例1用为每个小朋友准备春游食品的活动,由“应该每份同样多”引出“平均分”,让学生认识“每份分得同样多,叫平均分”。接着,通过例2、例3,让学生经历“平均分”的过程,建立起“平均分”的概念。二、说教学目标二年级学生年龄小,他们以直观思维为主,不易理解抽象的概念。虽然他们在平时的生活实践中已有一定的分物品的经验,但缺少平均分物品的实践经验。因此,他们对于“什么是平均分”,“怎样平均分物品”都感到比较困惑。所以,本节课的教学目标可以预设为:1.引导学生在具体情境中感受“平均分”,在分东西的实践活动中建立“平均分”的概念,理解“平均分”的含义。2.让学生经历“平均分”的过程,在具体情境与实践活动中明确“平均分”的含义,掌握“平均分”物品的不同方法。3.培养学生自主探究的意识和解决问题的能力。
一、创设情境,导入新课教师边放课件边讲故事):今天老师给你们讲一个“猴妈妈分桃”的故事。有一天,一群小猴到山下去玩,走着走着,看到一棵桃树上结满了又大又红的桃,就摘了很多。回家后,猴妈妈看到小猴们拿了这么多桃回来,可高兴了,说:“妈妈分桃给你们吃。”二、合作交流,探索新知1、动手操作,探究方法(1)提出问题。师:小猴摘了多少个桃?准备每只小猴分3个,可分给几只猴子?(板书:12个桃,每只小猴分3个,可以分给几只小猴?)(2)学生列式:12÷3=(3)分一分学生小组合作,动手分一分。(可以用其他的物体代替)(4)说一说分的过程可能有以下几种:第一种:先分给第一只小猴3个桃,再分给第二只小猴3个桃,然后给第3只小猴3个桃,最后3个桃正好分给第四只小猴。……12个桃可分4只猴子。
(二)解决问题,总结方法《新课程标准》主张充分挖掘数学教材潜在的“再创造空间”,让学生亲自经历将实际问题抽象成数学模型并进行解释与应用的过程,让学生最大限度地参与数学知识的发现、提出、形成、应用的再创造过程,以促进学生主动的发展。因此我创设了福娃晶晶为迎接奥运会做准备的数学情景,设计了四组有关7、8、9的用除法算式解决的数学问题。1、出示晶晶的问题:(1)做了56面彩旗,平均每行挂7面,能挂多少行?(2)做了56面彩旗,要挂成8行,平均每行挂多少面?(3)做了49颗五角星,平均分给7个小朋友,每人多少颗五角星?(4)准备了27个气球,平均9个摆一行,能摆多少行?2、解决晶晶的问题:让学生根据"友情提示"的要求完成自学内容后再小组交流、全班交流。在交流过程中引导学生观察:56÷8=7和56÷7=8这两个算式,从而发现一句乘法口诀可以计算两个除法算式。
一、教材分析及学生分析:数学课程标准在各个学段中,安排了“数与代数”、“空间与图形”、“统计与概率”、“实践与综合应用”四个学习领域。其中“统计与概率”中统计初步知识在一、二年级已经涉及,但概率知识对于学生来说还是一个全新的概念,它是学生以后学习有关知识的基础,并且概率问题是一个与社会生活关系密切的重要问题。因此在第一学段中对于“不确定现象”由感性升华到理性认识非常重要。对于三年级的孩子来说,由于他们的年龄和思维特点,他们一般只能在感性的层面理解可能性的知识,因此,在教学中,我们密切关注并考虑学生已有的经验知识,在学生已有的经验体会的基础上,设计各种活动丰富学生的经验积累,从而进行可能性知识的构建。
一、说教材《分数乘法》是人教实验版六年制上册的分数乘法的第一课时的内容。这部分内容的学习是在学生已经学习了整数乘法的意义很分数加法计算的基础上进行的。在这个内容中,分数乘整数的意义和整数乘整数的意义相同,都是求几个相同加数的和的简便运算,只是这里的相同加数变成了分数,同时分数乘整数又是分数乘分数、分数乘加、乘减混合运算的基础上,因此必须使学生切实掌握好。基于以上原因,我确定了如下目标。知识目标:使学生理解分数乘整数的意义,掌握分数乘整数的计算方法。能力目标:培养迁移转化的能力。情感目标:培养学生尝试探究,合作学习的好习惯。为了使学生能比较顺利地达到教学目标,我确定了本节课的教学重点:使学生理解分数乘整数的意义,掌握分数乘整数的计算。教学难点:分数乘整数的计算方法。二、说教法根据新课程理念,学生已有的知识,生活经验,结合教材的特点,我采用了以下的教学方法:
1、课件出示教材例1的座位图。教师说明分组方法,从左往右依次为第1列、第2列、第3列直至第6列,从前往后依次为第1行、第2行直至第5行。请学生用自己的语言说说张亮的位置,要求尽可能简洁。当多位学生说完之后,教师组织全体学生评价哪种方法最简洁?当学生一直认同第2列第3行是最简洁的描述方法时,教师板书:第2列第3行。学生主动参与,体会最简表述方法的优越性。2、此时,教师再提出你能用这种方法描述王艳的位置吗?赵强呢?及时反馈,利用最简方法描述其他两位同学的位置。3、让学生完成一个记录游戏:教师快速地报出第几列第几行,让学生记录。学生可能记录不下来。这时教师提出我们要进一步简洁,不用文字,用数字和符号把它的位置记录下来。通过游戏使学生感受到“数对”产生的必要性。学生用自己的方式填写,教师可以选取几位代表在黑板上写,然后提出这些同学记录方法不一样,但有什么相同的地方?引导学生观察发现都有数字2和3,都表示第2列第3行,
对于一个非银行业相关专业毕业的求职者来说,能够有这样一个机会进入农信工作,对我来说既是机遇又是挑战。诚然,对于一个对银行业务不甚了解的门外汉来说,在银行这样的单位里,在完全陌生的领域中,我必须从头学起。在我刚进农信的几天里,认识这里的同事,以及熟悉这里的工作环境对我来说是首先需要解决的问题。在很短的时间里,我就已经认识了大家,渐渐开始熟悉了这里的一切为了熟悉农信的各种业务和基本知识,我看了不少如柜台、信贷、稽核、会计准则、财务等方面的业务书籍,在接触到一些不太熟悉的术语以及科目时,我就会在网上查找相关的解释,如果实在不明白,我就向同事们请教,大家也都不厌其烦地给我讲解,并且想方设法让我去接触更多我尚不熟悉的知识。在上柜台实际操作的这段日子里,由开始时的紧张与生涩到现在的淡定与熟练,虽有自己的努力,更多的是与各位同事的鼓舞与支持离不开的,在我做的好的时候,他们给与了我肯定,在我出错的时候,没有了责骂,而是理解与教导,他们用过来人的身份传授给我切身经验,这样的好同事,怎能不让我加倍努力呢?
