一年级数学说课稿上册篇二
《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
今天我讲的课题是《小猫吃鱼》
首先，我对本节教材进行一些分析
北师大版小学数学一年级上册第28---29页“小猫吃鱼”。
材料中安排的“小猫吃鱼”是一组动态的连续故事情景，通过这一故事情景，让学生进一步理解减法的意义。同时也通过一组动态情景，逐步引出得数是零的减法算式。由于减法的意义对于一年级学生而言，是比较抽象的，如何把这个抽象的概念变为学生能够体会的食物呢？这就需要我们教师来创造性地使用教材，结合本班的实际情况灵活把握。
一年级学生的动手能力较强，生活经验也较丰富，对“小猫吃鱼”.“小鸡吃食”.“吹泡泡”等有自身的经验。利用这些具体情境有利于激发学生的学习兴趣，使他们体会数学与生活的联系。
1. 在具体的情境中进一步巩固对减法的认识。
2. 理解得数是0的减法算式的实际意义，并能正确计算5以内数的加减法。
3. 初步体验加减法呼你关系的思想。
4. 通过合作交流，获得成功的体验；培养学生认真观察.积极思考.勇于探索的精神。
进一步体会减法的含义。
1. 根据本节课的意图主题图特点，我采用了以下教法
充分发挥学生的主体性，让学生通过课堂游戏.互相合作、实际操作等方式，自主探索，是学生在游戏的过程中不知不觉的学会知识。
2. 通过本节课的教学，是学生掌握一些基本的学法
让学生学会自主发现问题，分析问题，解决问题的方法。
让学生亲生经历生活中的数学问题，并参与解决问题的过程，激发学生学习的积极性，向学生提供充分从事数学活动的机会，让他们积极主动的参与.解决数学问题。所以本课在教学思路上淡化教师教的痕迹，突出学生学的过程。从而充分体现了学生是学习的主人，教师知识学生学习的组织者.引导者与合作者。
（一）创设情境，激发兴趣。
由于学生熟悉和喜欢的“过生日”的场面引入，激发学生的学习兴趣。将原课题“小猫吃鱼”改为“小猫过生日”，体现了以活动为主线进行教学。
（二）细看画面，展开想象
告诉学生今天是小猫的生日，猫妈妈特意为它准备了最爱吃的小鱼。然后提问: 1. 数一数，盘子里有几条鱼？
2. 看着小鱼，小猫心里会怎么想呢? 3. 猜一猜，小猫会吃掉几条小鱼？
设计意图：一数一猜一想，注重培养学生的想象力.思维能力和语言表达能力，体现了以人为本的思想。
（三）套圈游戏
教师引导为了给小猫生日助兴，小方已经迫不及待的表演套圈了，认真看图，你能根据图和所给的加法算式，列一道减法算式码？
设计意图：让学生在欣赏表演中学习，即可是学生放松身心，又可获得知识。
（四）吹泡泡游戏
引导：小朋友，你们玩过“吹泡泡”的游戏吗？下面小明要给小猫表演吹泡泡了，认真观察图画，思考，互相交流。
设计意图：让学生在自己亲身经历过的游戏中学习，培养学生认真观察和积极思考的精神，初步理解“0”在减法中的意义，从而是学生知道生活中处处有数学。
（五）摆学具游戏
同学们，你们看小方和小明都给小猫表演了自己精心准备的节目，我们是不是也应该表示表示呀？听老师的口令……..
