北师大初中数学七年级上册绝对值的说课稿

  • 人教部编版七年级语文上册热爱生活,热爱写作教案

    三、实战演练1.明确题干要求师:阅读教材P18的写作实践三,读读题干和“提示”,然后集中讨论一下,你是如何理解这个写作实践暗含的要求的。预设(1)这个题目可以简单概括为成长中的事件,范围比较宽广,类似于经常碰到的《难忘的一件事》一类的作文题。(2)一定要注意“成长”这个关键词,在描述这个事件时,一定要写出自己人生体悟的变化。(3)要选择一件有意义的、使“我”成长的事来写,在文末还应升华主题,写出自己在经历这件事后得到的人生启示。2.补充写作提示师:为了帮助大家完成好这次习作,老师在教材的基础上,还另外补充了三条“提示”。课件出示:提示:1.选材要小。选取生活中的一两个片段来刻画人物、表达感情。从小事入手,于细微处见精神,以小见大,突出“难忘”“印象深刻”。2.叙事要详略得当。叙事要围绕中心,抓住重点,把最能体现事件意义、最能展示人物形象的言行、心理描写得真实而详细。同时,要讲究剪裁,选取典型的、能揭示事物本质的、有说服力的材料表达中心思想,做到详略得当,主次分明。

  • 大班数学《有趣的数字组合》说课稿

    本节课在我们大班年级组进行了一次研讨活动,本次的教学活动是在上次的基础上进行了修改,在开始部分我就利用幼儿园老师相同款式的两辆汽车直接导入,从而让幼儿想到车牌号码孩子们比较熟悉的数字组合,让本次数学活动渗透到我们平时的生活中,让孩子们对本次活动产生兴趣。使数学活动生活化。在最后一部分我以孩子们生活中随处可见的数字为内容,让孩子们发现生活中的数字,初步了解它们的不同用途,并且学会运用数字解决生活中的一些实际问题,从中体验活动的乐趣。这样不仅激发了孩子对数字的兴趣,也培养了孩子积极关注身边事物的情感态度。

  • 大班数学《学习5的加法》说课稿

    在教学上,我采用了摸花片给幼儿猜的形式引导幼儿复习5的组成。在教学信息和感知材料的呈现上,我选用了教具模型演示法,让幼儿明确操作的要求和进行操作的方法。在思维活动的组织上,我还通过讲解、比较的方法,将幼儿解决问题的种种策略展示出来,引导幼儿观察分析,找出哪一种是最好的。坚持使教法有利于突出教材重点,突破难点,符合幼儿认识规律和年龄特征。根据教学内容和采取的教学方法及手段,我教给幼儿一些学习的方法。操作法是幼儿学习数学的基本方法。幼儿通过操作进行学习,我对幼儿的操作给予必要的指导,让幼儿去探索、发现,这样的学法可以让幼儿获得宝贵的数学经验,在教给幼儿操作法的同时,考虑到本课内容和幼儿的学习情况,对于学习速率快的幼儿,我教给他们讨论交流的方法,学习速率慢的幼儿,我教给他们按顺序有重点地观察的方法,做到授之于渔。

  • 中班数学《得数是6的加法》说课稿

    按照心理学常识,幼儿对学习内容产生兴趣,就能自觉地排除内外主客观因素的干扰,集中注意力积极主动地投入学习,把学习当成愉快的事。因此,上课一开始进行复习时,就设计这样的导语:小朋友,我们已经学了很多加减法了,今天老师要来考考你们,看谁最能干,(点出复习题)最先做出老师出的这些题,好吗?在这种刺激下,人人都想当老师眼中的小能手,兴趣一下子就能调动起来。这是引导幼儿复习5以内数的加减;这是复习6的组成。在新课学习中,通过可爱的动物图片群和插入声音的播放,激发幼儿学习新知的欲望,引导幼儿感知、探索得数是6的加法。这是引导幼儿观察动物图片,发现数量关系,学习5+1和1+5,初步引导通过组成计算得数;然后出示4+2和2+4两个算式,让幼儿摆弄小棒探索得。

