1.热身(warm-up) (1)全班齐唱歌曲“How call I Get to the Zoo?’’ (2)师生一起吟唱第一单元的歌谣,要求学生一边吟唱,一边用手打节拍。 2.预习(Preview) 教师对学生有关My Dream Vacation的短文做出总体评价,并请几名写得有创意的学生朗读他们的短文,教师针对其内容提问,如:“Where are you going? What are you going to do? How are you going to there等。教师根据课前的准备,在最后一名学生朗读完文章并回答了问题以后,简化并板书该学生的回答,将其改编成为一首小歌谣,如: Where are you going? What are you going to do? I’m going to the ZOO to see the monkeys. I’m going by bike.I’m going On foot. I live near the ZOO.So I won’t take a train. 教师拍节拍示范朗读自己改写的新歌谣,学生模仿吟唱新歌谣。 3.新课呈现(Presentation) Let’s chant 在以上活动的基础上,教师放Let’s chant部分的录音,学生静听并试着跟读,再看着文字吟唱。师生可进行问答式吟唱,并在小组间展开比赛。 Listen and match
教案点评: 本课时在上一课时的基础上,进一步在情景中学习句型Is this your...? He/She looks... What’s he/she? They look... Are they...? 本课时的内容和学生的实际生活贴近,学生对该话题感到亲切,教学新句型时教师运用学生的家庭照片,在师生的对话中自然的呈现新知和操练句型,有助于学生更好的掌握和操练对话。本堂课教学层次分明,教师引导适当,发挥了学生在学习中的主体地位第六课时重点:单词nurse, doctor, farmer, driver的拼写。难点:I’m going to be a…教具准备:1.图片nurse, doctor, farmer, driver2.教材相配套的教学录音带3.单词卡片教学过程(35sk.com):一 热身/复习(Warm-up/Revision)1.口语练习:How many people are there in your family?Who are they?What are they?2.让学生改编B部分的chant, 然后表演出来。教师对表现出色的应即使给予奖励。二 呈现新课 (Presentation)1.教师出示表示表职业的单词卡让学生认读,并贴在黑板上。2.做找朋友的游戏。让学生把图片贴到相应的单词下。
2.预习(Preview) 看字母,说职业 教师出示职业名称单词的首字母,让学生说出整个单词。如:w-writer;d-driver/doctor,a-accountant/actor/actress;T-TV reporter等o 3.新课呈现(Presentation) (1)从看字母说职业名称引出TV reporter,教师拿出一些名人照片说:“Now you’re a TV reporter.You’re going to interview a famous person.You don’t know who he/she is .But you know he/she is someone in the pictures.”给学生五次提问的机会,让他们根据教师的回答找出正确的人物。以下问题供参考: What does he/she do? What’s h is hobby ? Is he strong/thin/tall? Where does he/she live? (2)心有灵犀 请两名学生(sl和s2)上来,每人拿着纸和笔分别站在教室的两边。教师提问:“What does s1’s father do?”站在台上的两名学生分别把答案写在各自的纸上。如果两人的答案完全相同,两人就算获胜。教师继续问问题“What does …’s…do?”全体学生一起写出答案,谁写的答案正确就可以得一分。 Listen and match (1)教师说:“Do you want to know more about Liu Yun?’’学生回答后教师说:“Please listen and find out.’’教师放本部分录音,学生认真听。
一、组织教学:检查学生用具准备情况二、讲授新课:1、引入阶段:引趣,挂出宇宙飞船,宇航员,飞碟等图案师问:图上的物体是些什么?是用来干什么的?挂出两幅完整的太空,科幻作品。介绍简单的太空知识和人类深索太空奥秘的活动。
解析:整个阴影部分比较复杂和分散,像此类问题通常使用割补法来计算.连接BD、AC,由正方形的对称性可知,AC与BD必交于点O,正好把左下角的阴影部分分成(Ⅰ)与(Ⅱ)两部分(如图②),把阴影部分(Ⅰ)绕点O逆时针旋转90°至阴影部分①处,把阴影部分(Ⅱ)绕点O顺时针旋转90°至阴影部分②处,使整个阴影部分割补成半个正方形.解:如图②,把阴影部分(Ⅰ)绕点O逆时针旋转90°至阴影部分①处,把阴影部分(Ⅱ)绕点O顺时针旋转90°至阴影部分②处,使原阴影部分变为如图②的阴影部分,即正方形的一半,故阴影部分面积为12×10×10=50(cm2).方法总结:本题是利用旋转的特征:旋转前、后图形的形状和大小不变,把图形利用割补法补全为一个面积可以计算的规则图形.三、板书设计1.简单的旋转作图2.旋转图形的应用教学过程中,强调学生自主探索和合作交流,经历观察、归纳和动手操作,利用旋转的性质作图.

