1.宇涵同学音频说出自己出行困扰。2.小组合作讨论设计往返旅游线路:宇涵同学渴望大家的帮助,就请小组成员一起合作,帮宇涵设计一份往返旅游线路,我这里有一份从南京到大连的不同交通工具所需时间及费用的参考表。小组讨论,并将小组一致认为最适合的设计方案,写在设计表中!3.各小组派代表分享设计方案4.设置情境,学以致用:同学们设计的方案都很好,如果从我们目前所在的城市,到宇涵的家乡“南京”你又会如何选择?5.小结:看来,同学们都能根据自己不同的需求选择合适的出行方式。活动二:了解传统交通方式的作用1.观察思考:在我国,一些地区至今还沿用着传统的交通工具(出图),大家仔细观察,想一想,为什么它们能沿用至今?你还知道哪些传统的交通工具?2.小结:是呀,无论时代如何变迁,现代交通工具多么发达,都要选择适合我们的交通工具。在享受它们带来的便捷时,做到绿色出行,减少拥堵污染,那我们的生活一定会更加美好。
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.

Copy the new words这一步是用于热身的,同时也可以让他们复习一部分的表示人体部位的单词,扩充知识.学习语言的过程也是一个不断积累的过程,复习旧知识,增添新知识.通过小游戏,强化学生对Does she/he have…这个句子的运用能力.通过复习,自然的引到下面新知识的学习。充分利用表格,由句子到对话,再到文章,让学生循序渐进. 提高学生的综合语言运用能力,运用以前学过的知识来解决身边的问题.Period 5 (Section B 3a—3c, selfcheck)教学内容与分析:
Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class. Step 5 ( planning a party )First read the conversation in the box together. Then ask the students to turn to page 88.Write down everything you have to do next week. Write in all the things you have to do . Ask the students to look at the list. Ask them “What day are you free?” This is when you can have your party. Step 6 (Self check 1 )Let the students to fill in the blanks with the words given. Change the forms of the words if possible. Then make their own sentences. The answers are: visit, playing, have to, study, comeStep 7 (Self check 2)Imagine you are Marie. Read the information and look at your schedule. Write replies to the invitation.
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”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii. Recite the new words and expressions about the last school trip in the aquarium, including their pronunciation and intonation

教学目标1.知识目标:(1)学习What are you going to be when you grow up?/How are you going to do that?句式。(2)学会用英语描述有关职业的表达法。2.能力目标:(1)能够谈论为实现理想所做出的打算和安排。(2)能够谈论未来自己与他人理想的职业及原因。(3)能用英语描述课余时间的活动安排,最终具备表达综合信息的能力。3.情感目标:新学期到来之际,让他们在学习、体育、饮食、特长、读书等方面制定计划,教育学生合理安排自己的课外生活,思考自己的理想职业及适合自己的职业。教学重点、难点本单元的重点为“be going to”表将来,want to be, what,where, when,how引导的特殊疑问句。难点是语言目标的实现。教材分析本单元以I am going to be a basketball player为话题,共设计了三部分的内容:一、Section A该部分有4个模块。第一模块围绕Do you think these jobs are interesting?这一话题展开思维(1a)、听力(1b)、口语(1c)训练;
《打电话》这节课是人教版小学数学五年级下册的综合应用。是继“烙饼问题”、“沏茶问题”“等候时间”之后又一次向学生渗透运用运筹思想解决实际问题的内容。教材的素材是学生生活中所熟悉的,合唱队在假期接到一个紧急任务,老师要打电话“尽快”通知到15名队员。让学生帮助老师设计一个打电话的方案,并从中寻找最优的方案。通过这个实践与综合应用,旨在让学生进一步体会数学与生活的密切联系以及优化思想在生活中的应用,培养学生应用数学知识解决实际问题的能力,同时通过画图的方式发现事物隐含的规律,培养学生归纳推理的思维能力。因此,我认为,本节课的目标应定位于:1、让学生尝试在解决问题的多种方案中寻找最优方案。通过动手操作、画图模拟等方式发现事物隐含的规律;
