加减法速算法
![加减法速算法](https://img.taocdn.com/s3/m/07cefa7271fe910ef02df892.png)
加减法速算法练习先计算,再找规律。
例1:口算:56+99=〔〕简算:56+99 先把99看作整百数是〔〕=56+〔100〕-〔1 〕因为整百数比原数多加〔 1〕,所以要减〔 1〕。
试练:先口算,再简算。
67+197= 148+298= 783+999=67+197 =148+298=783+999=规律一:两数相加想一想,看哪个最近整百〔千〕数,多加几要减〔〕。
例2:口算:56+102=〔〕简算:56+102 先把102看作整百数是〔〕=56+〔〕○〔〕因为整百数比原数少加〔〕,所以再加〔〕。
试练:先口算,再简算。
67+107= 148+208= 783+1005=67+107 148+208 783+1005规律二:两数相加想一想,看哪个最近整百〔千〕数,少加几再〔〕。
例3:口算:256-199= 〔〕简算:256-199 先把199看作整百数是〔〕=256-〔〕○〔〕因为整百数比原数多减〔〕,所以要加〔〕。
试练:先口算,再简算。
267-199= 348-298= 2283-999=267-199 348-298 2283-999规律三:两数相减看减数,哪个最近整百〔千〕数,多减几要〔〕。
例4:口算:256-102=〔〕简算:256-102 先把102看作整百数是〔〕,=256-〔〕○〔〕因为整百数比原数少减了〔〕,所以再减〔〕。
试练:先口算,再简算。
267-107= 348-208= 1783-1005=267-107 348-208 1783-1005规律四:两数相减看减数,哪个最近整百〔千〕数,少减几〔〕。
改变运算顺序速算在只有加减运算的算式中,有时改变加、减的运算顺序可使计算显得十分巧妙!例计算10-9+8-7+6-5+4-3+2-1解:这题如果从左到右按顺序进行加减运算,是能够得出正确结果的。
但因为算式较长,多次加减又繁又慢且容易出错。
如果改变一下运算顺序,先减后加,就使运算显得非常“漂亮”。

100以内加减法手指速算技巧一、手指定位口诀我有一双手,代表九十九;左手定十位,九十我会数;右手定个位,从一数到九;加减很方便,计算不用愁。
二、手指定数口诀食指伸开“1”,中指伸开“2”;无名指为“3”,小指伸开“4”;四指一握伸拇指,拇指是“5”要记住;再伸食指到小指,“6”“7”“8”“9”排成数。
三、右手出指练习口诀一马当先,二虎相争,三言两语,四海为家,五谷丰登,六畜兴旺,七上八下,八仙过海,九牛一毛,十万火急。
一言九鼎,二龙戏珠,三足鼎立,四面楚歌,五谷丰登,六神无主,七上八下,八面玲珑,九牛一毛,十全十美。
(注:念到“十万火急”或“十全十美”时,右手握拳,左手出“1”,代表进位。
)四、左手出指练习口诀一十,二十,三十,四十;五十,六十,七十,八十,九十,一百。
(注:念到“一百”时,双手击掌,然后紧握双拳在胸前。
)五、双手出数练习15、23、46、99、58、73、61 ……(注:根据各年龄段幼儿认知水平,选择出数的大小。
)六、加法练习注意:在做加法练习时,比如“3+5”,右手先出“3”,“+5”的过程是:嘴里念“加1”,出小拇指;嘴里念“加2”,四指一提伸大拇指(注意在出指的过程中大拇指只代表“1”,只有在定数的时候,大拇指才当成“5”);嘴里念“加3”,出食指;嘴里念“加4”,出中指;嘴里念“加5”,出无名指。
此时开始定数,右手手指只有小拇指未打开,结果即为“8”。

小学数学加减法计算速算技巧
![小学数学加减法计算速算技巧](https://img.taocdn.com/s3/m/892952c0cc7931b764ce1524.png)
小学数学加减法计算速算技巧“凑整”先计算两个数相加,若能恰好凑成整十、整百、整千、整万…则先计算。
如:1+9=10,3+7=10,2+8=10,4+6=10,5+5=10。
又如:12+88=100,35+65=100,21+79=100,44+56=100,55+45=100。
在上面算式中,1叫9的“补数”;79叫21的“补数”,44也叫56的“补数”,也就是说两个数互为“补数”。
例题1.计算下列等式:53+55+47 23+39+61解:式=(53+47)+55=155式=23+(39+61)=23+100=123对于不能直接凑整的,可以把其中一个数进行拆分,再凑整。
例题2.计算下列等式:87+15 54+79 65+18+27解:式=87+13+2=(87+13)+2=100+2=102式=33+21+79=33+(21+79)=33+100=133式=60+2+3+18+27=60+(2+18)+(3+27)=60+20+30=110对于没有直接凑整的数的,可以先凑整,最后再减去凑整的数。
例题3.计算:38+29+19解:原式=(38+2)+(29+1)+(19+1)-4=40+30+20-4=90-4=86等差数列计算等差连续数(等差数列)的和相邻的两个数的差都相等的一串数就叫等差连续数,又叫等差数列,如:1,2,3,4,5,6,7,8,91,3,5,7,92,4,6,8,103,6,9,12,154,8,12,16,20等等都是等差连续数.1,等差连续数的个数是奇数时,它们的和等于中间数乘以个数。
例题4.计算1+2+3+4+5+6+7+8+9解:原式=5×9(中间数是5,共9个数)计算1+3+5+7+9+11+13解:原式=7×7(中间数是7,共7个数)=49计算2+4+6+8+10解:原式=6×5(中间数是6,共5个数)=302,等差连续数的个数是偶数时,它们的和等于首数与末数之和乘以个数的一半。