设计意图：结合学习内容，设计学生喜欢的摆小棒实践活动，既可以是学生放松身心，又可以获得知识，进一步理解得数是0的减法算式的实际意义。
（六）分蛋糕，学会合作
小猫要请大家吃蛋糕了，小朋友们高兴吗？
请出5个小朋友，其中一个演小猫，请大家吃蛋糕。
设计意图：结合学生的生活体验，设计吃蛋糕这一环节，让学生感知数学就在自己身边，通过小组活动，给学生提供了充分的合作与交流的机会。
（七）总结
回想这节课，我们都玩了哪些游戏，通过这些游戏你有哪些收获？学生谈收获。
（八）联系国庆，体验快乐
明天就是10月1日了你知道10月1日是谁的生日吗？
设计意图：由小猫的生日自然过渡到为祖国妈妈祝贺生日，培养学生热爱祖国的情感。
（九）布置作业
课本第29页第一题和第二题
以上，是我从说教材，说学情，说教法，说学法，说教学程序上说明了“叫什么”和“怎么教”，阐明了“为什么这样教”。并希望各位老师对本堂说课提出宝贵意见。
一年级数学说课稿上册篇四
在解构——建构过程中认识百数表
《百数表》这个教学内容安排在一年级学生刚刚认识百以内数的组成，会读、会写百以内数的基础上，这是教材中第一次把100以内的数全部展示在学生面前。学生在刚刚认识数时所认识的数是“独立的”，而对数之间关联的意识直接影响到孩子们选择解决问题的策略，因此需要教师适时的帮助学生构建数与数之间的关系。百数表正是这样的好材料，因此想充分挖掘百数表中的规律，引导孩子感受数之间的关系。
由于数较多，《百数表》里面呈现的很多规律不利于学生发现，因此在认识百数表时必须经历一个给百数表解构的过程。同时，100个数有规律的排列在一起，已经成为数的系统，初步显现了十进位值制数系统的一些特性，因此又需要我们对其中的数朋友进行归纳、整理，构建数之间的关系，以使学生对百以内的数有整体的认识，这就要引领学生经历建构的过程。也正是在不断地解构与建构的过程中，学生对数的认识才能得以深化。
一、在解构的过程中，培养学生数感
（一）解构百数表，发现数的排列规律
由于百数表有顺序的把数展示出来，数在排列的过程中就呈现出很多的规律，而这些规律的呈现又是很多规律交叉进行，不利于学生观察与发现，因此在教学中以按顺序出现数队伍的方式解构百数表：横行、竖行、斜行，引导孩子们通过比较每一队中的数朋友，发现数的十位与个位上的变化是与数所在的位置有关系，位置排列的有规律，数的排列也有规律。通过探寻为什么从而深化学生对数位、计数单位的认识，感受数的神奇。
（二）解构百数表，深入认识数
没有点的深入就没有面的提高，没有对百以内个别数的深入认识就没有对百以内数的整体认识的提高。通过对个别数的深入研究，把握相同的质，帮助学生对百以内的数有新的认识。由于不同的数在表中都有各自的位置，因此从位置入手来研究数，可以帮助学生形成新的认识，本节课中给“35”找家时，提供了百数表中的第一行和第一列，实际上就为学生提供了坐标轴，让学生根据数的意义去找位置，渗透了坐标的思想，深化了对数的认识。
（三）解构百数表，深度把握概念
100个数聚集在一起，有很多数具有相同的特性，出现了相应的数学概念：单数、双数、一位数、两位数、三位数。在教学中孩子们对数位、位数等概念非常易混，对单数和双数只是一种浅显的认识，还没有把握其根本的特点，因此本节课中利用给数照相的环节，通过分类的方式解构百数表，“分类活动的一个重要作用，既是为相应的数学抽象提供必要的基础。”因此学生概括得很简洁：个位上是1、3、5、7、9的数是单数……他们把握了这些概念的特征。
