第四篇：2.金木水火土(教案)

金木水火土

设计说明

这是一篇短小的儿歌，前两行数字与五行相对，后两行天地与日月相应。朗朗上口的诵读极易引发学生的兴趣，本课堪称识字小文的典范。培养学生主动识字的愿望和独立识字的能力，是课程标准着力强调的基本理念。因此，本节课教师以自主交流、小组互动为主体，努力将学生的识字愿望与课程标准理念相结合，引导学生“学习独立识字”，获得识字过程的丰富体验。

教学目标：

1.通过游戏、想象等方式理解课文，练习朗读。2.学习“一二三四五，金木水火土”一句。

3.认识田字格和笔画横，掌握正确的写字姿势，会写“一、二、三”。

课前准备

1.生字卡片。(师生)2.本课生字相对应的图片。(教师)3.课件。(教师)课时安排 1课时。教学过程

一、音频激趣，诵读导入

1.导言：听，一群小朋友在诵读什么呢？ 2.播放《金木水火土》音频文件，组织学生认真倾听3遍。3.交流：你听清小朋友诵读的内容了吗？你能尝试着说一说吗？ 4.播放《金木水火土》视频文件(带有字幕)，学生看着文字，跟着声音诵读。

设计意图：一年级学生对新鲜的事物充满好奇，尤其对朗朗上口的儿歌更是充满兴趣，上课伊始，就将学生的兴趣和注意力完全集中在教学内容上，达到了事半功倍的教学效果。

二、自主交流，了解韵文

1.自由朗读儿歌，遇到读不准的生字，先圈起来，再请教老师或者同学，反复读几遍。

2.指名朗读，集体订正后齐声诵读。3.小组合作：

(1)自由朗读小文，一边读一边想一想：每一句话讲了什么内容？(2)你读懂了什么？把你的想法告诉小组同伴。4.集体汇报，教师相机指导，需要注意以下几个方面：(1)第一行中“一二三四五”是数字。除此以外，你还知道哪些数字？(六七八九十等)(2)第二行中“金木水火土”指的是五行。教师讲解：古代的人喜欢用五行代表自然万物，他们认为自然界的一切都和“金木水火土”有关。

(3)第三行中“天地分上下”，“天地”指的是“天和地”，头上为天，脚下为地。我们就生活在天和地之间。(4)第四行中“日月照今古”，“日月”指的是“太阳和月亮”，太阳和月亮从古代照到今天，永久不变。

5.齐声诵读。

设计意图：韵文内容简单，教师引导学生在独立思考的基础上展开小组合作，在互动交流中获得对韵文内容的大致理解，教师再针对重点和难点加以点拨，必然实现水到渠成的教学效果。

三、合作学习，识记生字

1.小组合作：仔细观察老师发给同学的7张字卡，怎样能又快又准地记住它们？

2.学生汇报：大声朗读生字，并说一说你是怎样记住这个生字的。预设：

(1)“一、二、三”是三个长得很像的兄弟，一个横就是“一”，两个横就是“二”，三个横就是“三”。教师相机出示“上、下”的字理演示动画。

(2)“上、下”也是两个长得很像的兄弟，竖、短横在“一”的上面，就是“上”；竖、点跑到了“一”的下面，就成了“下”。教师相机出示“上、下”的字理演示动画。

(3)“四”和“田”长得很像，把“田”里面的“十”换成“ ”就是“四”。

(4)“五”字可以用猜字谜的方法识记——一个“工”人腰里挂着一把折尺()。

3.出示字卡，学生领读、自由读、小组读、开火车读。4.生字运用，在7个生字中选择自己喜欢的字，为它组词，比一比谁组的词语最多。如果这个字的词语较少，可以用其中一个词说一个完整的句子。

设计意图：引导学生自主学习，在小组互动交流的过程中，充分发挥学生的想象能力。在此基础上，教师给予必要的点拨、演示、资料补充，使学生对7个生字的字形和字义获得整体上的认识。

四、指导书写，掌握笔顺

1.复习书写姿势：书写时要做到哪“三个一”？(胸离桌子一拳远；眼离书本一尺远；手离笔尖一寸远)2.认识田字格：

(1)引言：从今天开始，我们就要练习写字了！我们先来认识一个写字小助手，它的名字叫田字格。

(2)动画展示田字格，学生一边观察动画中变红色并闪烁的部分，一边倾听田字格的自我介绍。

我叫田字格，我中间的横线叫“横中线”，横中线把我均匀地分为上下两部分。我中间的竖线叫“竖中线”，竖中线把我均匀地分为左右两部分。横中线和竖中线交叉，又把我分成了“左上格、右上格、左下格、右下格”四部分。

(3)学生观察田字格，用手指一指田字格的每一部分，再说一说它们的名字。

(4)教师小结：写字时，要注意笔画在田字格中的位置。3.指导书写“一、二、三、上”。(1)动画展示“横”“竖”两个笔画的书写，学生先观察它们的笔画走向，书空模仿，再观察两个笔画在田字格中所占的位置，最后在练习本中练写。

(2)动画展示“一”“二”“三”“上”的笔顺，学生一边观察一边用右手模仿书空。

(3)观察例字：请同学们仔细观察语文书第8页中的书写范例，看一看，每一个笔画占田字格的什么位置。

(4)教师范写，请同学们当小老师给老师讲一讲每一个笔画应该占田字格的什么位置。遇到学生说不准的地方，教师重点讲解。

(5)学生完成书中写字练习，先书空笔顺，再观察每一笔画在田字格中的位置，重点看清难写笔画的写法，然后描红，最后练习书写。(提醒学生注意书写姿势)(6)教师巡视，对个别学生予以指导。

