生:我想把个位上的数相加,再加整十数。 学生说教师板演。 64+5二69 60 4 9 二、新知讲授。 课件出示“海宝”介绍上海世博会的资料。 1、创设情境,提出问题。 (1)观察主题图,找到数学信息。 课件出示,师:观察这幅图,你知道了哪些数学信息? 指名回答 (2)发现问题,提出问题。 师:如果你是每个年级的领队老师,首先要考虑什么?预设:应该考虑要买多少张车票? 师:你能提出什么数学问题?指名提问题。

2、自主探究,掌握算法。 (1)教学例1 教师选择性地板书问题:“一年级一共要买多少张车票?” 师:你会解决这个问题吗?请你写在练习本上。 学生独立列式计算。 汇报交流。 35 + 34 = 6935 + 34 二69 5 3030 4 6465 30+30=60 5+4=9 60+9=69 (2)教学例2 选择学生提出的“二年级一共要买多少张车票?”的问题,针对学生列出的算式39+44二?让学生独立思考,用自己的方法进行口算。 汇报交流。

口算两位数减一位数

口算两位数减一位数(退位减法) 教学内容:79~80例二,想想做做1~4 教学目标: 1、使学生经历探索两位数减一位数退位减口算方法的过程,理解退位减的算理,掌握两位 数减一位数退位减的口算方法,能正确口算两位数减一位数的得数。 2、使学生在提出问题和探索口算方法的过程中,发展提出问题、解决问题的初步能力;在 合理探寻新知的策略和有条理表述口算过程中,发展形象思维和抽象、概括等初步的思 维能力,以及口算能力,进一步积累运用已有知识、经验学习新内容的经验。 3、使学生在动手操作与合作交流中,产生对数学活动的兴趣,初步培养合作交流的意识, 体会学习成功,提升学习数学的自信心。 教学重点:两位数减一位数退位减的口算的方法 教学难点:理解两位数加一位数退位减的算理 教学准备:多媒体光盘、小棒、口算卡片 教学内容: 一、复习旧知,铺垫引入 1、口算: 14—6 = 10一8= 13一5= 15—7= 12— 7= 14—5= 47-4= 23-2= 35-2= 20-10= 28-8= 46-3= 谁来说说47-4是怎样算的?35-2呢?(板书口算过程) 指出:这里的两位数减一位数,先算个位减个位,再把几十和减的数合起来。 1、说明课题,激发动机 说明:刚才的两位数减一位数,小朋友都能计算,今天我们仍然要学习两位数减一位数(板 书课题)今天我们学习两位数减一位数会和之前学的有什么不同?要怎样算?学好之后请小 朋友来说说,有信心学好今天的知识吗? 二、探究新知。 1、出图仔细观察提问:三个小朋友各有多少张画片?(30张、34张、8张) 你能提出用减法解决的数学问题吗? 提出问题,列出算式,板书: 小华比小丽多多少张? 30-8 小军比小丽多多少张? 34-8 小军比小华多多少张? 34-30 提问:哪道算式是我么学过的?你直接口算? 1、探究算法 (1)30-8 提问:这是两位数减一位数,按照以前的算法,先用哪一位上去减?你发现什么问题/ 引导:奥,这里个位上的0不够减。怎么算?想想能用什么办法来解决? 小朋友真不错,想到可以用小棒来解决。同桌两人合作,用小棒摆一摆,算一算,说一说。 交流:你是怎样摆的怎样算的? 交流演示小棒、启迪算法:先摆出3个十是30,没有单根可以减,就从1里减。把这一捆拆开来(拆成10根),可以减8了吗?从拆的10根里拿走8根,还剩2根,再把20和剩

《两位数减一位数退位减法》教学设计 教学内容: 人教版《义务教育课程标准实验教科书数学》一年级下册第68页例2:两位数减一位数的退位减法口算 教学简析: 《两位数减一位数的退位减法》是义务教育课程标准实验教科书人教版数学第二册P68的教学内容。两位数减一位数退位减法口算这一知识点,是数学第二册第二单元中的一个难点,怎样突破这个难点,我想还是应该充分发挥多媒体的优势,创设情境,由情境引入,充分利用“6减8不够减怎么办”的矛盾引起学生的认知冲突,以此激发学生主动探索退位减法计算方法的心理需要。 教学设想: 本节内容是在学生已经掌握整十数加减整十数、两位数加、减一位数和整十数的基础上教学的,关键让学生通过动手操作,理解和掌握两位数减一位数退位减法的计算方法,并能用自己喜欢的方法进行正确计算,感受退位减法与实际生活的紧密联系,体会退位减法在生活中的作用。 教学中借助多媒体课件,从学生喜欢的玩具开始,激趣引入,为学生提供富有情趣的具体情境。在具体情境中激发学生的学习兴趣和主体性。使学生以最佳的思维状态投入学习,为学生发展提供了更广阔的空间。通过这节课教学,旨在让学生体会生活中处处有数学,学习数学是生活的需要,学好数学从点滴开始;同时让学生认识到数学有趣、好玩,进而学好数学、好学数学。 教学目标:

知识目标: 1、掌握两位数减一位数退位的计算方法,并能用自己喜欢的方法计算。 2、经历两位数减一位数退位减计算方法的探索过程。 3、培养学生计算能力和动手操作的能力。 德育渗透: 感受退位减与实际生活的密切联系,体会退位在实际生活中的作用。 教学重、难点: 两位数减一位数的退位减的计算方法。 教学准备: 课件、小棒、卡片。 教学过程: 一、课前铺垫 (教师为同学们准备好100根小棒,装成一袋) 1、捆小棒 师:老师为大家准备了一些小棒,请同桌配合,把这些小棒捆成10根一捆10根一捆的。 学生动手操作,师巡视指导 2、拿小棒 老师说出一个数,让学生拿出对应的小棒。 (1)整十数如20、80(让学生进一步认识100以内的整十数) (2) 几十几如35、48等。(让生初步感知“破十”) 【设计意图:复习铺垫,其次增强学生之间的相互协作,培养学
