"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

一.说教材我今天说课的内容是义务教育课程标准北师大版七年级下册第四单元第二节的《用关系式表示的变量间关系》。在上节课的学习中学生已通过分析表格中的数据,感受到变量之间的相依关系,并用自己的语言加以描述,初步具有了有条理的思考和表达的能力,为本节的深入学习奠定了基础。二.说教学目标本节课根据新的教学理念和学生需要掌握的知识,确立本节课的三种教学目标:知识与能力目标:根据具体情况,能用适当的函数表示方法刻画简单实际问题中变量之间的关系,能确定简单实际问题中函数自变量的取值范围,并会求函数值。过程与方法目标:经历探索某些图形中变量之间的关系的过程,进一步体会一个变量对另一个变量的影响,发展符号感。情感态度与价值观目标:通过研究,学习培养抽象思维能力和概括能力,通过对自变量和因变量关系的表达,培养数学建模能力,增强应用意识。
由于任何一个一元一次不等式都能写成ax+b>0(或<0)的形式,而此式的左边与一次函数y=ax+b的右边一致,所以从变化与对应的观点考虑问题,解一元一次不等式也可以归结为两种认识:⑴从函数值的角度看,就是寻求使一次函数y=ax+b的值大于(或小于0)的自变量x的取值范围。⑵从函数图像的角度看,就是确定直线y=ax+b在x轴上(或下)方部分所有的点的横坐标所构成的集合。教学过程中,主要从以上两个角度探讨一元一次不等式与一次函数的关系。1、“动”―――学生动口说,动脑想,动手做,亲身经历知识发生发展的过程。2、“探”―――引导学生动手画图,合作讨论。通过探究学习激发强烈的探索欲望。3、“乐”―――本节课的设计力求做到与学生的生活实际联系紧一点,直观多一点,动手多一点,使学生兴趣高一点,自信心强一点,使学生乐于学习,乐于思考。4、“渗”―――在整个教学过程中,渗透用联系的观点看待数学问题的辨证思想。
2.送信。实物投影仪演示反馈。(1)方法说明。你是怎么想的?(2)错误纠正。分层校对:做完的先互相批改,然后集体先校对丁当组题,再校对一休组题。重点讲评一休组题目。六、总结今天你有哪些收获?(1)退位减法要注意什么?不要忘记退位。(2)退位减法的方法。为学生提供学习材料,让学生通过活动联系生活实际学习新知,让学生感受到数学源于生活,用于生活;采用分层教学,整个学习过程都是学生在小组中合作研究、探索中完成的;然后通过多种形式的练习加以巩固;注重学习过程的开放;通过小组合作,培养学生善于发表自己的观点,会倾听同学的意见的能力。同时也培养学生学会提出问题、解决问题的能力。
一、教学内容:两位数减一位数和整十数(不退位)(课本第67页)。二、教学目标:1、知识与技能:让学生经历探索两位数减一位数和整十数(不退位)的计算方法的过程,掌握计算方法,能正确地口算。2、过程与方法:让学生经历自主探索、动手操作、合作交流等方式获得新知的过程,积累数学活动的经验,体会数学知识与日常生活的密切联系,增强应用意识。3、情感态度与价值观:进一步培养学生学习数学的热情,以及积极思考、动手实践并与同学合作学习的态度。三、教学重点:掌握两位数减一位数和整十数(不退位)的口算方法。四、教学难点:理解算理,把握两位数减一位数与两位数减整十位数在计算过程中的相同点与不同点。五、教具准备:课件、题卡、等。六、教学过程:(一)、创设情境,提出问题。
二、互动交流,理解算法1.出示教科书第22页的情境图,提问:他们在干什么?你获得了什么信息?能提出什么问题?怎样列式?2.师:今天我们就学习一位数除三位数的计算方法。(板书课题:一位数除三位数)3.师:怎样计算238÷6呢?你能用估算的方法估计出大致结果吗?4.学生尝试独立完成例3的竖式计算。师:在这道题中被除数最高位上是2个百,2个百除以6,商不够1个百怎么办?师:谁能说一说商3个十的3写在商的什么位置上?为什么?教师边板演边说明:用除数6去乘3个十,积是18个十,表示被除数中已经分掉的数,写在23的下面。23减18得5,表示十位上还剩5个十。师:接下来该怎么办?(把被除数个位上的8落下来,与十位上的5合起来继续除。)师:最后结果是多少?5.启发学生想一想:如果一本相册有24页,一本相册能插得下这些照片吗?2本呢?