解构有分析的意思，解构百数表，目的在于排除干扰，深入对个体的把握，从而深度认识百以内的数。
二、在建构的过程中，培养学生数感
百以内的数是数系统中的一部分，是一个小的系统，因此只解构是不够的，还要带领学生不断地去建构，帮助学生对这个小系统乃至大的数系统有整体的把握。
（一）在找位置的过程中，建构数之间的关系
每一个数都是一个独立的个体，同时也是数系统当中的一员，它们之间有着非常广泛的联系，而儿童“所知道的的数是孤立的，就像在学会说流利的句子之前所学的生词一样。”这也正是孩子们数感弱的原因。百数表“不仅呈现个别数，而且为说明数在逻辑结构中的联系方式提供了丰富的图形。”2因此本节课通过为数找家的环节，引导学生通过为数找位置构建数与数之间的关系，感受关系的多样，从而培养学生“数之间有关联的意识”，2进而培养学生的数感。
（二）在指挥数站队的过程中，感受数的无限
在学生已经构建了数之间关系的基础上，应该引导学生感受十进位值制数系统的一些特性，进一步加强整体感知，因此在课的最后，通过指挥数排队把百数表变形为数轴，在数轴上进一步感受数之间的相对大小关系，感受两数相差得越多，离得越远，相差越少，离得越近，从而形象化的感知数之间的相对大小关系，同时通过数站队永远站不完来形象的感受数的无限。
这样对百数表不断地进行解构使得学生所获得的知识是深入的、不是肤浅的；帮助学生不断地建构，使得他们所认识的百以内的数是结构化的、整合的，不是零碎的、只言片语的。通过解构，深化认识，通过建构，整体把握。
这节课一直在和数做游戏，课中赋予数人的特性，淘气、可爱、有灵性，同时又需要帮助，以激发学生对数的情感，使学生感受数的可爱、感受百数表的神奇，有了这样的基础，学生上数学课就成了享受。
一、引入
师：百数表中来了几队数朋友，你知道每一队缺了哪些数？说说为什么？
师：如果老师请你在百数表里找十位是8的数，你到哪儿去找？
师：如果老师请你找个位是8的，你到哪儿找？
师：这些数里都有8，8表示的意思一样吗？
师：表示的意思不一样，它们的位置也不一样。
二、研究与讨论
（一）引导学生在给数找家的过程中感受数之间是有关系的
1.根据提供的一行一列为数找家，渗透坐标思想。
2．区分不同数位的意义。
师：你看它们都想住在这个格子里，你觉得谁应该住？（学生讨论）
3．根据百数表中无序排列的数，为数朋友找家，构建数与数之间的关系。
师：原来的这些数朋友说我们也要出去玩了，这次你还能帮它们找家吗？
（二）根据数所在的位置猜数
1．根据位置来猜数，培养学生灵活解决问题的能力。
师：这些数朋友们也出去玩了，你还能为数朋友找家吗？
这个时候有一个数悄悄地来了。
师：它找到自己的家了，你知道这个数是多少吗？怎么想的？
2.为照片上的数找家，教给学生方法。
师：这个时候又回来了一位数朋友，你们想知道它是谁吗？
生：想。
师：这次请一位神奇的摄影师来告诉你们，他正在给百数表照相，正好照到了这个数，它是谁？
师：这张照片上还有哪些数朋友藏起来了？
师：为了奖励大家，摄影师说了，我们再照两张，想看看照片吗？
生：想。
师：这个照片可与众不同，缺不缺数朋友？快来把这些数朋友找出来。
（三）通过分类活动，对百以内的知识点进行整理，升华学生的已有认知
1.按单双数分类，深化学生对单双数的认识。
师：这些数朋友说摄像师要给我们照相，我们都回来了。
出示百数表：
师：这个时候摄影师说，太多了，你们得变个队形我才能给你们照，你们能帮它们变队形吗？你们只要喊一二变，他们马上就变，准备好了吗？
生：一二变。
动画