"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。)

说明:在帮Li Lei提建议的同时,教育学生如何学好英语。第三课时教学目标1. 语言目标:a) 词汇: Original, in style, haircut, the same as.b) 语言结构:My friend wears the same clothes and has the same haircut as I do.2. 能力目标:大多数学生能够谈论自己喜欢哪种服装,提高查找信息的能力。3. 情感目标:学会如何与朋友相处,要有自己对时尚的看法。教学重点掌握一些重要词汇。教学难点学会谈论问题,并能提出书面建议。◆教学突破首先针对Erin的问题,提出个人的建议,模仿2c部分的对话展开双人交际Pair-work;听老师诵读3a部分的信件,并找出LEFT OUT的问题所在;学生完成3b部分的内容,给Left Out提出书面的建议;学以口头形式提出自己目前存在的某个问题,讲给大家听,让同学们给自己提出一个建议,并作笔录;学生两、三个人分成一组,随意性地进行口语交际,谈论P14的第4部分的某个问题,相互交换意见。
区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?
This activity introduces some new vocabulary and provide oral practice using the target language.Task 1 . Ask four students to stand in front of the class, and the teacher asks them the following questions as a reporter.1.What are you going to do when you grow up?2.What are you going to do next week?3.What are going to do after school?The students will give different answers, then ask a good student to report what they said.I am going to e a doctor.What did she say?----------She said she was going to be a doctor.I am going to have a party on Friday night.What did he say?-------He said he was going to have a party on Friday night.I am going to do my homework.What did she say ?------ She said she was going to do her homework.I am going home after school.What did she say?-----She said she was going home after school.Say In this unit we are going to learn to use words like to report what someone said.Task 2. Read the instructions. Then ask a student to read the four questions. And write the words on the Bb. Explain what soap opera is.Task 3. Ask the students to Look at the pictures, point out the TV screens in the picture. Ask one girl to read what Marcia said.What did Marcia say? She said She said she was having a surprise party for Lana on Friday night. Repeat the other pictures in the same way.Activity3. Listen and number the pictures in activity 1a.
(一).知识方面: 1.培养学生能运用过去进行时来描述、谈论过去某个时间正在发生的事情或动作的意识和能力,能就过去某个时间正在发生的动作做出正确的描述。 2.培养学生的想象力和角色扮演的合作能力。 3.培养学生讲述过去发生的事情经过的能力。能正确运用一般过去时来讲述故事。 (二).技能方面: 1.本单元的语言目标是Talk about past events and tell a story(谈论过去的时间和讲述一个故事),围绕这一目标,要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必须学习standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地点的词,以便为上述句型提供语言材料。2.学习过去进行时的有关知识。Was/were+现在分词,是该时态的表达式。 3.在学习过程中,要区分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.这两种由when和while引导的状语从句的句型结构。注意它们的不同。