(7)利用投影仪进行书写展评，鼓励学生多观察，掌握“横”“竖”的写法。

设计意图：本节课是一年级学生第一次书写，因此教师的书写指导必须到位。教师在本环节采用动画演示、课本观察、集中讲解、教师示范、自由练写等方法指导学生书写，并针对关键笔画进行了反复强调，使学生准确掌握所学汉字的书写，为后续的汉字书写打下坚实的基础。

教学反思

一年级的小学生刚入学，还没有形成良好的学习习惯。因此，本节课我注重对学生学习习惯的培养，注重对学生学习兴趣的激发。

1.以动画视频化解教学难点，激发学生的学习兴趣。刚入学的孩子并不是每个人都有拼音基础，有些孩子识字量少，又不会拼音，他们读起韵文来困难较多。小韵文音频和视频就解决了这一难题。另外，在写字过程中，我利用动画展示生字的笔顺，利用动画突出笔画在田字格中所占的位置，这都起到了直观示范的作用。学生的感知是清晰的，学生的理解是轻松的，学习的效果是实在的。

2.注重书写姿势的指导和要求，为学生夯实基础。现在的孩子大多不注重书写姿势，不注重握笔姿势，写着写着，姿势就发生了变化。因此，我在写字指导过程中反复强调书写习惯，反复纠正学生的错误习惯，并对学生进行正确的引导。

第五篇：2.因式分解教案

高初中衔接教材

因式分解

第二讲 因式分解

因式分解是代数式的一种重要的恒等变形，它与整式乘法是相反方向的变形．在分式运算、解方程及各种恒等变形中起着重要的作用．是一种重要的基本技能．

因式分解的方法较多，除了初中课本涉及到的提取公因式法和公式法(平方差公式和完全平方公式)外，还有公式法(立方和、立方差公式)、十字相乘法、分组分解法、求根公式法、配方法等等．

一、公式法(立方和、立方差公式)

a3b3(ab)(a2abb2)a3b3(ab)(a2abb2)

这就是说，两个数的立方和(差)，等于这两个数的和(差)乘以它们的平方和与它们积的差(和)． 运用这两个公式，可以把形式是立方和或立方差的多项式进行因式分解． 【例1】因式分解：(1)8x

3(2)0.12527b

3解：(1)8x323x3(2x)(42xx2).(2)0.12527b30.53(3b)3(0.53b)[0.520.53b(3b)2] (0.53b)(0.251.5b9b2).说明：(1)在运用立方和(差)公式分解因式时，经常要逆用幂的运算法则，如8a3b3(2ab)3，这里逆用了法则(ab)nanbn；(2)在运用立方和(差)公式分解因式时，一定要看准因式中各项的符号．

【例2】因式分解：(1)3ab81b 3

4(2)aab

76解：(1)3a3b81b43b(a327b3)3b(a3b)(a23ab9b2)．

(2)aaba(ab)a(ab)(ab)76663333a(ab)(a2abb2)(ab)(a2abb2)a(ab)(ab)(aabb)(aabb).a(a2b2)[(a2b2)2a2b2]a(ab)(ab)(a2abb2)(a2abb2).2222

a7ab6a(a6b6)a(a2b2)(a4a2b2b4)

二、分组分解法

从前面可以看出，能够直接运用公式法分解的多项式，主要是二项式和三项式．而对于四项以上的多项式，如mambnanb既没有公式可用，也没有公因式可以提取．因此，可以先将多项式分组处理．这种利用分组来因式分解的方法叫做分组分解法．分组分解法的关键在于如何分组．

【例3】把2ax10ay5bybx分解因式．

解：2ax10ay5bybx2a(x5y)b(x5y)(x5y)(2ab).说明：用分组分解法，一定要想想分组后能否继续完成因式分解，由此合理选择分组的方法．本题也可以将一、四项为一组，二、三项为一组，同学不妨一试．

【例4】把ab(cd)(ab)cd分解因式．

高初中衔接教材

因式分解

解：(1)原式(x22x1)(x22x8)(x1)2(x2)(x4).(2)原式(x22x15)(ax5a)(x3)(x5)a(x5)(x5)(x3a).四、配方法

【例10】因式分解(1)x6x16（2）x24xy4y2 解：(1)x26x16(x3)252(x8)(x2).(2)x24xy4y2(x24xy4y2)8y2 2(x2y)28y2(x2y22y)(x2y22y).说明：这种设法配成有完全平方式的方法叫做配方法，配方后将二次三项式化为两个平方式，然后用平方差公式分解．

五、拆(添)项法

【例11】因式分解x3x4 解： x33x24(x31)(3x23)

32(x1)(x2x1)3(x1)(x1)(x1)[(x2x1)3(x1)] (x1)(x24x4)(x1)(x2)2.说明：一般地，把一个多项式因式分解，可按下列步骤进行：(1)如果多项式各项有公因式，那么先提取公因式；

(2)如果各项没有公因式，那么可以运用公式法或分组分解法或其它方法(如十字相乘法)来分解；(3)因式分解必须进行到每一个多项式因式都不能再分解为止．
