第五单元时分秒的认识教案

第五单元时分秒的认识教案 第五单元 时、分、秒 一、教学内容 1(时间单位“秒”的认识 2(对于一段时间的感受和体验 3(简单的时间计算 二、教学目标 1(认识时间单位“秒”，知道1分=60秒。 2(会进行一些时间的简单计算。 3(初步建立时、分、秒的时间观念，养成遵守和爱惜时间的意识和习惯。 三、编排特点 1(结合学生的生活实际帮助学生认识抽象的时间概念。 主题图中新年联欢晚会的倒计时。 商场内钟表柜台的场景。 上学路上花费时间的计算。 学生的作息时间。 商场开门、关门时间。 火车晚点。 调查50米跑花的时间等。 2(借助活动让学生体验一段时间，建立正确的时间观念。 体验1分钟有多长，1分钟能做什么，刷牙、整理书包等需要多少时间。和所有计量单位一样，除了重视单位的换算及相关计算以外，要更强调“观念”的建立。 (注意让学生收集有关时间的信息，培养学生的实践能力。 3 如:练习十四第3题，第7题。 四、具体分析 (一)秒的认识 1(主题图 结合学生熟悉的新年联欢晚会的场景，使学生直观认识生活中“秒”的存在。教学时可以用录像的形式让学生看一下这个场景，也可以让学生回忆一下每天新闻联播前面也有这样的倒计时，还可以拿一个钟让学生听一下“滴答声”，初步感受1秒的长短。 2(秒的认识和“1分=60秒” (1)教材直接说明要用“秒”来计量很短的时间，然后提出问题“怎样计量,”引出钟表上的秒针。教材上呈现了商场里钟表柜台的情景，图中的大部分钟表上都有秒针，使学生直观认识一下。 (2)接下来，学生利用不同的计时工具来进一步认识秒，并探索1分=60秒的关系。在这儿，有机械钟表，有电子钟表，还有秒表。学生通过自主探索，发现机械钟表上有三根针，秒针走得最快，秒针走1小格是1秒，秒针走1圈(60格)时分针走1格，所以1分=60秒。在读取电子表上的时间时，学生可以利用以前学过的电子表的读取方法进一步类推。由于学生已经有了很多关于钟表方面的经验和知识，这个活动可以放手让学生自己去完成。可以让学生思考这样的问题“为什么秒针走得最快，时针走得最慢,” 3(P61“做一做”(感受时间的长短) undertaking, strengthen the construction of party and Government personnel. To vigorously implement the "capacity building" project, solution engineering immigrants safe haven and other key projects, key projects as the main capacity-building and their own business, Act big, good, capable to do difficult things, high standards and a high level, and constantly enhancing the development of leadership capacity. Focusing on precision of poverty, strengthen the construction of practical personnel in rural areas. Around the development of practice, a village if there are several talents cultivation, processing, marketing, can promote the development of the village, village of JI Zhen an Peng is a People driving a village, Sun Qingyuan back in business as branch Secretary, Ann village has changed dramatically. County Social Welfare Bureau, agriculture Bureau, the Immigration Department (unit) will increase its training of rural talents, pay attention to the strong desire to learn, cultural foundation of "local people" skills training, role play capable drive getting rich, focused on creating a support national policy, Fu Fu and strong talent. With the development of urbanization, especially promotion of hedging relief project, communities of immigrants have been staying, need more community management personnel. The relevant town (Street) to co-ordinate focus on Community Affairs, Social Affairs, public service, protection of migrant people into community, sharing the good life. Laohuzhen Qian BU Zi Cun Jie Qingli, after participating in the e-business training courses throughout the County using learned knowledge of electrical contractor, registered the "Chen of Dongping Lake fish produce" shop, forming a home order online order business model 时间是一个很抽象的概念，所以要借助于活动帮助学生建立正确的时间观念。一年级认识的基本上都是时刻，在这儿逐渐渗透时间段的知识，为下面教学时间的计算做准备。 第1题，让学生通过读秒来体验1分钟的长短。一方面可以建立1分钟的长度观念，另一方面，可以更加直观地看到1分=60秒的关系。 第2题，1分钟能做什么，教材中列举了四个平时学生生活中1分钟活动的例子，并鼓励学生举出更多的例子来，如1分钟能从哪儿走到哪儿，1分钟能拍多少下皮球，游泳能游多远，等等。通过这些学生自己生活中的例子，能更真切地体验1分钟的长度。1秒比较短，学生不太好举出这方面的例子，可以让他们用语言来描述一下，模仿着秒针的节奏念一下。 实际教学时，还可以进行这样的活动:同学们闭上眼睛，老师说开始，你觉得1分钟到了就举手示意，看看谁对1分钟的估计比较准。 (二)简单的时间计算 1(例1(时间单位间的换算) 计算2时等于多少分时，由于还没学习这样的乘法，所以，学生用加法计算即可。但时间单位间的进率是60这一点一定要让学生牢记。 2(例2(一般的计算) (1)教材提供了学生从家出发去上学的情景图，利用钟面给出时间的起点和终点，让学生计算这两个时刻之间的时间段。计算时，体现算法多样化思想，可以用数格子的方法，看分针走过了多少格，也可以用算式计算的方法来计算，并鼓励学生想出更多的方法。比如，可以直接数分针走过了多少小格，也可以用3×5计算。 (2)在这儿还只是简单的时间计算，教师在补充练习时也不要出跨“时”的题目，如6时40分至7时20分是多少分。 3(P62“做一做” 不要求学生用乘法来计算时、分、秒间的换算。 4(练习十四 第1题，联系生活实际，选择合适的时间单位，重点是培养学生正确的时间观念。 第2题，判断大小，判断的方法可以多样化，有的只需要进行简单的估算即可。如第1小题，只要知道90秒比1分多，不到2分，就可以了。 第3题，实践调查的题目，可以帮助学生了解许多常识，如光1秒钟能传播多少路程，声音1秒钟能传播多远，飞机1秒能飞多远，1分钟一般正常呼吸多少下等。 第4题，把认识时间和时间的计算结合起来，既要写出时刻，又要计算一段时间，算法多样，既可数格，也可计算。 第5题，联系生活实际让学生解决现实问题。 第6题，估计时间，培养正确的时间观念。 第7题，实际调查的题目，培养学生在日常生活中发现和应用数学的能力，可以结合电视预告的方式进行调查。而且体现了很大的开放性，喜欢什么节目就选取什么节目进行调查，教材中要求调查起始时刻，还可以让学生计算一下时间段。 第8题，利用学生的作息表进行时间的综合应用。 第9题，联系自己的作息时间填一下，使自己更合理地安排生活。 undertaking, strengthen the construction of party and Government personnel.
