  • 人教版新课标小学数学二年级上册两位数加两位数(不进位加) 说课稿

    人教版新课标小学数学二年级上册两位数加两位数(不进位加) 说课稿

    今天我说课的内容是二年级上册第二单元《100以内的加法和减法》的第一课时,两位数加两位数的不进位加法。教材通过参观博物馆的情境图引出两位数的不进位和进位加法。本节课主要解决不进位加法竖式计算中的对位和计算顺序问题。由于本节课是在学生已经掌握两位数加整十数、两位数加一位数的基础上学习的内容,这堂课的关键是引导学生运用这些已有的知识经验,借助位值图,通过自己的操作探究、合作学习,将新知识转化、纳入已有的认知结构,自主地学习两位数加两位数不进位加法的计算方法。因此本节课的目标确定为:知识与能力:1、充分利用直观手段,帮助学生理解和掌握笔算两位数加两位数的方法。2、培养学生观察、分析、解决问题的能力。过程与方法:运用直观手段,创设有意义的问题情境和游戏活动来组织教学,让学生通过动手操作、自主探索、合作交流等方法掌握算法,提高学习积极性,增强学习数学的兴趣。

    人教版新课标小学数学二年级上册两位数减两位数(不退位减)说课稿2篇

    说教材:(1)教学内容:人民教育出版社出版的九年义务教育六年制小学数学教科书第三册中的第16—17页的例1及“做一做”,练习三1、2、3、4、题。(2)教材分析(教材的前后联系,地位作用及编排意图):两位数减两位数是学生学习笔算减法的开始,也是以后学习多位笔算减法的基础。由于笔算减法是在口算减法的基础上进行教学的,所以教材先安排了口算整十数减整十数、两位数减整十数、两位数减一位数的复习,为理解笔算做好准备。教材由两位数减一位数的不退位减法口算引出两位数减一位数的不退位减法的笔算。说明这种口算题也可以写成竖式,用笔算。然后,对照直观图说明计算时要把相同数位对齐,从个位减起的计算顺序。(3)教学目标:根据教材的编排意图以及学生的实际,我确定本课的教学目标是:使学生理解笔算两位数减两位数的算理,掌握竖式的写法和计算方法,并能正确的笔算。培养学生知识迁移的能力和口头表达能力,培养学生仔细计算的良好学习习惯。

    人教版新课标小学数学五年级上册从不同角度观察两个物体说课稿2篇

    自主探究法:教学中强调以学生为主体,强调学生参与知识的形成过程,始终做到为学生提供充足的学习素材、创设充分学习的空间、时间,让学生自主探究,体验知识形成的过程,培养主动探究的能力。观察法:例1观察物体教学中的观察是很好的学习方法。例如,教学例1时,观察目的明确。教师通过让学生观察长方体物体学会从不同角度观察物体的方法。这一安排不仅给学生独立思考的机会,而且教给学生观察的思维方法。四、说教学程序在提出问题中,引发学生思考;在自主探索中,激发学生创新思维;在展示交流中,感受学生的个性;在总结陈述中,体验成功的乐趣;在联想记忆中进一步发挥学生的创造才能。在设计这节课时,我在尊重教材的基础上,力求体现新课标的新理念、新思想,导学案中设计了以下几个教学环节:

  • 人教版新课标小学数学五年级上册整数乘法运算定律推广到小数乘法说课稿

    人教版新课标小学数学五年级上册整数乘法运算定律推广到小数乘法说课稿

    “整数乘法运算定律推广到小数乘法”是在学生已经掌握了小数乘法计算、整数乘法运算定律的基础上进行教学的。教材通过几组算式,让学生计算出○的左右两边算式的得数,找出它们的相等关系,总结出整数的运算定律对小数同样适用。学好这部分内容,不仅培养学生的逻辑思维能力,而且以后能用本课所学的使一些小数的计算简便,也为以后学习用不同方法解答应用题起着积极的推动作用。2、教学目标的确定:根据教材特点,依据数学课程标准的要求及学生实际,我确定本课教学目标如下:(1)知识能力目标:理解整数乘法运算定律对于小数乘法用样适用,并能应用这些定律进行一些简便计算。(2)过程方法目标:引导学生在经历猜想、验证等数学活动中,发展学生的思维能力。(3)情感态度目标:通过小组合作学习,培养学生进行交流的能力与合作意识,体验到解决问题策略的多样性。结合相关内容,渗透“事物间是普遍联系”的观点,对学生进行辨证唯物主义的启蒙教育。

    人教版新课标小学数学六年级上册分数除法的意义和整数除以分数说课稿

    一.说教材。我说课的内容是人教版课程标准实验教科书六年级上册的分数除法单元中的例1和例2。例1是分数除法的意义认识,例2是分数除以整数的计算。在这之前学生已经掌握了整数除法的意义和分数乘法的意义及计算,而本课的学习将为统一分数除法计算法则打下基础。例1先是整数除法回顾,再由100克=1/10千克,从而引出分数除法算式,通过类比使学生认识到分数除法的意义与整数除法的意义相同,都是‘已知两个因数的积和其中一个因数,求另一个因数的运算’。例2是分数除以整数的计算教学,意在通过让学生进行折纸实验、验证,引导学生将‘图’和‘式’进行对照分析,从而发现算法,感悟算理,同时也初步感受数形结合的思想方法。根据刚才对教材的理解,本节课的教学目标是:1、理解分数除法的意义与整数除法的意义相同。2.理解分数除以整数的计算原理,掌握计算方法,并能正确的进行计算。

    二、以人为本,说策略。《数学课程标准》指出:“数学教学要紧密联系学生的生活实际,从学生的生活经验和已有的知识出发……”因此,结合本课教材特点、学生实际情况,我采取小组合作学习,引导学生应用学过的分数、小数互化的知识进行迁移、类推,学习新知识。同时,让学生在尝试探究的积极活动中获取新知,发展能力。三、以探为主,说流程。课堂教学是学生数学知识的获得、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地规划,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。设计了以下几个主要的教学程序:(一)设疑激趣,引入课题。“兴趣是最好的老师”,为了激发学生的学习兴趣,课一开始,我设计了一个童话故事,在故事中设计了帮助主人公比较2/5、42%、0.45的问题,然后引出课题。

    师:这是一种较为简便、应用广泛的方法,但有时候也要具体问题具体分析,做题时要合理灵活地选择计算方法。《研究学生如何学比研究教师如何教更重要。学生对新知识的学习必须以已有的知识和学习经验作为基础,因此正确分析学生的知识基础和学习经验就显得格外重要。我认为分数除以整数的教学基础在于以下几点:分数与小数的转化;分数的意义;分数乘法的意义;倒数的知识;商不变的性质等。这些知识在以前的学习中,学都有了足够的掌握。有了上面的分析基础,我觉得把研究新知识的权力教给学生,是完全可以的。》4、质疑与反思。师:对于这些方法,尽管大家的思维角度不尽相同,但是基本的想法是相同的,想一想我们是怎样解决问题的?生:用学过的倒数、商不变的性质解决的。师:对。用一句话概括就是运用旧知识解决新新问题。这是一种很重要的学习方法。5、实践体验练习巩固。

    新人教版高中英语必修2Unit 1 Cultural Heritage-Discovering Useful Structure教案一

    This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考:定语从句在复合句中的作用是什么? 关系词有哪些?定语从句在复合句中的作用相当于形容词,它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用,同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词,定语从句一般放在先行词的后面。

    The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.

    Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2.