师：站成了两队，它们站得有道理吗？什么样的数是单数呢？
2.按位数分类，明确一位数、两位数、三位数的概念。
师：这时候摄影师说了，1~9出列，100出列，我要分别给你们照一张。
师：你们明白摄影师的心思吗？摄影师是怎么想的？
3.从百数表变化成数轴，引导学生感受数的无限。
（1）通过整十数变队形，感受数的无限性以及等距性。
师：现在有一列数朋友说它们要单独照一张，是谁呢？
师：因为这条线没完没了，怎么办？用箭头表示：一直排下去吧。
师：现在我们为这些数都找到家了。你们看，从10到20，从20到30，从30到40，它们之间的距离怎么样？
生：都一样。
师：为什么它们之间距离就一样长？
生：因为他们的十位是1、2、3、4、5、6、7、8的，一个比一个多10。
师：都多10，所以它们距离就是一样的。那如果是这样的话，请问10前面的这个家是谁的？
生：0。（课件补充0）
（2）通过给数找家的游戏，进一步渗透两数的大小以及相对位置之间的关系。
师：这个时候又跑来了一行数朋友，咱们读读。
师：你们说它们的家在哪儿？
师：小于60的数朋友住在哪儿？
师：这些数朋友的家离60的家一样近吗？
一年级数学说课稿上册篇五
这一课是学习20以内退位减法的起始课，是在学生掌握了20以内的进位加，以及10以内加减法基础上进行学习的，为今后学生学习100以内数的加减法做好铺垫。使学生通过本课学习鼓励学生独立思考、大胆尝试，从而对数学的本质产生新的领悟。
知识与技能：能正确计算十几减9、减8的减法，并能简单应用。
过程与方法：运用已有的生活经验和知识，探索十几减9、减8的退位减法。
情感态度与价值：培养善于思考、倾听的学习习惯，能理解他人的不同算法。
1、 学会正确计算十几减9、十几减8的退位减法。
2、 理解多样化的计算方法中的一种或几种。
感知计算方法的多样性。
教学过程共分为以下三个环节：
第一环节：创设情境，激发兴趣。（网络）
第二环节：探索算法，解决问题。（多媒体）
第三环节：拓展活动，综合训练。（多媒体、网络）
首先，我创设情境：“小朋友都喜欢做游戏吗？这节课我们就一起来玩一个打靶飞镖的游戏。”根据学生打出飞镖的数量提出数学问题“这节课我们就先来解决15-9= 这一问题。”由此导入新课在这里我改变教学情景，把教材提供的主题图小白兔到袋鼠的文具店买铅笔的情景，设计成学生熟悉而又感兴趣的打靶飞镖游戏，把游戏搬到课堂上，让孩子亲身参与，真切地感受数学与现实生活的密切联系，最终这一情景设计的改变在教学反实践中达到了课堂气氛更为热烈突出的教学效果。
这一环节探索十几减9、减8的计算方法是本节课的教学重点
1、独立思考15-9的算法：学生经过独立思考，去整理自己的思路，才能在后一环节小组交流中充分发表自己的见解
2、小组交流：这一环节根据借助网络的教学探讨让小组合作具体化，组内交流不流于形式，完成教学目标培养善于思考、倾听的学习习惯，能理解他人的不同算法。因此我在让学生把准备好的算法依次说给组里的小朋友听的时候，提出了具体要求，交流时注意：（1）说的小朋友尽量说清楚，让每个人都听懂你说的意思（2）注意倾听别人的发言，说过的方法就不要重复等
3、全班汇报：引导学生在听与说、议与思的互动过程中，寻找合理，简便的.算法来培养优化的意识，利用多媒体展示本课的四种重点方法，在对于是非辨别能力较弱的一年级学生给他一个思考的空间但做出正确的引导，即体现教师主导又让学生主体作用得以发挥，最终形成学生对“20以内退位减法”的深刻理解。
4、学生选择自己喜欢的方法尝试练习15-8＝?
