1 交通工具的比较此活动为小组活动。学生通过讨论找出到达某一城市可乘坐的各种交通工具,并选择最佳出行方式。Teacher:We’re going to Shanghai. How many ways can we use to get there? Yes, there are four ways: by bus, by plane, by train, by ship. Please discuss how you are going to get there.操作建议:(1)学生以小组为单位展开活动,谈论本组所选择的交通工具。(2)各组选代表向全班汇报,阐述本组所选择的交通工具的利和弊。完成任务所需要的语言结构:We can go there by ship. It’s more comfortable and cheaper than any other transportation.We can go there by bus. It’s cheaper but it takes longer time.2 哪个城市更合适?此活动具有挑战性。假设中国要举行2014年世界杯足球赛,分别从历史,人文,天气等方面对各城市(北京,大连,上海,昆明)进行比较,选择最佳举办城市。T: Imagine China is holding the 2014 FIFA World Cup. Which city do you think is the best for the World Cup, Beijing, Dalian, Shanghai or Kunming? Let’s work in groups. If you choose Beijing, please join the Team Red. If you chose Dalian, please join the Team White. If you choose Shanghai, please join the Team Blue. If you choose Kunming, please join the Team Green. Please show us its advantages. Then let’s see which team will win.

教学过程:一、导入新课。1、播放《保卫黄河》和《打虎上山》的音频,导入新课教学。师:请同学们听两段音乐,区别它们的音乐类型?学生回答:《保卫黄河》是歌曲,《打虎上山》是京剧。师:刚才,我们听到的《打虎上山》是现代京剧《智取威虎山》中的一个片断。杨子荣是生行的角色,但又不是传统意义上的老生或者武生,而是经过创新了的。下面,我们一起看一看影片《智取威虎山》的片段。2、介绍剧情,并观看影片视频。(教师播放视频《智取威虎山》。)师:1946年,我军某部团参谋长率部队进山,发动群众,以便消灭逃进威虎山的土匪座山雕。经过侦查,威虎山倚仗着地堡暗道,想要制胜最好是智取。参谋长派侦察排长杨子荣改扮土匪打入威虎山,杨子荣假意把联络图交给了座山雕,座山雕因其献图有功,劳苦功高所以提拔了杨子荣,被封为“老九”,并一起喝庆功酒。除夕夜杨子荣趁着土匪们为座山雕祝寿的时机,将匪徒灌醉,此时大部队赶到,全歼顽匪。这一段就是匪徒们在为杨子荣庆功的时候,杨子荣所唱的一段。今天,我们就来学习这一唱段。
京剧四大行当的介绍。1、媒体演示,教师讲解。师:京剧根据人物的性别,个性等把人物分成四大类,就是我们所说的四大行当:生、旦、净、丑。“生”一般指男性演员,在每个行当里,不同的年龄职业的人物又有不同的行当名,比如:画面上的这个叫老生,而这个年轻的叫小生,另外还有武生。“旦”是指女性角色,如年龄大的叫老旦,年纪轻的叫花旦,“净”则是指“花脸”,就是我们刚才我们介绍的有脸谱的角色。“丑”则是指诙谐滑稽或小奸小恶的人,就像画面上的这位水浒传中的石迁一样。2、请学生表演。师:介绍完四大行当,我们就要请出我们班里的四大名角来为我们演出,请同学们来做票友,如果他表演得好,就给他喝彩鼓掌,好不好?3、师拿出京锣伴奏,四位学生分别着生、旦、净、丑的服装依次出场表演、造型。4、请学生分辨角色,教师还可以为生角加上假胡须,以分辨老生与小生。
创设情景 兴趣导入问题 观察钟表,如果当前的时间是2点,那么时针走过12个小时后,显示的时间是多少呢?再经过12个小时后,显示的时间是多少呢?.解决每间隔12小时,当前时间2点重复出现.推广类似这样的周期现象还有哪些? 动脑思考 探索新知概念 对于函数,如果存在一个不为零的常数,当取定义域内的每一个值时,都有,并且等式成立,那么,函数叫做周期函数,常数叫做这个函数的一个周期. 由于正弦函数的定义域是实数集R,对,恒有,并且,因此正弦函数是周期函数,并且 ,, ,及,,都是它的周期.通常把周期中最小的正数叫做最小正周期,简称周期,仍用表示.今后我们所研究的函数周期,都是指最小正周期.因此,正弦函数的周期是.
解 由题意可得,今年的年产值为a·(1+10%) 亿元,于是明年的年产值为a·(1+10%)·(1+10%)= 1.21a(亿元).若去年的年产值为2亿元,则明年的年产值为1.21a =1.21×2 = 2.42(亿元).答:该企业明年的年产值将能达到1.21a亿元.由去年的年产值是2亿元,可以预计明年的年产值是2.42亿元.例3 当x=-3时,多项式mx3+nx-81的值是10,当x = 3时,求该代数式的值.解 当x=-3时,多项式mx3+nx-81=-27m-3n-81, 此时-27m-3n-81=10, 所以27m+3n=-91.则当x=3,mx3+nx-81 =( 27m+3n )-81=-91-81=-172.注:本题采用了一种重要的数学思想——“整体思想”.即是考虑问题时不是着眼于他的局部特征,而是把注意力和着眼点放在问题的整体结构上,把一些彼此独立,但实质上又相互紧密联系着的量作为整体来处理的思想方法.
教学目标1、知识目标:掌握等式的性质;会运用等式的性质解简单的一元一次方程。2、能力目标:通过观察、探究、归纳、应用,培养学生观察、分析、综合、抽象能力,获取学习数学的方法。3、情感目标:通过学生间的交流与合作,培养学生积极愉悦地参与数学学习活动的意识和情感,敢于面对数学活动中的困难,获得成功的体验,体会解决问题中与他人合作的重要性。教学重点与难点重点:理解和应用等式的性质。难点:应用等式的性质,把简单的一元一次方程化为“x=a”的形式。教学时数 2课时(本节课是第一课时)教学方法 多媒体教学教学过程(一) 创设情境,复习导入。上课开始,给出思考,(算一算,试一试)能否用估算法求出下列方程的解:(学生不用笔算,只能估算)
方法总结:在分辨一个图形是否为多边形时,一定要抓住多边形定义中的关键词语,如“线段”“首尾顺次连接”“封闭”“平面图形”等.如此,对于某些似是而非的图形,只要根据定义进行对照和分析,即可判定.探究点二:确定多边形的对角线一个多边形从一个顶点最多能引出2015条对角线,这个多边形的边数是()A.2015 B.2016 C.2017 D.2018解析:这个多边形的边数为2015+3=2018.故选D.方法总结:过n边形的一个顶点可以画出(n-3)条对角线.本题只要逆向求解即可.探究点三:求扇形圆心角将一个圆分割成三个扇形,它们的圆心角的度数之比为2:3:4,求这三个扇形圆心角的度数.解析:用扇形圆心角所对应的比去乘360°即可求出相应扇形圆心角的度数.解:三个扇形的圆心角度数分别为:360°×22+3+4=80°;360°×32+3+4=120°;
