一年级数学说课稿上册篇一
《买文具》是义务教育课程标准实验教科书数学(北师大版)一年级下册第六单元《购物》的第一课时。本节课突出让学生在活动中了解、认识人民币,解决实际问题。本节是本单元的第一节课,由于学生对人民币的认识已经有一定的生活经验,因此教材中创设了一个非常有趣的情境——买文具,让学生在购物活动中初步认识人民币,理解人民币的功能。通过“买文具”、“认一认”等一系列活动让学生认识小面额的人民币,并对小面额人民币上的数字、图案等有初步的了解,然后进一步让学生掌握元、角、分之间的关系。最后通过“填一填”来了解人民币之间的兑换,以培养学生解决简单问题的能力。
1.在现实情境中认识元、角、分,并重点了解它们之间的关系。
2.通过购物等活动,体验数学与生活的密切联系,理解人民币的功能。
3.培养合理使用和爱护人民币的意识。
通过“买文具”这一真实、有趣的情境,激发学生的学习兴趣,让学生初步理解人民币的功能。然后通过看、拿、想、说、换、比等手段,加深学生对小面额人民币的认识。在此过程中,教师不断创设情境,让学生掌握元、角、分之间的关系,并且真正体会1元钱的币值,发展学生解决问题的意识和能力。同时,培养学生合理使用和爱护人民币的意识,也让学生感受到生活中的数学无处不在,将数学课与生活融合在一起。
课件、图片、人民币、多媒体。
教学流程
师:同学们,你买过东西吗?今天,老师想带你们去商店看一看,你们愿意吗?(出示商店情境图)这个商店是卖什么的?(自由发言,引导学生说完整的话,准确运用数量词)在商店里你都看到了什么?(自由说)这么多的文具你想买什么呢?(让一名学生说)那你用什么买呀?(人民币)你认识钱吗?今天老师给大家准备了一些咱们中国通用的钱——人民币(实物人民币)。
【借助文具商店这一情境,引出本节的主题——人民币,并揭示人民币的功能。】
1.师:现在,你们想仔细去看一看吗?下面请每个小组拿出信封内的人民币,大家轮流看一看、摸一摸,你能发现什么呢?观察时小朋友们要互相谦让,有礼貌。
2.师:你都发现了什么,谁愿意说给同学们听一听?(主要引导学生从人民币的数字、面额、字样和各种图案说一说。)
3.个别发言,出示教材第68页“认一认”。
【这一步主要是让学生认识人民币,通过让学生亲自去看、摸,使学生对人民币有初步的了解,同时,凸现学生的个性思维及创造思维,培养学生独立获取知识的能力】
师:刚才,我们认识了人民币,现在我们就一起去买东西,看你会不会买?(以小组为单位,开展购物活动。)
1.小组合作:组长来当售货员,其他同学用课前准备好的人民币(课本后的彩图)购买自己想买的文具。
2.师:同学们的收获都不小,你能从你买的文具中选一种介绍一下你是怎么买的吗?(指名说一次购物过程。)
3.师:小朋友们,你们看,我这里有1张1元钱,我也想去买一些文具,你们愿意帮我去买吗?下面就请同学们用1元钱去买文具,你能买些什么呢?(小组继续购物。)
4.反馈,并板书:
1元
2角找回8角
1角找回9角
买文具 教师说课,标签:一年级数学说课稿,小学数学说课稿,
……
运用课件演示元和角之间的关系,以及角和分之间的关系,并板书:
1元=10角
师:现在我们知道了1元=10角,也知道1元钱能买哪些文具,你能独立完成第69页这些题吗?(学生独立试做。)
5.师:大家都完成了,现在谁愿意把你的展示给大家看一看。(实物投影反馈。)
6.师:在你的生活中,1元钱还可以买哪些物品呢?(同桌交流。)
【通过购物让学生初步理解人民币的功能,掌握元、角、分之间的关系,同时,让学生体会到数学与生活的密切联系。】
四、解决简单问题。
1.请学生来当售货员,老师拿一张5元的人民币去买一支钢笔,售货员没有零钱找给老师,由此创设一个需要兑换人民币的情境,然后让售货员自己去想办法。
【让学生体会到兑换的必要性。】
2.师:你在平时的生活中遇到过这样的事情吗?你现在想不想让同学们帮你去解决呢?你可以找一位好朋友去兑换。
3.师:哪一对好朋友想把你们的收获告诉大家。(全班交流,并板书,用实物粘贴。)
5元 能换5张1元
2元 能换2张1元
5角 能换5张1角
……
4.独立完成教材第69页“填一填”第1题。
5.师:谁想把你做的展示给全班同学看。(实物投影反馈。)
【通过情境让学生体会到人民币之间可以兑换,也让他们体会到在日常生活中遇到此类问题应如何解决,加强数学与日常生活的联系。】
2元=( )角 30角=( )元
4元=( )角 50角=( )元
3角+6角=( )角2元+2元+1元=( )元
师:人民币是我们平时生活中离不开的,在勤俭节约方面,爱护人民币方面,你是怎么做的?说给你身边的小朋友听。
访问或调查并记录:你对人民币还知道些什么?