这一环节，是以一个小兔把萝卜的故事贯穿始终通过“小兔背萝卜” “送小兔回家” 一系列的故事发生发展过程中进行（17-9）的基本应用训练、拓展思维训练等。
既充分发挥了孩子们的创造力，想象力，又让他们在充满生机与乐趣的氛围中，展开想象的翅膀，感受学习的乐趣。
教学媒体设计思路：
多媒体整合点：利用多媒体创设符合学生认知心理的情境，一环接一环的故事，好像一集集的动画片吸引着学生.充分发挥教师主导及学生的主体地位，让学生轻松理解新知。
网络整合点：我请了几位教学资深的领导、老师来帮助我审核这堂课，但由于地域、以及平时班主任工作的繁忙我们真的很难有时间聚在一起讨论，这确实让我感到棘手，后来我利用了我们和平区教师博客进行交流研讨，在这里我发表了我的教学设计，很快得到了更多老师的回复点评，这样棘手的问题几乎不成问题，而且也让更多的老师参与进来，后来我经过三次试教，多次网上研讨，多方面改进，终于今天承载着众多老师的智慧走到了全国大赛。
有效地进行了信息技术与常态教学的整合：本课我选择的不是网络运用自如，很有网络发挥空间的特殊课例，而是一堂普普通通再常态不过的计算教学课，而它所体现的整合作用却让我受益匪浅，使我对新课标的理念和信息技术与课程整合有了全新的认识，极大地提高了我的教学视野。
在此感谢组委会给我这样一个机会。谢谢各位评委老师。我的说课就到这里。
一年级数学说课稿上册篇六
教材分析：
教学内容：义务教育课程实验教科书北师大版数学一年级上册第五单元“位 置与顺序”第二课时：上下。
教材简析： 在新课程标准中，有明确指出各个学段发展学生空间观念的具体目标。本单 元是通过在具体的活动中，让学生体验前后、上下、左右的位置与顺序，从而初 步培养学生的空间观念，属于培养学生空间观念的第一学段。本节内容“上下” 是学生学完“前后”的位置与顺序学习的，继续培养学生按一定的顺序观察、描 述事物的好习惯，学会用上下正确描述物体的位置关系，进而初步发展学生的空 间观念，为以后的发展打下扎实的基础。
教学目标、重点、难点：
《标准》中对数学课程的总体目标具体化为四个方面：知识与技能、数学思 考、解决问题、情感与态度。根据以上四点，结合本节课的实际，我制定以下的 教学目标。
（1）在具体的活动中，让学生体验上下的位置与顺序，体验上、下位置关 系的相对性，并能用自己的语言表达。（知识技能目标）
（2）初步发展学生的空间观念，培养学生简单的空间推理能力。（能力培 养目标）
（3）初步培养学生按一定顺序进行观察的习惯。（素质培养目标）
（4）在活动中引导学生进行比较、推理等思考活动，让学生感觉到数学就在身边，学习数学是有趣的，以获得良好的情感体验。（情感态度目标）
教学重点：学会确定物体上、下的位置与顺序。
教学难点：体会上下位置关系的相对性。
说教法与学法设计：
本节课要让学生在具体活动的过程中获得相关体验，不能把它作为单纯的知 识点来讲授，而要在已有经验的基础上让学生获得体验和理解。结合一年级学生 活泼好动、求知欲强和本节课学习素材的特点，实现转变教学方式和学生的学习 方式，体现学生为主体，教师为主导的教学原则，我设计了以下的教法和学法， 既重视选择灵活的教法，又注重对学生学法的指导。
创设情境，直观形象法。
创设小动物去大树爷爷家做客这一情境，引导学生 观察主题画，让学生能直观地明确三种动物的位置关系，体验到上下的位置关系， 并创设三种动物变换位置关系的情境理解上下位置关系的相对性。
观察讨论，互动合作法。
新课标特别提倡自主、探究、合作、实践的学习方式，要求引导学生主动参 与，亲身实践，独立思考，合作探究。堂上引导学生观察讨论，说说教室的物品 的位置关系，紧扣学生的生活经验开展教学，引导学生通过互动合作给动物分房 子等活动，进一步理解上下的位置关系，培养学生应用知识的能力，增强合作意 动手操作，积极活动法。通过老师下口令，学生摆物品、整理书架、给动物分房子等活动，让学生动手、动口、动脑等多种感官去加深理解“上下”的位置 关系，及理解其位置的相对性，初步发展学生的空间观念，培养学生的应用意识。
教具准备：主题画、投影仪、小书架
学具准备：剪刀、胶水
说教学过程：
第一环节：创设情境，激趣引疑。
