20以内加减法的技巧

20以内加减法的技巧 一、手指辅助延伸法。 例1:计算6+8= 我至今记得有这样一位小朋友,5以内的加减法很勉强能通过,10以内的就得靠他那10个手指头了.当我们教到20以内的加减法时他就束手无策了,无奈只好脱掉鞋子把自己的10个脚趾头也搬了上来.对于这样的学生,我起初真的也束手无策了,这样下去该如何是好,总得想出点办法来。看着自己的双手我也动了一番脑筋,于是我就把一只手看成是9,大拇指代表5,其他各指都代表1,另外一只手也是如此。 以例1计算6+8= 为例,计算像这样20以内的进位加法时,我就告诉他:左手拿出6(大拇指加食指),右手拿出8(大拇指加另3个手指),然后把两个大拇指合起来就是10(5+5=10),再数数还有几个手指(4个),那合起来就是十几了(14)。就这么反复的教了几遍后,这位小朋友就明白了我的意思,以后做20以内的进位加法速度也快多了,比以往手指、脚趾并用得心应手多了。计算20以内的进位加法都可以用这种方法来解决。 低年级学生尤其是一年级学生以具体形象思维为主要形式,对“一只手是5个手指头,两只手合起来是10个手指头.”这一概念在幼儿时期就已经形成在小朋友的大脑中了。我只是让他们把这一概念继续延续下去,两个大拇指一并就是10,然后数数还有几个手指就是十几.因

为我把20以内的进位加法转化成为10以内的加法和整十数加几的加法了,这对小朋友来说要比进位计算简便的多,所以学生计算速度大大 提高了。 后来,我也把这种方法教给了计算速度很一般的小朋友,他们的速度也有了大大提高。 在教学活动中,我们不光要注重交给学生理论知识,面对学困生不要一味地用同一种方法去教学,要尽可能想出一些巧妙既便于记忆的方法来,只要结果相同,教无定法. 二、将错就错倒减法。 例2:计算 15-8= 这是20以内的退位减法,在教学生的过程中,我们老师一般教学程序如下:让学生把被减数15分成10和5,然后用10去减8还多出2,再与5相加等于7,所以15-8=7,而且在练习的过程中教师都非常注重过程,还要让学生说说是怎样做的.这对一些成绩优秀的学生来说 是小菜一碟,有的甚至已经能熟练地口算了.中等生一般都会一步一个脚印地跟着老师走,可想而知,速度会较优生慢许多。而对那些刚对20以内加法有那么“一点点熟练”的小朋友来说无疑碰到了难题,他们往往是这样做的:个位上5减8不够减,他就倒过来8-5=3,所以把15-8的答案做成13.面对这样的后进生,教师更应设计好攻难坡度,多花时间耐心指导.以例2为例,我尝试使用了“倒减法”:就是在学生

20以内加减法巧算与速算方法

20以内加减法巧算与速算方法 例1. 6+5 7+9 思路导航: 计算6+5时,可以这样想:6比5多1,把6换成5+1,用5+5+1=11,所以6+5=5+5+1;或者把5换页6-1,用6+6-1=11,所以6+5=6+6-1=11。 计算7+9时,可以这样想:9+()=10,9+1=10,从7里拿出1给9,把9凑成10,7剩下6,6+10=16,所以7+9=16。练习题:比一比,看谁算得又对又快。 3+8 6+9 5+6 8+7 9+8 4+5 例2. 15-8 14-9 思路导航: 计算15-8可以这样想:8+()=15,因为8+7=15,所以15-8=7.也可以这样想:15可以分成10和5,10-8=2,2+5=7,所以15-8=7。 计算14-9,减数是9,个位不够减,用10-9=1,1与被凑数个位上的4想加得5,因此,可以直接用4+1=5来计算。练习题: 16-8= 12-3= 11-4= 18-9= 10-4= 15-7= 12-8= 15-9 例3.2+7+8 思路导航:

计算2+7+8时,我们发现如果把先加的7与后加的8交换加的顺序,先加8,再加7,就变成2+8+7,2+8=10,10+7=17,这样片区起来比较简便。 2+7+8=2+8+7=10+7=17 练习题: 1+8+9= 3+7+2= 4+2+8= 6+5+4= 6+5+5= 9+7+1= 例4.1+3+5+7+9 思路导航: 如果按从左往右的顺序进行计算,不但麻烦,而且很容易算错。通过仔细观察算式中的各个加数,可以发现1+9=10,3+7=10,这样可以把能凑成10的数先加起来。因此1+3+5+7+9=(1+9)+(3+7)+5=25 练习题: 2+4+6+8+10= 2+7+3+4+8= 5+4+9+5+6+1= 1+3+5+7+9+10= 例5.15-7-3 思路导航: 计算连减的算式时,如果按从左往右的顺序进行计算,第一步就是退位减法,容易算错。如果认真分析算式就会发现,两次要减去的数合起来正好是整十数,这样我们可以把要减去的两个数先合起来,然后一次减,这样做起来,又对
