The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life. Thank you for your listening !5.Revise your writing each other.Does he/she explain how music has changed his/her/someone else’s life?Are some of the rhetorical devices included and used properly ?Does he/she talk about how music makes him/her/someone feel?Is the first word in each sentences capitalised?Does he/she use correct punctuation ?

一、说教材《认识人民币》是人教版小学数学一年级下册第五单元的第一课时的内容。本课是让学生认识各种面值的人民币,初步知道人民币的基本知识和如何使用人民币,提高社会实践能力;另一方面使学生加深对100以内数的概念的理解,体会数概念与现实生活的密切联系。二、说教学目标1、学生能够正确的认识各种面值的人民币,知道人民币的单位元、角、分,知道1元=10角。 2、能较熟练地辨认各种面值的人民币。 3、感受数学与实际生活的密切联系。。教学重点:认识各种面值的人民币,知道人民币的单位元、角、分,知道1元=10角。教学难点:人民币的等价兑换。三、说教法、学法在整个教学过程中采用小组合作交流的学习方式,为学生设计猜一猜,看钱、认钱,唱歌、分类等活动。
教学重难点:学会人民币单位间的换算和简单的加减法计算以及学会看物品价格的表示形式第三部分 设计意图1. 通过购物情景的创设,使课堂富有真实的生活气息。2. 为学生搭建知识的攀升阶梯,让学生经历数学知识的发展形成过程。3. 将所学知识应用现实生活中,解决实际问题。第四部分 教学过程一、创设情境,激趣导入。1.孩子们你们喜欢交朋友吗?(喜欢)在班级里谁是你的好朋友呀?(学生回答)你们喜欢我吗?我也想和你们做朋友。今天我还给同学们带来了一个新朋友?你们看它是谁?电脑出示米老鼠你们想和它做朋友吗?想和它做朋友上课就得好好表现,他们才愿意做你们的朋友.谁说一下,上课怎样做才是好好表现呢?(要专心听见,勇敢发言,)老师看看勇敢的你在哪里?
上课的开始,我以上半年学习的《雪地里的小画家》中的小青蛙对主人公问:当时谁没参加啊?学生马上就会想到小青蛙。进而我接着谈话激趣。春天到了,小青蛙呀,从洞里钻出来了,它经过一冬的修养啊,本领变大了。它今天来到了我们的课堂上和你们见面了,它还做了一首优美的小诗《青蛙写诗》送给你们。
1.统计是数学课程标准规定的四个领域之一。传统上比较注重统计图表等知识和根据统计图表回答问题的教学,而课程标准则更加重视学生对数据统计过程的体验,学习一些简单的收集、整理和描述数据的方法,认识统计的作用和意义。这部分内容比较繁琐,分小组进行合作学习是有效的学习方式。2.教师将教科书的盆花变成纸花,努力为学生创设一些数据,使教材更具有实用性。但是,对于有条件的学校,可以带领学生进行实地统计,效果会更佳。3.教师要善于捕捉课堂上学生的反馈信息,创设轻松愉悦的课堂气氛。本课中,教师设计的让学生学四种动物的叫声,不仅活跃了课堂气氛,又引入到下一个问题的探讨。4.充分尊重学生的选择,让学生用自己喜欢的方法进行统计,使他们的情感、态度在其中得到了充分体验。
刚才大家只用了几个简单的图形就摆出了这么多不同的的规律,可见数学真奇妙!认真观察这些作品,他们贴得都有规律吗?谁有问题想问大家?生可能问:看到这些规律,你有什么想说的吗?谁能看出黑板上摆的第一条规律?第三条继续摆,下一个是什么图形?最后一条该怎么分组,规律就看得特别清楚了?这些规律有什么相同和不同的地方?……师生共同总结出: 今天我们研究的规律都是有关图形的规律;摆放的图形的颜色、方向、形状以及个数的变化都可出现一些有趣的规律。聪明的设计师都习惯运用规律来布置我们周围的环境,我们也可以应用规律来美化我们的生活。六、反思拓展,总结全课师:这节课快上完了,评价一下自己吧.这节课你快乐吗?你会了吗?有没有遗憾?生活中有了规律就有了美,希望同学们课后继续去发现美,创造美,让我们的生活更加多姿多彩!