【培养学生搜集信息的能力。】
评析
本节课学生是在购物情境中完成的,学生对情境非常感兴趣,本节课的任务也完成了,但是学生对人民币的感知还不够,在学生独立观察人民币后,让学生说一说时,教师的指导还不到位,学生说不出来的一些方面,教师应引导学生说出来,比如人民币上的数字是什么意思,人民币上的图案都有什么,等等。接下来的购物活动不仅激发了学生的参与意识,而且在活动中自然而然地认识了人民币及元、角、分之间的相互关系,理解了人民币的功能,还培养了学生正确的数学学习方式,将数学教学变成了数学活动的教学。

一年级数学说课稿上册篇三
一、说教材
《认识钟表》是人教版义务教育教科书一年级上册第七单元的内容,本课的教学是学生在小学阶段第一次接触时间学习,是在学生已经积累了大量看钟表时间的经验基础上进行教学的,又是二年级进一步学习半时的认识和三年级秒的认识的开始,掌握认识钟表和整时是小学生必备的知识。教学的本质在于帮助、激励、引导,本课就是在学生已有经验的基础上,注重联系实际,力争做到“思想、方法、知识、能力”的有机统一。根据教材的地位确定如下教学目标:
1.通过动手操作使学生初步认识钟面,知道时针、分针及钟面上的数字;并使学生结合生活经验学会看整时,知道整时的两种表示方法。
2.通过观察、操作、交流等活动,发展学生的数学思考能力,培养学生的探究意识和合作学习意识,体验学习数学的兴趣。
3.使学生初步建立时间观念,自觉养成了遵守和珍惜时间、合理安排时间的良好习惯。
这样的目标设计使我更多的关注学生在有限的时间让学生获得更多的发展。根据本课教学内容的特点确定教学重点为整时的认读方法。教学难点为学生初步建立时间观念,会看钟表上的时间。课前准备了教学课件、钟面模型、钟面模型零件等大量教具。
二、说教法
教师是数学活动的合作者、引导者和组织者,为了突出重点、突破难点,结合一年级学生的认知规律,遵循教师为主导、学生为主体、训练为主线的思想,本课主要采用启发式教学和探究式教学相结合的方式进行教学。在学生初步感知钟面特点的环节主要采用启发的方法,引导学生发现钟面上都有些什么,逐步归纳、总结,从而使学生形成表象认知。在例题学习环节主要采用探究式教学法,引导学生自己观察、对比、讨论出钟面上的三个时刻有什么共同点和不同点,从而探究认读整时的方法。
三、说学法
《新课标》指出:有效的数学活动不是单纯的记忆和模仿,自主探索、合作交流是学习数学的重要方式。基于这样的理念,本课学生的学习方法主要有独立思考、合作交流、动手操作等。让学生初步认识钟面后,我为了加深学生对钟面的进一步认识,设计了学生自己制作钟面的活动,在这一活动中充分锻炼了学生的动手操作能力,在操作遇到困难的时候学生自然而然的想到了自己的同伴,小组合作的学习方式会给学生的学习带来最大的帮助。
四、说流程
1、上课伊始,我就抓住学生好奇心强、求知欲旺的心理特点,创设情景猜谜语,为后期学习创设了一个良好的学习开端。通过回忆“在哪里见过钟表”充分唤起学生的已有经验,结合生活实际进行教学。
2、自主合作、探究新知是课堂教学的重要环节,也是学生掌握知识、培养能力的主要途径。根据学生的接受能力,我采用讲练结合的方式,帮助学生理解新知。设计了三个层次,首先让学生观察钟面,充分交流,全班汇报,了解钟面上有什么,从而形成表象,再通过动手制作钟面加深对钟面的了解;其次,让学生通过对三个时刻的对比,找出相同点和不同点,从而归纳出认读整时的具体方法;最后,为了锻炼学生的动手操作能力,进一步巩固认读整时的方法,安排了学生动手拨时钟的练习。
3、巩固练习、运用新知也是课堂教学的重要组成部分,不仅有助于学生巩固新知,还可以让学生合理灵活的选择新知解决实际问题。安排了本课的基础练习课本86页练习的第一题连线,和提高练习课本85页的做一做,最后让学生体会接近整时的“快8时”和“10时多一点”的发散练习。层层递进,使每一位学生都有所发展。
4、总结评价、回顾新知,通过“你有什么收获”这样的问题,引导学生系统回顾,明确本课的知识重点和学习时应注意的问题和方法,帮助学生更深刻的理解知识。