5、交流。学生可能有按照长方体的表面积的计算方法计算的。交流时注意引导学生比较哪种方法最简便,同时明确在正方体表面积的计算公式中为什么要乘6。7、质疑问难。8、揭示表面积的含义:刚才我们在求做长方体和正方体纸盒至少各要用多少硬纸板的问题时,都算出了它们6个面的面积之和,长方体和正方体6个面积的总面积,叫做它的表面积。(三)巩固练习,扩展应用。(10分)数学来源于生活,又服务于生活,学生学到的知识通过应用才能真正理解和掌握。1、书中的习题。15页练一练、17页1、5题。通过有目的的基本练习、巩固练习、综合练习,使学生进一步加深了对新知识的理解。强化了学生运用新知解决实际问题的能力,使学生形成了一定技能技巧。
五、教学评价《数学课程标准》指出:“有效的数学学习活动不能单纯地依赖模仿和记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。”这节课的设计着力让学生通过参与有效的实际操作、观察比较来概括出“找次品”的最佳方案。把学生的学习定位在自主建构知识的基础上,建立了“猜想——验证——反思——运用”的教学模式。让学生体验解决问题策略的多样性及运用优化的方法解决问题的有效性。培养学生的自主性学习能力和创造性解决问题的能力。(一)创设情景通过身边生活实例,为学生创设问题情景,让数学问题生活化,一上课就吸引住学生的注意力,调动他们的探究兴趣,为后面的教学做好铺垫,使学生进入最佳的学习状态。让学生充分感受到数学与日常生活的密切联系。
这样设计,既复习了新课所必备的旧知,又自然合理地引入新课,一开始就紧紧吸引了学生的注意力,激发起学生的求知欲。(二)探索新知1、质数和合数的意义(教学例1)。(1)让学生拿出印发的写有例1原题的练习纸,利用学过的求约数的方法,写出1-12每个数的所有约数。(2)按照约数个数的多少进行分类,提出以下问题让学生讨论:①每一个数约数的个数相同吗?各有多少个约数?②按照每个数的约数个数的多少,可以把这些数分成几类?你认为是一类的用同一符号标出来。检查学生讨论情况并提问:你是怎样分的?为什么这样分?每一类各包括了哪几个数?让学生充分发表意见,然后师生共同归纳,并用投影出示三种分类情况:
(二)教材分析《分数和小数的互化》是在学生学习了分数的意义分数与除法的关系和分数的基本性质的基础上教学的。学习这部分内容是为以后学习分数和小数的混合运算打下基础。例1是教学小数化分数。教材突出“先把小数化成分母为10、100、1000……的分数再写成最简分数”这一转化过程。例2时教学6个数的大小比较,从中学习如何把分数化小数,教材按照已掌握的分数与除法的关系和分数的基本性质,提出问题引导学生想出多种方法把分数化成小数。本节课的内容,体现了数学知识的内在联系,学生通过学习这部分知识,将为今后学习分数与小数的混合运算打下良好的基础。(三)教学目标1.知识目标:是学生理解并掌握分数和小数、小数和分数互化的方法,能正确地进行分数与小数、小数与分数之间的互化。2.能力目标:培养学生的观察、归纳和概括能力。3.情感目标:体验合作学习的快乐,感受数学在生活中的应用价值,渗透“事物之间互相联系、互相转化”的辩证唯物主义思想。
三、说学法学生是学习的主体,应在学习中充分发挥自己的主体能动作用,所以本节课学生主要采用以分组实践、自主探究、合作交流为主要形式的“探究学习法”,目的是通过丰富多彩的小组活动,观察实践,以合作学习促进自主探究。首先是小组合作观察药箱和其他立体图形的活动,我先让小组成员独立思考,然后组内讨论交流,达成共识,最后小组成员一齐操作。然后是小组议一议的活动,老师先引导学生:关于观察物体,你有什么新发现?学生在独立思考的基础上讨论交流,各抒己见,共同促进。组与组之间也有交流。学生合作过程中,教师适当的启发、引导,学生的学习方式主要是自主、合作和探究性的。
1、教材分析《同分母分数加减法》是人教版五年级下册第五单元的内容。本节教学内容包括分数加减法的含义、同分母分数加减法的计算方法和连加、连减三个部分。这部分内容是在学生学习整数、小数加减法的意义及其计算方法,分数的意义和性质,以及在三年级上册学过的简单的同分母分数加减法的基础上进行教学的。为异分母分数加减法的学习搭好阶梯。2、学情分析相对整数加减运算而言,分数的加减运算对于大多数学生来说是比较困难的,但是学生对简单的同分母分数加减法计算有一定基础。学生已有一定的生活经验,并有一定的分析和解决问题的能力,会有条理地表达自己的思考过程。3、教学目标(1)知识与技能:掌握同分母分数加减法的计算方法,理解相同单位的数相加减的算理及含义,并能够正确熟练地计算。(2)过程与方法:能够利用所学知识解决生活中的实际问题,培养学生应用知识的能力。(3)情感态度与价值观:通过小组合作学习,培养学生的合作意识和学好数学的信心。
1、完成练习十五第1题。(1)学生独立完成计算。(2)指名板演,交流计算方法。提问:你是按照什么运算顺序计算的?指出:分数加减混合运算的运算顺序与整数相同,参与运算的几个分数,可以分步通分,分步计算;也可以一次通分,再计算。计算结果要约成最简分数。[练习十五里异分母分数加减混合运算的纯计算题比较少,仅第1题里有4道。教学中适当补充三个分数加减混合运算的练习也是可以的,但不要耗费学生过多的学习精力。如果学生计算发生错误,要仔细分析原因,有针对性地采取有效的解决措施。]2、完成练习十五第2题。(1)读题,理解题意,说说自己的思路。(2)学生独立完成解答。10(3)+ 5(1)+ 6(1)= 30(9)+ 30(6)+ 30(5)= 30(20)= 3(2)(小时)(3)交流汇报,集体评价。3、完成练习十五第3题。(1)学生独立完成(1)、(2)小题,说说自己是怎样想的?(2)鼓励学生根据题中的已知条件提出用分数加、减法计算的不同问题,可以是一步计算的,也可以是两步计算的,并让学生尝试解决提出的一些问题。
