6的 乘法口訣求商，解決實際問題。除法的初步認識分兩個層次：第一，以生活中常見的“每份同樣多”的實例合活動情境，讓學生建立“平均分”概念。第二，在“平均分”概念的基礎上引出除法運算，說明除法算式各部分的名稱。用口訣求商遵循由易到難的原則。解決問題是結合除法計算出現(xiàn)的。首先在除法的初步認識教學中 孕伏解決問題的內(nèi)容。然后在用2～6的乘法口訣求商之后編入了解決有關平均分的實際問題和需要用乘法和除法兩步計算解決簡單實際問題的內(nèi)容。

小學數(shù)學人教版一年級上冊《0的認識》說課稿第二課時
尊敬的各位老師：大家好！我說課的內(nèi)容是九年義務教育教科書［人教版］一年級數(shù)學上冊三單元第七節(jié)《0的認識》。下面我從教材、學生、教法、學法、教學過程、板書、課后反思等幾個方面談談對本節(jié)課的理解和設計。 一、說教材 1、教材簡析： 日常生活中經(jīng)常使用0，在不同場合，0往往有不同的意思。對此，教材有明確的要求。 （1）、著重教學“一個也沒有，可以用0表示”。讓學生在情景中體會0也是一個數(shù)，它的產(chǎn)生也是計數(shù)的需要。 （2）、結合直尺教學0，0還可以表示起點。 （3）、讓學生體會0在生活中的廣泛應用。 教材通過猴子吃桃的有趣情境引入，使學生直觀體會到什么都沒有可以用“0”來表示。接著利用直尺認識“0”還可以表示起點，并使學生進一步熟悉了數(shù)的順序。在學習了“0”的書寫后，利用小鳥等動物活動圖學習有關“0”的加減法，使學生感受生活中的數(shù)學，快樂學習。 2、學習目標： 這節(jié)課我和學生要達到的學習目標是： （1）、通過觀察感知,讓學生知道0可以表示“沒有”，還可以表示“起點”，并且會給數(shù)排列順序。
小學數(shù)學人教版一年級上冊《8和9的認識》說課稿第二課時
一、教材分析義務教育課程標準實驗教科書數(shù)學（人教版）一年級上冊第五單元，把8和9的認識放在同一節(jié)課中完成，編排與前面6和7的認識基本上一樣，只是要求更高。教材中提供給學生數(shù)數(shù)的資源雖不如6和7明顯，卻更豐富。提供給學生數(shù)數(shù)的對象是以“熱愛自然，保護環(huán)境”為主題的生動畫面，其內(nèi)容有人、花、樹、花盆、蝴蝶、黑板上的字等。畫面除數(shù)數(shù)外，還體現(xiàn)了環(huán)保教育的主題。8和9的序數(shù)意義仍是采取6和7的編排方法，不同的是讓學生更具體地感受幾和第幾的意義的不同?；谝陨戏治?，確定了以下教學目標：1．體會8和9的基數(shù)的含義。 2．了解8和9在自然數(shù)中的排列順序，會比較0～9各數(shù)的大小，知道8和9的序數(shù)含義。 3．培養(yǎng)學生初步的收集信息、處理信息的能力。 4．結合8和9的學習，向?qū)W生滲透環(huán)保教育和勞動教育。 教學重點、難點：學會比較0—9各數(shù)的大小。
小學數(shù)學人教版一年級上冊《10的認識》說課稿第二課時
一、說教材1、教材內(nèi)容分析：本課是人教版1年級數(shù)學上冊第五單元的內(nèi)容。10的認識的編排與前面8、9的認識基本相同，先顯示一幅主題圖供學生數(shù)數(shù)抽象出數(shù)10，再認識10、10以內(nèi)數(shù)的順序，比較相鄰兩個數(shù)的大小，最后學習10的組成和寫數(shù)。10的組成十分重要，它是今后學習20以內(nèi)進位加法和進一步認識100以內(nèi)、萬以內(nèi)以及多位數(shù)的基礎。 2、教學目標： （1）引導學生經(jīng)歷認識10的過程，初步建立10的數(shù)感。 （2）學會10的數(shù)數(shù)、認數(shù)、讀數(shù)、寫數(shù)、比較大小和組成，對10的數(shù)概念獲得全面認識和掌握。 （3）引導學生感受數(shù)10與實際生活的密切聯(lián)系，培養(yǎng)熱愛祖國、熱愛集體的情感。 3、教學重點： 掌握10的數(shù)概念和10的組成，體驗數(shù)學在身邊。 4、教學難點： 熟練掌握10的組成。 5、教具、學具準備： 多媒體課件、學具袋