低年级儿童好奇、好动,知识的学习和巩固应考虑儿童的年龄特征,因此,学生的学习应以活动为主,从学生的兴趣入手。基于学生在生活中已经对“左右”积累了一定的感性经验,但不一定准确判断的情况下,我给学生充分的时间和空间,让学生通过说、找、做、摆、看、练的活动,逐渐加深对“左右”的位置关系的认识。1、说。是从生活经验入手,说左右手分别能做哪些事,这是对左右的初步认识。2、找。是找像左右手这样的好朋友,这是对左右的进一步了解。3、做。这是听口令做动手的小游戏。除了能调动学生的学习积极性,还能加深学生区别左与右。4、摆。通过摆学具,使学生把对左右的认识变成得心应手的知识。5、看。这是让学生观察由于他们的转动,右边事物的不同,初步体验左右的相对性。6、练。达到巩固认识“左右”的位置关系,培养学生会运用所学知识解决生活中的实际问题的能力,体验数学与生活的密切联系。
2、学生小组间的问答:“Where are you from?”“I’m from…”(根据孩子自己制作的头饰回答)3、请几个小组开火车问答:“Where are you from?”4、教师出示钟表(把时间调到下午):“Good afternoon!”教师带上Mr. Black的头饰(走到一位学生面前)说:“Good afternoon! My name’s Mr. Black. I ’m from China.”孩子根据自己的情况回答:“Good afternoon, Mr. Black. I’m Xiao Dong . I’m from China.”教师提问一组孩子。然后请学生到前面来扮演Mr. Black.5、教师带着Mr. Black 的头饰走到台前,说:“I have a friend in our class. Do you know who’s she?”教师指着扮演Amy的同学说: “This is my friend Amy.”(引导全班孩子问好)Ss: Nice to meet you.A: Nice to meet you, too!Ss: Where are you from?A: I’m from America.Ss: Welcome!6、教师播放Let’s talk部分的课件, 学生观看对话。跟读、模仿,分角色给课件配音。7、小组分角色练习对话。8、小组表演对话。趣味操练 (Practice)1、Listen and order the cards: 将课文图片打乱顺序,让孩子听一听, 摆一摆。2、表演Let’s talk部分的对话。
二、新授环节新授环节是本堂课的重点,我主要分为6步来突破语言点,步步为营,环环相扣,达到既定目标。1、首先我用touch and guess游戏来呈现新授单词present,通过CAI展示各种生日礼物,如衣服,书本,玩具等让学生操练单词:Books can be a present等,操练时做到词不离句。2、接着我借助多媒体让学生说说自己想要的礼物I want a_____,同时我将实现准备的实物和图片作为礼物赠送给他们,新授句子Here’s a present for you,激发学生开口说的兴趣,又为接下来的操练提供了资源。我利用刚才分发的礼物采用游戏 “I’m a little bee”, (S1:I’m a little bee. Today is my birthday. S3:Here’a present for you。)四人小组合作操练这个句型。既避免了操练的机械性又调动了学生的积极性,而且提供了让每个学生开口说的机会,关注学生个体的发展。3、当学生Act完后,我对一学生说:Oh, little bee, what’s your present? Open it and see。让学生打开礼物呈现实物生日贺卡教学词汇birthday card。既做到了呈现自然,又渗透西方文化知识,培养学生跨文化交际意识。
一、说教材分析教材分析:本部分内容是在学生认识了认数的第一阶段—20以内各数认识的基础上,扩展到认数的第二阶段—100以内各数的认识。本阶段的数概念不仅是学习100以内数计算的基础,也是认识更大的自然数的基础。它在日常生活中有着广泛的应用,因此必须使学生切实学好。在分析教材的基础上,灵活的运用教材,我认为开始的主题图,如果10只一群地出示,虽然有利于学生估数,但这样学生能很快地10只10只地数出羊群只数是100,在后面数100个物体的个数时,就会受其影响而10个10个地数,这样的数法,要在学生会逐个数数的基础上自然生成,其实,它比一个一个地数要高一个层次,数数单位由“一”变成了“十”,不利于学生把100以内的数逐个数出来,因此,我把主题图的出示放在了一个一个数物体之后。
3.第三个环节是:巩固深化,应用新知。首先让学生完成课本76页练习十三的第一题。主要是检验学生对复式折线统计图绘制方法的掌握情况,并能对复式折线统计图所表达的信息进行简单的分析、比较。练习时,先让学生在书上独立完成,再说一说制图的正确步骤,我用多媒体演示,并提醒学生注意最高气温和最低气温对应的折线各用什么表示,还要写上数据和制图日期,根据学生的制作情况,还可以组织学生讨论一下,两条折线上的数据怎样写就不混淆了?最后让学生看图回答题中的问题,这里重点帮助学生弄清“温差”的含义,另外,在回答最后一个问题时,学生可能会说“我喜欢看统计图”,我就重点让学生说说为什么喜欢看统计图?从而让学生进一步体会复式折线统计图的直观、形象的优越性
这样设计,既复习了新课所必备的旧知,又自然合理地引入新课,一开始就紧紧吸引了学生的注意力,激发起学生的求知欲。(二)探索新知1、质数和合数的意义(教学例1)。(1)让学生拿出印发的写有例1原题的练习纸,利用学过的求约数的方法,写出1-12每个数的所有约数。(2)按照约数个数的多少进行分类,提出以下问题让学生讨论:①每一个数约数的个数相同吗?各有多少个约数?②按照每个数的约数个数的多少,可以把这些数分成几类?你认为是一类的用同一符号标出来。检查学生讨论情况并提问:你是怎样分的?为什么这样分?每一类各包括了哪几个数?让学生充分发表意见,然后师生共同归纳,并用投影出示三种分类情况:
我说的第二个内容是:比较大小。这节内容的编写意图是先让学生利用实物的多少比较相应数的大小,在利用计数器比较所表示数的大小,接着在直接比较数的大小。以上过程体现了儿童从具体到抽象的认知特点,便于学生掌握比较两个数大小的一般方法。另外,教材提供了充分的并且贴近学生生活实际的教学资源,我们应尽量利用好它,并积极地动手制作学具,以便提高教学效果。以下是教学流程及说明。第一大环节出示例8鸡蛋图,观察比较。这幅图的情景非常贴近农村孩子的生活,学生一看就会感到很亲切,教师可以用兴奋的语言介绍画面,使画面生动起来,同时也明确了学习任务,比如可以这样说:“明明家养了两只母鸡,小鸡下蛋了,明明真高兴,他每天都帮着妈妈捡鸡蛋,而且明明是个细心的孩子,他把两只鸡下的蛋放在各自的盘里,让两只鸡比比赛,看谁下得蛋多。小朋友,你们知道哪只鸡下的蛋多吗?我们快来数一数吧!
