北師大初中八年級數(shù)學(xué)下冊第一章復(fù)習教案
1．知識目標：在回顧與思考中建立本章的知識框架圖，復(fù)習有關(guān)定理的探索與證明，證明的思路和方法，尺規(guī)作圖等.2．能力目標：進一步體會證明的必要性，發(fā)展學(xué)生的初步的演繹推理能力；進一步掌握綜合法的證明方法，結(jié)合實例體會反證法的含義；提高學(xué)生用規(guī)范的數(shù)學(xué)語言表達論證過程的能力.3．情感價值觀要求通過積極參與數(shù)學(xué)學(xué)習活動，對數(shù)學(xué)的證明產(chǎn)生好奇心和求知欲，培養(yǎng)學(xué)生合作交流的能力，以及獨立思考的良好學(xué)習習慣.重點：通過例題的講解和課堂練習對所學(xué)知識進行復(fù)習鞏固難點：本章知識的綜合性應(yīng)用。【歸納總結(jié)】（1） 定義： 三條邊都相等 的三角形是等邊三角形。（2）性質(zhì)：①三個內(nèi)角都等于60度，三條邊都相等②具有等腰三角形的一切性質(zhì)。
北師大初中九年級數(shù)學(xué)下冊第一章復(fù)習教案
一、本章知識要點： 1、銳角三角函數(shù)的概念； 2、解直角三角形。二、本章教材分析： （一）.使學(xué)生正確理解和掌握三角函數(shù)的定義，才能正確理解和掌握直角三角形中邊與角的相互關(guān)系，進而才能利用直角三角形的邊與角的相互關(guān)系去解直角三角形，因此三角形函數(shù)定義既是本章的重點又是理解本章知識的關(guān)鍵,而且也是本章知識的難點。如何解決這一關(guān)鍵問題，教材采取了以下的教學(xué)步驟：1. 從實際中提出問題，如修建揚水站的實例，這一實例可歸結(jié)為已知RtΔ的一個銳角和斜邊求已知角的對邊的問題。顯然用勾股定理和直角三角形兩個銳角互余中的邊與邊或角與角的關(guān)系無法解出了，因此需要進一步來研究直角三角形中邊與角的相互關(guān)系。2. 教材又采取了從特殊到一般的研究方法利用學(xué)生的舊知識，以含30°、45°的直角三角形為例：揭示了直角三角形中一個銳角確定為30°時，那么這角的對邊與斜邊之比就確定比值為1：2。

四年級下冊《小英雄雨來》教案
1. 通過在教師指導(dǎo)下的獨立閱讀，初步理解內(nèi)容，學(xué)習小英雄雨來熱愛祖國、憎恨敵人、機智勇敢的優(yōu)秀品質(zhì)。2. 繼續(xù)練習用比較快的速度閱讀課文，讀后能說出每一部分的主要內(nèi)容。3. 練習給每一部分課文加小標題?！窘虒W(xué)重點、難點】用較快的速度閱讀課文，說出每一部分的主要內(nèi)容?！窘虒W(xué)時間】1課時?！驹O(shè)計理念】本文雖是略讀課文，但由于篇幅較長，可以安排一課時完成。教學(xué)中要練習用比較快的速度閱讀課文，培養(yǎng)學(xué)生的自讀能力。先通讀課文，用比較快的速度默讀課文，了解雨來是哪里人，生活在哪個年代？為什么稱他是小英雄？大體了解課文主要講了什么。全文研讀時一部分一部分地閱讀、思考，特別重點理解我們是中國人，我們愛自己的祖國這句話。在全面理解課文內(nèi)容的基礎(chǔ)上給各部分加小標題。最后進行總結(jié)擴展：觀看情景??；建議學(xué)生找來管樺小說的原著讀一讀?！窘虒W(xué)過程】一、激發(fā)情感，釋題引疑1、課件演示：小雨來與鬼子斗爭的片斷。問：你們想認識這位小英雄嗎？2、出示課題：(1) 理解課題：齊讀課題你從中知道了什么？小——指的是雨來的年齡小，是一個少年。英雄——指的“是雨來的特點。雨來——課文中的主人公。課題表現(xiàn)出文章的中心——英雄。(2) 引導(dǎo)到學(xué)生質(zhì)疑：看到課題后，你還想知道什么？（為什么稱雨來是小英雄？）（從課文中的哪些地方可以看出雨來是一位小英雄？）
北師大初中九年級數(shù)學(xué)下冊圓周角和圓心角的關(guān)系教案
解析：點E是BC︵的中點，根據(jù)圓周角定理的推論可得∠BAE＝∠CBE，可證得△BDE∽△ABE，然后由相似三角形的對應(yīng)邊成比例得結(jié)論．證明：∵點E是BC︵的中點，即BE︵＝CE︵，∴∠BAE＝∠CBE.∵∠E＝∠E(公共角)，∴△BDE∽△ABE，∴BE∶AE＝DE∶BE，∴BE2＝AE·DE.方法總結(jié)：圓周角定理的推論是和角有關(guān)系的定理，所以在圓中，解決相似三角形的問題常常考慮此定理．三、板書設(shè)計圓周角和圓心角的關(guān)系1．圓周角的概念2．圓周角定理3．圓周角定理的推論本節(jié)課的重點是圓周角與圓心角的關(guān)系，難點是應(yīng)用所學(xué)知識靈活解題．在本節(jié)課的教學(xué)中，學(xué)生對圓周角的概念和“同弧所對的圓周角相等”這一性質(zhì)較容易掌握，理解起來問題也不大，而對圓周角與圓心角的關(guān)系理解起來則相對困難，因此在教學(xué)過程中要著重引導(dǎo)學(xué)生對這一知識的探索與理解．還有些學(xué)生在應(yīng)用知識解決問題的過程中往往會忽略同弧的問題，在教學(xué)過程中要對此予以足夠的強調(diào)，借助多媒體加以突出.