一、教材分析 1、教材内容及所处地位综合实践活动是在新一轮基础教育课程改革中应运而生的新型课程。所谓综合实践活动,主要指以学生的兴趣和直接经验为基础,以与学生学习生活和社会生活密切相关的各类现实性、综合性、实践性问题为内容,以研究性学习为主导学习方式,以培养学生的创新精神、实践能力及体现对知识的综合运用为主要目的一类新型课程。具有以下特点: 1、基于兴趣与直接经验。2、回归生活世界。3、立足实践。4、着眼创新。5、以研究性学习为主导学习方式:(1)以转变学生的学习方式为出发点。(2)强调知识的联系和综合运用。(3)注重过程。(4)强调开放。(5)重视师生互动。四年级下册综合实践活动课程要培养学生对生活、学习的积极态度,使他们具备一定的交往合作能力、观察分析能力、动手操作能力;要让他们初步掌握参与社会实践的方法,信息资料的搜集、分析和处理问题的方法以及研究探索的方法;使学生形成合作、分享、积极进取等良好的个性品质,成为创新生活的小主人。2、单元内容分析本教材包括?方法与指导?和?活动与探究?两部分内容, ?方法与探究? 主要是让学生掌握如何进行采访,通过一系列活动,掌握采访的准备、注意事项、具体实施,及最后的交流总结,培养学生交往能力。 ?活动与探究?包括六个主题,主题一我们身边的标志,通过让学生认识标志,体会含义。学会分类,最后学会制作标志,循序渐进,蕴含了创新、守规、审美等能力的培养;主题二早餐与健康通过谈论,调查、分析讨论培养学生交流总结能力,树立健康生活意识;主题三,有趣的丝网花,通过制作培养学生合作、审美、动手能力;主题四巧手做风筝继续对学生进行培养;主题五植物的扦插与嫁接,与现实生活联系密切,通过活动掌握方法,体验快乐,体验劳动的乐趣;主题六争做小小志愿者,通过了解体验志愿者的活动,丰富阅历,培养学生的服务意识,自身获得提升与发展。教材的重点、难点:重点:学会交流,提升能力;认识各种标志,学会制作;学会健康的生活;通过制作丝网花、风筝、植物的扦插于嫁接,学会制作,提高动手能力,通过体验小小志愿者,提高服务意识。难点:教学中让学生亲身参与、主动实践,在实践中综合运用所学知识解决各种实际问题,提高解决实际问题的能力。学习基础:四年级学生已具备了一定的实践能力,因此要逐步培养学生一些探究问题的方法,提高学生的动手意识,能够从生活和学习中挖掘自己感兴趣的活动主题,能够试着和同学展开小组合作学习,在有效的活动中不断提高学生的动手与创新的潜能。

And after finishing listening for the first time, the students need to solve the following tasks.
The theme of the section is “Describe space facts and efforts to explore space”. Infinitives are one of non-finite verbs, as the subjects, objects, predicative, attributes and adverbials. This unit is about space exploration, which is a significant scientific activity, so every scientific activity has strong planning. Therefore, using the infinitives to show its purpose, explanations or restrictions is the best choice.1. Learn the structure, functions and features of infinitives.2. Learn to summarize some rules about infinitives to show purpose and modify.3. Learn to use infinitives in oral and writing English. 1. Learn the structure, functions and features of infinitives.2.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?
另一方面,其余的人反对这个计划,因为它可能会导致一些不好的影响。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我坚信探索太空不仅能够使我们了解宇宙的起源而且能够帮助我们更好地走进未来。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.为了给人类的短期和长期问题提供更新和更好的解决方法,我认为我们应该花更多的时间和金钱来探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看来,年轻人过度依赖手机是不对的,因为它们可能会对他们的身心健康都有害。最近你班同学就“人类是否应该进行宇宙探索”这个问题进行了激烈的讨论。有人认为,探索宇宙不仅让人类更好地了解宇宙的发展,还可以用来指导农业生产,以及把一些探索太空的高新技术用于现实生活;也有一些人认为探索太空花掉了大量的人力物力;影响了人们的生活水平。请你根据以下情况写一篇报告并发表自己的观点。注意:1.写作内容应包括以上全部要点,可适当发挥,使上下文连贯;