教学目标1、通过教学,学生懂得应用加法运算定律可以使一些分数计算简便,会进行分数加法的简便计算.2、培养学生仔细、认真的学习习惯.3、培养学生观察、演绎推理的能力.教学重点整数加法运算定律在分数加法中的应用,并使一些分数加法计算简便.教学难点整数加法运算定律在分数加法中的应用,并使一些分数加法计算简便.教学过程设计一、复习准备(演示课件:整数加法运算定律推广到分数加法)下载1.教师:整数加法的运算定律有哪几个?用字母怎样表示?板书:a+b=b+a(a+b)+c=a+(b+c)2.下面各等式应用了什么运算定律?①25+36=36+25 ②(17+28)+72=17+(28+72)③6.2+2.3=2.3+6.2 ④(0.5+1.6)+8.4=0.5+(1.6+8.4)教师:加法交换律和结合律适用于整数和小数,是否也适用于分数加法呢?这节课我们就一起来研究.二、学习新课(继续演示课件:整数加法运算定律推广到分数加法)下载1.出示:下面每组算式的左右两边有什么关系?
一、自觉依法纳税(二)我国税收“取之于民,用之于民” 1、税收的含义与基本特征 【学生活动】学生思考后回答。 【教师活动】税收是国家为实现其职能,凭借其政治权力,依法无偿地取得财政收入的基本形式。 【教师活动】税收具有强制性、无偿性和固定性的基本特征。[1]强制性:不管你愿意还是不愿意,都必须交税。[2]无偿性:交了税,没有补偿,更不会返还。[3]固定性:征税是有标准的,不是无止境的,按标准收到一定数量即算完成纳税。 2、税收的性质 【教师活动】展示多媒体图片,观察税收性质是什么? 【学生活动】分析图片,税收的性质。 【教师活动】每个人都与税收紧密地联系在一起,我们天天享受到的公共物品,无不有赖于税收。接受教育要有学校,看病要有医院,出行要有道路,保障国家安全要有国防,防洪、发电要有水利工程,这些都要依靠国家的税收来为公众提供公共服务。 【教师活动】播放国家免费为新冠肺炎患者治疗的视频。 【教师活动】劳动人民是税收的最终受益者,我国的税收是取之于民、用之于民的新型税收。
一、游戏活动激趣,认识对称物体1、游戏“猜一猜”:课件依次出示“剪刀、扫帚、飞机、梳子”的一部分,分男、女生猜。2、认识对称物体:1)师质疑:为什么女生猜得又快又准呢?2)小结:像这样两边形状、大小都完全相同的物体,我们就说它是对称物体。(板书:对称)二、猜想验证新知,认识轴对称图形(一)初步感知对称图形1、将“剪刀、飞机、扇子”等对称物体抽象出平面图形,让学生观察,这些平面图形还是不是对称的。2、师小结:像这样的图形,叫做对称图形。(板书:图形)(二)猜想验证对称图形1、猜一猜:出示“梯形、平行四边形、圆形、燕尾箭头”等平面图形,让学生观察。师:这些平面图形是不是对称图形?怎样证明它们是不是对称图形?
一、复习导入1、口答:最大的一位数是几?最小的两位数是多少?这两个数相差多少?2、数数:10个10个地数,从10数到100; 1个1个地数,从91数到99; 问:99加1是多少?3、导入:你会从100开始接着往后数吗?今天开始我们将要学习更大的数,下面请你们观察这幅图。二、讲授新课1、出示主题图。(1)观察这幅图,说一说画面上正在发生什么事情?(2)看着画面你想知道什么问题?引导学生估算画面上的体育馆大约能坐多少人?2、板书课题:1000以内数的认识。3、教学例1。(1)数一数。每人数出10个小方块,说说你是怎么数的?板书:一个一个地数,10个一是十。
1、复习万以内数的认识。 请同学们先来回忆一下,我们学了万以内数的哪些知识? 回忆学了万以内数的数数、读数、写数、数的组成、数位的含义、数的顺序和大小比较、近似数以及整百、整千数的加减法……2、下面先请大家独立做教材第3题,然后集体订正。 指名让学生说一说是怎么做的?3、写一写,再读一读。① 千位上是2个千、百位上是5个百、个位上是6个一。② 二千五百零六。4、 下面复习用计数单位表示数,独立完成书上第4题,想一想是怎样做出来的。5、 复习近似数。请同学们看教材第5题,找出这段文字中哪些数是近似数?并画出来。再请同学回答。
