小学数学《100以内加减法练习课》听评课

100以内加减法练习课 听评课 一、巧妙利用学生错例 选用来自于学生中的典型错例,让学生感到这些错误的真实存在,更加能引起学生的重视。 教师深入了解学生学情,对学生错题原因进行了细致分析,梳理总结,选用了学生错题中的典型,很具有针对性,本节课共设计了三组错例展示: 第一组即微视频中这一组突出的是相同计数单位相加减的算理,是加减法计算之根本。在两个加数(被减数和减数)数位不同的时候,如两位数加减一位数,就特别容易加(减)错数位。本节课老师选取的这组错例很有代表性。 第二组是关于进位、退位的错例。这是一组对学生来说“知易行难”的问题,学生知道进位甚至写着进位“1”,就是忘记加上“进位1”。老师在课上展示了这种类型的错例,再次引起学生的注意,并且让学生想出小妙招怎样做可以减少这类错误的发生。 第三组是由于基础加减法不扎实导致的错误,如错例45-8=36。是由于15-8计算错误导致了最终结果的错误。老师引导学生要注重20以内基础口算的计算,强调了知识之间的密切联系。 以上三组错例几乎包括了计算加减法中的全部错误,老师准确的进行了总结、分析,对学生今后的计算起到了引领、指导、强调的作用。

二、直观演示进一步理解算理 作为老师不能单纯把学生的出错看作是粗心造成的,我们应该在算理和算法的理解方面多下功夫,借助有重点的讲解、直观的演示和有针对性的练习,帮助学生理解和掌握这一计算的重点。不要让学生孤立的计算,而是提供加减法计算的本质,有利于学生的转化思维培养。 在本节微视频中,老师适时利用小棒、计数器等直观教具展示算理,再次让学生理解相同计数单位相加减的算理。 三、改进建议 增加圈、箭头之类的指示标志,让学生更清晰理解计数单位的意义。 适当增肌拓展练习,将相同计数单位相加减的算理拓展延伸到学生还没有学习过的领域,体会这一算理的重要性。

100以内的加减法计算练习课 教案

《100以内的加减法》计算练习课教学设计 骏威小学郑景玲 教学内容:人教版12——22页的内容。对100以内数的加减法计算方法、重点以及易错点进行针对性的练习。 教材分析:100以内加减法,即是对已经学过的20以内加减法计算的巩固和应用,又是学习多位数加、减法以及乘、除法的基础,具有承上启下的作用,因此,这部分内容学习的好坏将对以后计算的正确性和速度产生直接的影响。基本内容如下: 整十数加、减整十数 100以内数的加减法:两位数加一位数、整十数(不进位) 两位数加一位数(进位) 两位数减一位数、整十数(不退位) 两位数加一位数(退位) 这部分内容是本单元的重点,其中两位数加一位数、两位数(进位),两位数加一位数、两位数(退位)是教学的难点。所以在学习完以上部分以后,很有必要进行一次对比较难,比较容易出错的计算题进行一次有针对性的练习课,以进一步巩固100以内数的加减法让学生进一步内化算理和算法,为今后的学习打下坚实的基础。 学生情况分析:在学习这部分内容以后,大部分的学生已经掌握了正确的计算方法,尤其是不进位加法和不退位减法这两种类型的题目掌握较好,基本明白了相同数位的数才能直接相加减。但部分学习有困难的学生,对于进位加法以及退位减法的计算方法存在有一定的问题,还会因为20以内数的加减法掌握不牢固,或做题时没有认真的审题,还

会出现对错数位、看错符号等现象,具体问题如下: 1、20以内的加减法不过关。如:6+7 7+8 13-5 12-4等 2、进位加法不进位,退位减法忘记退位。如:34+7=31 52-29 =23 3、不同数位相加的。如:38+5=88 74-6=14 4、看错符号的:把加号看成减号,把减号看成加号。 除了出错之外,部分孩子的计算的速度比较慢。为此,本节课将通过有针对性的有趣的题组练习,帮助学生扫除计算上的障碍,并提高学生计算的兴趣。 教学目标: 1、进一步理解、巩固本单元所学的100以内数的认识、加减法知识。 2.经历整理与复习的全过程,初步形成归纳、整理知识的能力。加深理 解知识间的内在联系,能综合运用所学知识解决简单的实际问题。 3.通过对知识的整理与复习,逐步养成回顾和反思的习惯,感受学习数 学的快乐,增强学习数学的自信心和成功感。 教学重点:对“进位加法不进位,退位减法忘记退位,数位没对齐等” 情况进行纠正。 教学难点:提高计算的准确率和速度。 一、课前三分钟(欣赏思维导图) 今天的课前三分钟是我们一起来欣赏小朋友们做的思维导图。请欣赏(PPT展示并配乐)这孩子它是以一座碉楼的形式展示了100以内加减法的知识,计算中有口算、笔算,而在这些计算中有加法和减法,加法中又有进位加和不进位加,减法中有退位减和不退位减。这些都是我们
