一年级心算速算技巧?

心算速算——简称快心算,也叫“口算”,数学教学方法之一。一种只凭思维及语言活动不借任何工具的计算方法。它能培养学生迅速的计算技巧,提高学生的注意、记忆和思维能力。

心算速算技巧

凑十法

凑十法”是进位加法的基本思路。运用“凑十法”能够把进位加法转化成整10加几的问题,从而达到化难为简的目的。

口诀

一九一九好朋友,二八二八手拉手,三七三七真亲密,四六四六一起走。五五凑成一双手。看大数,分小数,凑成十,加剩数。大数记心里,小数记手里。

一加九,十只小蝌蚪,二加八,十只花老鸭,三加七,十只老母鸡,四加六,十只金丝猴,五加五,十只大老虎。看到9想到1,看到8想到2,看到7想到3,看到6想到4。看到大数加小数,先把两数换位置。

含义

把一个加数分解成两个数,使得其中分解的一部分和另一个加数相加得到10,再用10加另外一部分数的方法,这就是凑十法。其基本原理是先使两个数的和凑成10,再化成10加几的计算方法。

技巧

比如:9+2=( ),根据“凑十法”:“9”和“1”是凑成“10”的,即9+1=10,后面的“2”分出“1”后就只剩下“1”了,所以:10+1=11。其他以此类推,如:

破十法

破十法要指当个位不够减时,就用10减去减数,剩下的数和个位上的数相加。

口诀

减九加一,减八加二,减七加三,减六加四,减五加五,减四加六,减三加七,减二加八,破大数,加小数。

技巧

比如:11-4,1-4个位数不够减,所以就从11(10+1)里,用10减去4,就等于6了,再用剩下的数字6和十位数上的1相加,等于7。

其他例子计算过程如下图所示:

进位加法

方法一:“凑十法”(强调:看大数,分小数,凑成十,加剩数)。比如:8+5=8+2+3=13

方法二:“五五凑十”(当两个加数都大于且接近5时适用)。比如:6+7=5+5+1+2=13

方法三:“多加减补”,比如:8+5=10+5-2=13。

退位减法

就是当两个数相减,被减数的个位不够减时,往前一位借位,相当于给这位数加上10,再进行计算。

口诀

几减九退十加一、几减八退十加二、几减七退十加三、几减六退十加四、几减五退十加五、几减四退十加六、几减三退十加七、几减二退十加八、几减一退十加九。

做减法想加法

利用减法是加法的逆运算关系,用加法来思考。这个方法是在之前学习的进位加法基础上进行的。例如,想()+9=27?(18)+9=27,所以27-9=18。这个方法运用好的前提就是进位加法必须得掌握好。

例如:11-9=(?),要想9+(?)=11,这样就知道得多少了。

连减法

连减法是一个数连续减两个数,可以等于这个数减两个数的和,得数不变。

口算方法比较多,如何找出适合自己的最佳方法是提高口算速度及正确率的关键。练习时可以和学生一起复习多种口算方法,让学生通过比较,得出最佳的方法。提高计算能力,光掌握技巧是不够的,还需要通过不断做题练习巩固,正所谓“熟能生巧”,这就需要老师或家长每日为宝贝出练习题来巩固技能,特别注意的是:不要让孩子数指头,改掉不良习惯,逐步培养心算能力。

心算的训练

第一步:会动作上简单的计算从加减一开始用动作计算。

拿一个,家长说1加1,孩子由一个再加上一个,孩子快速报2,然后计算2+1=3,一直算到二十。算到二十再一个一个的减回来。注意,一定要算式和动作动应。

分析:从动作到物品到数概念的理解,是一个量变到质变的过程,家长一定要细心!

第二步:用简单的计算题练习速度从纸上随意位置从一写到十,让孩子看数后快速加上一或减去一。

这样把十或二十以内的加减一练习相当熟练了(一秒一题),孩子就养成了一个快速计算的习惯。以后再学习其它计算,孩子也想尽快答出来。起初,孩子计算会常常算错,但孩子在一秒钟以内就能感觉算错了。

分析:计算其实就是1+1,这个搞懂了,其他就不用怕了。

第三步:循续渐进的练习其它计算

这里重要提示:计算题就只写一张纸二十题就行,单页训练,不要怕重复。

工具书推荐

《神奇的逻辑思维游戏书》

这本书以彩色图片的形式展示,更直观,解析同样是图解,尤其是排列顺序的问题。这本书所选的题目来自“世界趣味数学”,旨在培养孩子从多角度看问题的能力,对孩子的吸引力更大些。

《10倍速心算》

这本书很适合家长引导孩子学习心算方法,例题和各种解法,无论是通过文字讲解或是习题慢动作回放,都是思路展示,家长都可以引导拓展孩子的解题思维,这样也能帮助孩子逐步摆脱老师是否说过或教过,才可以接受新方法,这才能进入主动学习的状态。

心算的好处

(1)心算速算可以有效的开发大脑的潜能。

教学法通过手的灵活性和大脑对手控制精度的训练,模拟电脑运算原理从而形成最简捷的计算方式。

(2)心算速算一旦掌握终生受益。

脑算是最实用的技术。全脑速算的教学过程不需要任何教具就能进行。不受空间地点的限制。

(3)心算速算教学效果奇特。

4-12岁的孩子通过45次课的系统学习就能快速脑算任意数加、减、乘、除、乘方及验算。其速度可超过计算器。

(4)心算速算通过手的活动刺激大脑,最终让孩子用脑算代替手算。

遵循全脑开发循序渐进的原理。

(5)数学是所有科学的工具和基础。

心算速算的运算原理以有韵律的文字口诀表现出来,促进学科间的相互渗透,全面提高孩子的综合能力。

(6)心算速算的训练过程就是大脑记忆能力和快速反应能力的开发。

脑算能力好的人自然是大脑的记忆容量大和反应速度快。

(7)心算速算使左右手的快速伸屈刺激了左右脑细胞的兴奋。

使左右脑平衡发展,同时活跃起来参与记忆和思维。促进智能开发。

(8)心算速算提高孩子的操作技能。

技能的训练,都是手脑协调的训练,即大脑对手的控制指挥能力的训练,训练手脑配合的协调,使手变的灵巧自如,从而促进孩子的潜能开发。