（一）觀圖激趣、設疑導入 師:上一節(jié)我們已經(jīng)認識了比例,知道兩個比怎樣才能組成比例,下面請同學們判斷一下下面各組的比能否組成比例。(1)0.4∶和1.2∶2 (2)和生1:根據(jù)比例的意義,第(1)題,這兩個比的比值相等,都是0.6,所以(1)題的兩個比能組成比例。生2:我來回答第(2)題,我也利用比例的意義,求出=5,=6,這兩個比的比值不相等,所以第(2)題的兩個比不能組成比例。師:這兩名同學回答的真好,有理有據(jù),讓我們?yōu)樗麄兊谋憩F(xiàn)鼓掌!師:今天這節(jié)課,我們將共同來學習用另一種方法來判斷兩個比能否組成比例,同學們想知道是什么方法嗎?生:想知道。師:那就是比例的基本性質(zhì)(板書課題:比例的基本性質(zhì))?！驹O計意圖】復習學生已有的知識,喚醒學生已有學習經(jīng)驗,教師的提問吸引了學生的注意力,也引發(fā)學生的好奇心,為學習新知識開了一個好頭。
小學數(shù)學人教版六年級下冊《第二課成反比例的量》教案說課稿
【教學過程】（一）觀圖激趣、設疑導入 出示課件的第一張幻燈片。1、成正比例的量有什么特征?2、正比例關系式。生1：兩種相關聯(lián)的量,一種量變化,另一種量也隨著變化。生2：兩種量中相對應的兩個量的比值（商）一定。生3：=k(一定)。師:同學們非常棒！我們今天繼續(xù)學習兩種量的另外一種關系。 (板書:成反比例的量)【設計意圖】這種方法的導入，簡簡單單的一道練習題,把學生的注意力吸引到本節(jié)主要內(nèi)容上來,激起學生的好奇心,真的還有另外一種關系!我可得好好聽一聽。這樣在學習反比例時學生會始終保持高度的精神集中,有利于教師教學順利進行。（二）探究新知教學例2,探究反比例的意義,理解成反比例的量。1、出示PPT課件回答問題。杯子的底面積與水的高度的變化情況如下表。 杯子的底面積/cm²1015203060…水的高度/cm302015105…觀察上表,回答下面的問題。（1）表中有哪兩種量?（2）水的高度是怎樣隨著杯子底面積的大小變化而變化的?（3）相對應的杯子的底面積與水的高度的乘積分別是多少?生1:表中有杯子的底面積和水的高度這兩種量。生2:從表中可以看出:水的高度隨著杯子的底面積的變大而不斷變小,這兩種量是相關聯(lián)的兩種量。生3:我來回答(3),相對應的杯子的底面積與水的高度的乘積分別是:10×30=15×20=20×15=30×10=60×5=…=300。生4:乘積一定。師:底面積與高的乘積表示的是什么?生:水的體積。(板書)師：你會算出水的體積嗎？生：會。（學生計算，教師出示課件訂正）2、揭示反比例的意義。師:積是300,實際就是倒入杯子的水的體積。同學們能用式子表示出它們的關系嗎?生:它們的關系是:底面積×高=體積。師:同學們,我們用概括正比例意義時的方法來概括一下反比例的意義吧!生:像這樣,兩種相關聯(lián)的量,一種量變化,另一種量也隨著變化,如果這兩種量中相對應的兩個數(shù)的乘積一定,這兩種量就叫做成反比例的量,它們的關系叫做反比例關系。(板書反比例的意義)3、用字母表示反比例關系:xy=k(一定)。(板書)4、牛刀小試。鍋爐房燒煤的天數(shù)與每天燒煤的噸數(shù)如下表: 每天燒煤的噸數(shù)/噸11.522.53燒煤的天數(shù)/天3020151210(1)表中有哪兩種量?它們是不是相關聯(lián)的量?(2)寫出幾組這兩種量中相對應的兩個數(shù)的積,并比較大小,說一說這個積表示什么。(3)燒煤的天數(shù)與每天燒煤的噸數(shù)成反比例嗎?為什么?【參考答案】 (1)每天燒煤的噸數(shù)和燒煤的天數(shù),是相關聯(lián)的量?！?2)1×30=30 1.5×20=30 2×15=30 2.5×12=30 3×10=30 積相等,這個積表示這批煤的總噸數(shù)。 (3)成反比例,因為燒煤的天數(shù)與每天燒煤的噸數(shù)的積一定?！驹O計意圖】學生通過觀察、發(fā)現(xiàn)、概括經(jīng)歷了整個學習過程,逐步形成定向思維方式,為學會學習打好基礎。

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.
