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”。

·Grow with me 100以内的加减法(巧算基础)
一、两位数加一位数(进位)
44+8=
(1)凑整十: 1、第一个加数凑整十
44差6变50 此时将第二个加数8变成6+2
44+6=50 此时还有2没有加
50+2=52
2、第二个加数凑整十
8差2变10 此时将第一个加数44变成42+2
8+2=10 此时还有42没有加
42+10=52
(2)先加个位:4+8=12
40+12=52
二、两位数加二位数(进位)
44+28=
(1)凑整十: 1、第一个加数凑整十
44差6变50 此时将第二个加数28变成6+22
44+6=50 此时还有2没有加
50+22=72
2、第二个加数凑整十
28差2变30 此时将第一个加数44变成42+2
28+2=30 此时还有42没有加
42+30=72
(2)十位、个位分开加
40+20=60
4+8=12
60+12=72
三、两位数减一位数(退位)
44-9=
(1)先减到剩整十: 44先减4 44-4=40
再减剩下的5 40-5=35
(2)先由被减数个位向十位借位再减: 14-9=5
再加上剩下的被减数 30+5=35
四、两位数减二位数(退位)
44-19=
(1)先减到剩整十: 44先减4 44-4=40 44先减14 44-14=30
再减剩下的15 40-15=25 再减剩下的5 30-5=25 (2)先由被减数个位向十位借位再减个位: 14-9=5
再减剩下的十位数 30-10=20
加上上面两个数 20+5=25
** 加减时如果没有进位及退位的问题时就用正常的运算
五、练习
53+8 29+5 17+45 46+18 54+29 74+19 35-8 42-7 73-37 46-28 66-17 93-48。