  • 中班数学《10以内的相邻数》说课稿

    幼儿数学逻辑思维训练简单的说可以包含了数、量、图形与空间、逻辑与关系四大领域。数以及数与数间的逻辑关系是事物各种属性关系在人脑中引起的综合反映,复杂且不易理解。,而我今天要说的相邻数对于4到5岁的幼儿尚没有在其大脑中形成这一概念,而与其接近的邻居关系却是幼儿日常生活中经常接触的,根据《幼儿园教育指导纲要》中提出的“教育活动内容的选择应既适合幼儿的现有水平,又有一定的挑战性;既贴近幼儿的生活来选择幼儿感兴趣的事物和问题,又有助于拓展幼儿的经验和视野”的要求,我设计了这堂《10以内的相邻数》的教学活动,希望孩子们在轻松愉快的游戏活动中和积极参与操作的过程中获得相关知识。

  • 中班数学《9以内的数量》说课稿

    课堂教学是幼儿数学知识的获得、技能技巧的形成、智力、能力的发展以及思想品德的养成的主要途径。为了达到预期的教学目标,我对整个教学过程进行了系统的规划,遵循目标性、整体性、启发性、主体性等一系列原则进行教学设计,设计了4个主要的教学程序。1、讲故事引起兴趣,在这个环节中,利用幼儿爱听、爱看的特点,我用故事《春姑娘来了》来吸引幼儿注意力。2、指导观察,判断数量。在这个环节中,我利用卡片,让幼儿说说图中有什么不同,培养幼儿观察能力。3、运用故事转折,挑起矛盾,引出相邻数。4、运用操作,加深幼儿对数量的认识、判断,几数量与数字匹配。从而进一步巩固这节课的内容,培养幼儿动手的能力

  • 中班数学《多变的圆形》说课稿

    拼图活动是幼儿园经常进行的活动,也是孩子们非常感兴趣的一项活动。以往的拼图活动比较注重拼图的造型设计和制作,对拼图活动本身所蕴藏的数学内涵挖掘不够。其实,拼图活动也是帮助幼儿了解整体与部分关系、掌握数概念的一个很好的载体,而且也符合新《纲要》“引导幼儿对周围环境中的数、量、形、时间和空间等现象产生兴趣,建构初步的数概念,并学习用简单的数学方法解决生活和游戏中某些简单的问题”这一精神。中班幼儿的思维仍带有直觉行动性,主要依靠动作进行,需要亲身体验,在操作探索中发现事物的特征。他们对于物体整体与部分关系的理解,必须借助于对具体物象的感知,拼图活动恰好为帮助幼儿感知数量的多少、整体与部分的关系提供了直观形象的支持。在日常的活动中,孩子们已经积累了一定的圆形拼图的造型经验,为本活动的开展奠定了良好的基础。

  • 中班数学《小刺猬的项链》说课稿

    二、说教材《指南》里的典型性表现说:中班的孩子能对事物或现象进行观察和比较,发现其相同与不同,喜欢动手动脑。他们常常在游戏时进行排列,比如拼插雪花片玩具,你会发现排列颜色是有规律的。积木搭建的小路,你也会发现小路石块也是有规律的,这些都说明他们对排序感兴趣。年龄层次方面,《小刺猬的项链》是幼儿园中班的下学期一节活动,幼儿的年龄大约都在4岁半—5岁。在生活经验方面,孩子们对排列有一定的生活经验积累,对周围常见的生活场景有一定的观察和比较;在知识方面,中班幼儿已经积累和建立了有关物体在颜色、形体和大小等特征差异上的简单排序的数学经验,可以更进一步地学习按照物的多个特征和数量进行不同的排序。在学习能力方面,吸纳外部信息的能力强,会掌握和理解新知识。三、说活动目标根据中班孩子的年龄特点和实际情况,我确立了认知、技能、情感这三方面的目标和重难点:(1)在欣赏与讲述中理解绘本内容同时巩固间隔排序的经验。(2)学习简单的按规律排序并大胆尝试自编规律。(3)懂得并感受分享是一件快乐的事情。四、说重点难点规律排列的数学活动重点是:在欣赏与讲述中理解绘本内容同时巩固间隔排序的经验。难点:学习简单的按规律排序并大胆尝试自编规律。

    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.

  • 人教版新目标初中英语八年级上册How do you make a banana milk shake教案2篇

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。

    “Go for it!” is based on “Task-Based Language Teaching”.