为了吸引学生的注意力，调动学生的学习兴趣，我创设了这一情境导入新课： 今天，天气晴朗，森林里特别热闹，原来大树爷爷今天请客，小兔和小鸟一大早 就到了（出示主题画，先出示小兔和小鸟）让学生观察直观到小鸟和小兔的位置 不一样，我顺势引出课题：“上下”。通过设疑引出课题，能让学生有发现问题 的机会。
第二环节：观察思考，探究新知。
观察思考。先引导学生观察主题画，仔细观察小鸟和小兔的位置，让学生自 由说说小鸟在小兔的哪个位置上，小兔在小鸟的哪个位置上，让学生初步理解上 下的位置关系。
1、理解上下位置的相对性。
引入松鼠，思考：松鼠站在哪？让学生体验由于参照物不同，上、下位置关 系是相对的。我注意使用浅显生动的语言向学生说明小动物位置关系的相对性， 再让学生描述松鼠的正确位置，从而体会上下位置的相对性。 （由于理解上下的位置关系与相对性是本节课的重点和难点。这时教师要发 挥引导作用，有必要作出适当的说明，对学生理解新知很有帮助。）
2、换换位置，加深理解上下的相对性。
让学生动手换一换小鸟和松鼠的位置，要求学生互相说说三种动物各自的位 置关系。（学生能在变化中进一步体验上、下位置关系的相对性，学会举一反三， 培养他们思维的灵活性。） 指导看书，书写。 指导学生根据判断的三种动物的相对位置，填写好书本的内容，注意上下的书写，培养学生正确书写的习惯。
第三环节：应用新知，解决问题。
这一环节，我设计了一系列的活动，让学生学会应用新知去解决问题。
3、联系身边的例子说一说。
观察教室，讨论哪些物体的位置关系可以用“上下”来描述。学生自由观察， 自由发表意见。（设计意图：联系学生身边的例子来应用新知，使学生感受到数 学就在身边，学习数学是有趣的，以获得良好的情感体验。） 听口令，摆物品。要求每人准备好数学书，练习本，文具盒和铅笔等学习用 品。老师下口令，学生摆物品，可以设计以下口令：数学书放在桌面上，文具盒 放在数学书的上面，练习本放在数学书的下面等等。（因地制宜地组织教学，可 以帮助学生更深刻地理解知识。） 整理书架。每个小组一个小书架，一些书和其他学习用品。要求：小组内互 相商量如何摆放这些物品，然后动手一起摆一摆，在摆的过程中说出物品的上下 位置关系。以小组合作的形式开展活动，培养学生实践的能力和合作交流意识。
4、参观小明的房间。
（课本练一练第1 先引导学生说一说看到了什么？组织学生讨论交流，再根据自己观察到的，把各种物品的上下关系补充完整，培养学生解决问题的能力，借助这一情境，要 求学生回去整理自己的房间，养成物品摆放整齐的良好行为习惯。
（以上活动是根据课程标准中指出数学教学活动必须建立在学生的认知发展 水平和已有的知识经验基础之上设计的。）
5、巩固练习，内化新知。
题。注意引导学生读题，理解题意，在写数过程中，让学生说说哪个数在上，哪个数在下。 课本第59 题：说一说。利用图画组织学生讨论，引导学生互相交流自己的想法。这是一道有一定开 放性的题目，有多种的说法和答案，如船在桥的下面，人在桥的上面，桥在船的 上面等。主要是培养学生的发散性思维和应用知识的能力，进一步发展空间观念。
第四环节：动手操作，合作交流。
（完成第59 活动要求：先引导学生弄懂题意，然后指导学生剪下附页中的动物头像，按照自己的意愿给小动物安排房子。 活动形式：学生可以在小组中合作完成，分完后，与小组同学交流是如何安 排的，说一说它们的上下位置关系与顺序。这样做培养学生动手操作和解决问题 的能力，同时增强交流合作的意识。
第五环节：拓展思维，强化新知。
（第59 这是一道有一定难度的题目，不做统一的要求。目的是培养学生简单的空间推理能力。对不同水平的学生可以提出不同的要求。在反馈的过程中，适当引导 学生有条理说出自己的推理过程。
第六环节：总结深化，自我评价。
结合新课标里提出新的评价体系，我在这一个环节设计了一张表格，让学生 对自己这节课的表现做个评价，每人一张评价表，在认为自己做得好的那格画上 一个笑脸。
对学习数学有兴趣 积极参与小组的讨论交流 能积极大胆地发表自己的意见乐意倾听其他小朋友的意见 通过以上六个环节的教学，我认为能发挥学生的主体作用，学生乐意学习，主动 参与数学活动，学生的空间观念得到初步培养，能达到预期的目标。
