1.2 第三教時 篇2
教材: 子集目的: 讓學生初步了解子集的概念及其表示法,同時了解等集與真子集的有關概念.過程: 一 提出問題:現在開始研究集合與集合之間的關系.存在著兩種關系:“包含”與“相等”兩種關系. 二 “包含”關系—子集1. 實例: a={1,2,3} b={1,2,3,4,5} 引導觀察. 結論: 對于兩個集合a和b,如果集合a的任何一個元素都是集合b的元素,則說:集合a包含于集合b,或集合b包含集合a,記作aíb (或bêa)也說: 集合a是集合b的子集.2. 反之: 集合a不包含于集合b,或集合b不包含集合a,記作aëb (或bëa) 注意: í也可寫成ì;ê也可寫成é;í 也可寫成ì;ê也可寫成é。3. 規定: 空集是任何集合的子集 . φía 三 “相等”關系1. 實例:設 a={x|x2-1=0} b={-1,1} “元素相同”結論:對于兩個集合a與b,如果集合a的任何一個元素都是集合b的元素,同時,集合b的任何一個元素都是集合a的元素,我們就說集合a等于集合b, 即: a=b2. ① 任何一個集合是它本身的子集。 aíaì¹② 真子集:如果aíb ,且a¹ b那就說集合a是集合b的真子集,記作a b③ 空集是任何非空集合的真子集。④ 如果 aíb, bíc ,那么 aíc 證明:設x是a的任一元素,則 xîa aíb, xîb 又 bíc xîc 從而 aíc 同樣;如果 aíb, bíc ,那么 aíc⑤ 如果aíb 同時 bía 那么a=b 四 例題: p8 例一,例二 (略) 練習 p9 補充例題 《課課練》 課時2 p3五 小結:子集、真子集的概念,等集的概念及其符號 幾個性質: aíaaíb, bíc þaícaíb bíaþ a=b 作業:p10 習題1.2 1,2,3 《課課練》課時中選擇
1.2 第三教時 篇3
一、復習:子集、補集與全集的概念,符號二、討論:1.補集必定是全集的子集,是否必是真子集?什么時候是真子集?2.aíb 如果把b看成全集,則cba是b的真子集嗎?什么時候(什么條件下)cba是b的真子集? 3. 研究 三、例題例一 設集合 cua={5},求實數a的值.
例二 設集合 例三 已知集合 且a中至多只有一個奇數,寫出所有滿足條件的集合.例四 設全集u={2,3, },a={b,2}, ={b,2},求實數a和b的值.(a=2、-4,b=3)一、 作業 《精析精練》p9 智能達標訓練

1.2 第三教時 篇10
教學過程 :
一、復習檢查:
簡述老孫頭的形象。
二、研習新課。
1.這節課我們來研讀一下,作者還著力刻畫了誰?他的思想品質如何?
郭全海。
分馬前,他抓住時機教育群眾,“分了東西可不能忘本啊”,分馬時,他雖然在最前分馬,卻“隨隨便便”牽一頭;當老孫頭馬跑了,他立即“翻身騎上”自己的騾馬去追,累得“人馬都氣喘吁吁”。當他發現老王太太不中意自己的馬時,他就主動提出跟老王太太換馬,并又召集積極分子開會,啟發大家要從長遠利益出發跟老王太太換馬。當老王太太換走了老田太太的馬,郭全海又做老田太太思想工作,決定“開春馬駒歸你”,使矛盾圓滿解決。
從這些方面可以看出,郭全海是一個忠于黨,大公無私,毫不利已專門利人的人。
2.小結中心思想:
本文通過對分馬換馬的描寫,反映了翻身農民分得勝利果實的喜悅心情。表現了先進農民大公無私的精神以及廣大農民在黨的領導下,思想覺悟迅速提高。
3.體會本文寫人敘事詳略得當的特點。
元茂屯參加分馬的有三百來戶人家,作者只寫了其中十來個人,這十來個人,也安排得有詳有略,主次分明。說說看,哪些人寫得詳;哪些人寫得略?
詳寫:郭全海(主),老孫頭(次)
略寫:趙大嫂子,白大嫂子,老田夫婦,老王太太等。
為什么要這樣安排?
小結:這樣能突出中心思想,有略寫配合,使得文章內容完整、全面,寫出翻身農民的歡樂和他們覺悟的提高。同時,在各種人物對比映襯中,更能突出主要人物的性格特征。