北師大初中九年級數(shù)學(xué)下冊切線的判定及三角形的內(nèi)切圓教案
解析：(1)連接BI，根據(jù)I是△ABC的內(nèi)心，得出∠1＝∠2，∠3＝∠4，再根據(jù)∠BIE＝∠1＋∠3，∠IBE＝∠5＋∠4，而∠5＝∠1＝∠2，得出∠BIE＝∠IBE，即可證出IE＝BE；(2)由三角形的內(nèi)心，得到角平分線，根據(jù)等腰三角形的性質(zhì)得到邊相等，由等量代換得到四條邊都相等，推出四邊形是菱形．解：(1)BE＝IE.理由如下：如圖①，連接BI，∵I是△ABC的內(nèi)心，∴∠1＝∠2，∠3＝∠4.∵∠BIE＝∠1＋∠3，∠IBE＝∠5＋∠4，而∠5＝∠1＝∠2，∴∠BIE＝∠IBE，∴BE＝IE；(2)四邊形BECI是菱形．證明如下：∵∠BED＝∠CED＝60°，∴∠ABC＝∠ACB＝60°，∴BE＝CE.∵I是△ABC的內(nèi)心，∴∠4＝12∠ABC＝30°，∠ICD＝12∠ACB＝30°，∴∠4＝∠ICD，∴BI＝IC.由(1)證得IE＝BE，∴BE＝CE＝BI＝IC，∴四邊形BECI是菱形．方法總結(jié)：解決本題要掌握三角形的內(nèi)心的性質(zhì)，以及圓周角定理．
北師大初中九年級數(shù)學(xué)下冊直線和圓的位置關(guān)系及切線的性質(zhì)教案
解析：(1)由切線的性質(zhì)得AB⊥BF，因為CD⊥AB，所以CD∥BF，由平行線的性質(zhì)得∠ADC＝∠F，由圓周角定理的推論得∠ABC＝∠ADC，于是證得∠ABC＝∠F；(2)連接BD.由直徑所對的圓周角是直角得∠ADB＝90°，因為∠ABF＝90°，然后運用解直角三角形解答．(1)證明：∵BF為⊙O的切線，∴AB⊥BF.∵CD⊥AB，∴∠ABF＝∠AHD＝90°，∴CD∥BF.∴∠ADC＝∠F.又∵∠ABC＝∠ADC，∴∠ABC＝∠F；(2)解：連接BD，∵AB為⊙O的直徑，∴∠ADB＝90°，∴∠A＋∠ABD＝90°.由(1)可知∠ABF＝90°，∴∠ABD＋∠DBF＝90°，∴∠A＝∠DBF.又∵∠A＝∠C，∴∠C＝∠DBF.在Rt△DBF中，sin∠DBF＝sinC＝35，DF＝6，∴BF＝10，∴BD＝8.在Rt△ABD中，sinA＝sinC＝35，BD＝8，∴AB＝403.∴⊙O的半徑為203.方法總結(jié)：運用切線的性質(zhì)來進行計算或論證，常通過作輔助線連接圓心和切點，利用垂直構(gòu)造直角三角形解決有關(guān)問題．

區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句，都叫做主從復(fù)合句。賓語從句主要是中考必考的，是初中階段必掌握的從句，賓語從句主要是掌握三要素，所謂賓語從句，就是賓語在主從復(fù)合句當中充當賓語的一個句子，叫做賓語從句。主句的謂語動詞是及物動詞，后面如果是詞或者是短語的話，是簡單句，如果是句子的話，肯定是賓語從句。I know that he good at English.就是賓語從句，三要素，一要素是要注意連詞，連詞一共學(xué)了三類連詞，一類連詞是that口語當中可以省略，就像剛才說的那一句，I hear he is good at English.還有疑問代詞、疑問副詞，how where when，疑問代詞、疑問副詞。還有一類連詞weather是否的意思，不是狀語從句當中的如果，這一定要和如果區(qū)分開，這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序，要用陳述舉語序。比如說你家有幾口人，我們都說How many people are there in you family?但是這是簡單句，一旦說成賓語從句，你可以告訴我你家有幾口人嗎？Could you tell me how many people there are in you family ?