我注重系统直观的板书,及时的体现了知识点,便于学生对新知识进行梳理。
总之,一节课的成功与否不仅是课前教师设计的好,还要及时抓住课堂的生成问题,巧妙处理,这样才能真正让学生在我们的课堂上有所收获。

一年级数学说课稿上册篇八
《数学课程标准》明确指出:“学生是数学学习的主人,教师是数学学习的组织者、引导者和合作者。”基于对《数学课程标准》的研读,结合本节课学生的年龄特点及认知水平,我对本节课的教学理念有如下认识:
1、创造有利于学生理解的教学情境,让学生在现实情境中体验和理解数学,经历数学化的过程。
2、为学生提供充分数学活动的机会,变“学数学”为“做数学”。
3、让学生经历知识的形成过程,感受推理、转化等数学思想方法。
4、多方位、多元化评价学生。
在教学过程中坚持“以学生为主体,以教师为主导”的原则,依据学生的心理发展规律,采用学生参与程度高的教学方法即,教师的“教”立足于学生的“学”。
1、教学内容 人民教育出版社九年义务教育课程标准《数学》教科书一年级下册第61页主题图及第62页例1,完成“做一做”及第63页练习十四第2题、第3题、第5题。
2、教材分析 本节课内容是在学生基本掌握了100以内数的`读法、写法和数的组成,以及整十加一位数和相应的减法的基础上进行编排的。整十数加、减整十数的口算方法与10以内加、减法基本相同,只是计数单位不同,是以十为计数单位。教材首先呈现给学生的是一幅发新书的情境图,学生尝试提出数学问题。小精灵的提示语显示出让学生自主探索口算方法,相互交流,体现了算法多样化理念。这样编排,有助于学生加深对相同单位的数可以直接相加、减的认识,为后面学习任意两个数相加、减打基础。整十数加、减整十数属于本单元教学中的重点内容之一,着重解决把相同数位的数相加。遵循了由具体到抽象的原则,有利于学生思维能力的培养,为进一步提高计算速度、培养计算能力,解决实际问题打基础。
3、教学目标 根据《课程标准》的要求,结合教材的特点及学生的实际情况,我制定了以下三个目标:
(1)、经历在实际情景中提出问题并解决问题的过程,掌握整十数加、减整十数口算的方法,并能正确计算。
(2)、让学生学会把整十数加减整十数归结为10以内加减法,树立转化意识。
(3)、在观察、比较、合作交流中逐步培养学生主动探索和独立思考的意识,感受算法的多样性,培养思维的灵活性。
(4)、体验解决问题的成功喜悦,树立学好数学的信心。
4、教学重难点 教学重点:整十数加减整十数的口算方法。教学难点:整十数加减整十数的口算的算理、算法。
本着树立以“以学生发展为本”、“以学定教”、“教为学服务”的思想,在教学活动中我采用引导自学、合作交流相结合的方法,让学生在理解算理的基础上熟练运用算法形成计算技能,有效地提高了教学效率。在知识的应用阶段,我还采用自主探索来解决问题,形成技能。
因为计算常给人的感觉是枯燥乏味,所以在教学中我借助发新书这一生动情境,把整十数加减整十数的口算置入有事物情境、有情节的探索中,使口算含有丰富、生动的具体内容。
在探索整十数加减整十数的口算方法时,通过讨论、交流、动手操作等活动,让学生自主探索,显示不同算法,体现了《课标》中“鼓励学生独立思考,提倡计算方法的多样化”的理念。
练习环节请学生帮忙摆筷子,参与开火车游戏,帮助家人买衣服,淡化“练”的痕迹,巩固和实践相关的知识技能,发展数学思考能力。
这一节课的教学对象是一年级的学生。他们年龄小、好动、爱玩、好奇心强,在四十分钟的教学中容易疲劳,注意力容易分散。根据这一特点,为了抓住他们的兴趣,激发他们的好奇心,我借助发新书的情境,让学生在身临其境的环境中愉快地学习。《课程标准》指出:“动手实践、自主探索、合作交流是学生学习数学的重要方式”。在教学过程中,通过让学生看一看(看图)、想一想(想问题和算法)、数一数(数书)、说一说(说算理与算法)、摆一摆(摆小棒)等多种形式,让学生积极动眼、动耳、动脑、动口,引导学生通过自己的学习体验来学习新知,积极开展本节课的数学活动。充分体现了学生为主体教师为主导的原则。体现了《课程标准》要求“学生是学习数学的主人,教师是数学学习的组织者、引导者和合作者”的功能。