一、导入:1、请一位同学和老师一起做游戏:老师有红、黄、蓝三种颜色,两人各滴一种颜色在画纸上,再用吸管吹,让颜料混合、互相渗透。让全班同学观察两种颜色互相渗透的变化过程,并且把看到的变化分别在小组里说一说。2、请两位同学上台,再做一次游戏,把看到的变化经小组讨论后,在班上说一说。3、教师小结:两种流动的颜色在互相混合、渗透的过程中变幻无穷,今天,我们一起动手试试,看看这种美妙的变化。4、揭示课题:流动的颜色
在课堂上,我通过点播和启发,充分调动学生的主体意识,让学生体会成功的喜悦。在这里放手让学生找规律,顺势而导地将其引向“精彩”,使课堂教学在“预设”与“生成”的融合中放出异彩。当然了,更重要的是培养学生掌握找规律的数学思考方法,发展了数学能力。在记忆口诀之前,我让学生找找口诀中的规律,然后让学生运用自己发现的特点去记忆口诀,这样学生就不会感到枯燥疲惫,而会主动积极的去记忆,让学生感到自己才是学习的主人。课堂上我还设计了《西游记》中的一段故事情节帮助记忆口诀,通过有趣的人物形象,大大地激发了学生对口诀的兴趣。对于特别难记的口诀,让学生讨论交流、寻找规律,有效地激发孩子的探究心和创造欲,学生想出了联系上、下句记忆,或者用以前学的乘法口诀进行记忆等方法。(四)分层练习,由浅入深。这里的练习主要分基本练习及拓展性综合练习(解决实际问题)两类。首先,通过对口令、口算练习,进一步巩固口诀。
3、在学生已有了乘法口诀的数学模式后,引导学生运用已有经验,亲自参与其它乘法口诀的学习,充分发挥学生的主体作用,发展学生的思维。4、多采用提问让学生思考的方法,让学生在操作过程中想老师提出的问题,培养学生的抽象概括能力。如:在摆了两根小棒后问学生:现在摆了几根小棒?可以用几表示?摆了几个2根?用乘法算式应怎样表示等。5、运用磁性黑板摆实物,让学生能够通过观察实物直观感知,如:问2个2是多少?学生实在不能想的可以通过看图数数来完成,这样便可以照顾学习有困难的学生。学生已经对乘法的含义有了初步的理解,掌握口诀就比较容易;但是,要熟记乘法口诀并准确的运用还需花较大的精力和时间,因此,要引导学生学会由加法到乘法,再到口诀的归纳法,由易到难,循序渐进的方法。如:2个2,可以用加法22=4,再到写乘法算式2×2=4,再归纳出口诀“二二得四”;先引导学生说出1个2是多少?编出口诀,再引导说出2个2是多少,编出口诀等等。
《8的乘法口诀》是《义务教育课程标准实验教科书数学》二年级上册的内容。乘法口诀是学生学习乘法的开始,它是学生今后学习表内除法和多位数乘、除法的基础。教材的呈现是在学生学了“2——7的乘法口诀”以后,所以教材呈现形式没有给出一个完整的乘法算式和一句完整的口诀,意在让学生主动归纳出8的乘法口诀。体现了学生学习独立性要求的编写意图。熟练口算表内乘法,是每个学生应具备的最基本的计算能力。因此,本课的重点应该是让学生理解8的乘法口诀的形成过程;难点是怎样去熟记并利用乘法口诀来解决生活中的实际问题。基于对教材的理解,我把教学目标定为:(1)认知目标:通过观察、探索,使学生知道8的乘法口诀的形成过程。(2)能力目标:通过教学活动,培养学生的观察能力、判断能力、合作交流和语言表达能力。(3)情感目标:激发学生的学习兴趣,让学生体验生活中处处有数学,会用数学知识解决生活中的问题。
1、教材简析“直角的初步认识”这节课出自人教版义务教育课程标准实验教科书数学课本二年级上册第三单元。这单元的内容是角和直角的初步认识,是在学生已经初步认识长方形、正方形和三角形的基础上教学的。“直角的初步认识”是学生初步认识了角,知道角的各部分名称后,在这基础上出现的。教材通过引导学生观察国旗、椅子、双杆上的角,来说明这些角都是直角。然后让学生通过折纸做直角,加深对直角的认识。再借助三角板来说明要判断一个角是不是直角,可以用三角板上的直角来比一比。最后让学生学会用三角板画直角。学好这部分知识,能为今后进一步认识直角以及学习其它几何图形打下牢固的基础。2、教学目标(1)结合生活情境,使学生初步认识直角,会用三角板判断直角和会画直角。(2)通过看一看,比一比,折一折,画一画等教学活动,培养学生的观察能力,判断能力和实践能力。
加减混合是在连加连减的基础上进行的,学生有了一定的基础,在计算方法上没有什么大的问题,那么我就重要引导学生理解加减混合运算的意义。本课是从学生熟悉的乘坐公共汽车的生活情境引入的。教学时,我让学生用数学语言描述情境图中的“动作过程”,提出问题,并联系过程列式计算。学生都有乘公交车的经历,所以理解起来非常容易。这类加减混合式题是在连加、连减的基础上进行教学的,由于运算顺序与连加、连减的顺序相同,所以教学时让学生进行类推,先填好分步计算的第一个竖式,并计算出得数,再填写第二步计算的竖式,并计算出结果,然后让学生自己想简便写法的竖式。把学生的主动探索和老师的适时引导有机结合,使学生再轻松愉快的氛围中提高学习能力。
