小学一年级数学《手指速算100以内加减》帮助孩子学习

小学一年级数学《手指速算100以内加减》,帮助孩子学习!手指速算100以内加减一、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“l”,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”。
(1)个位数加法练习(10以内加法练习)1+12+l、2+23+l、3+2、3+34+l、4+2、4+3、4+45+1、5+2、5+3、5+4、5+51+1、1+2、1+3、1+4、1+5、1+6、1+7、1+8、1+92+l、2+2、2+3、2+4、2+5、2+6、2+7、2+83+l、3+2、3+3、3+4、3+5、3+6、3+74+l、4+2、4+3、4+4、4+5、4+65+1、5+2、5+3、5+4、5+5(2)十位数加法练习10+1020+l0、20+2030+l0、30+20、30+3040+l0、40+20、40+30、40+4050+10、50+20、50+30、50+40、50+5010+10、10+20、10+30、10+40、10+50、10+60、10+70、10+80、10+9020+l0、20+20、20+30、20+40、20+50、20+60、20+70、20+8030+l0、30+20、30+30、30+40、30+50、30+60、30+7040+l0、40+20、40+30、40+40、40+50、40+6050+10、50+20、50+30、50+40、50+50(3)一百以内加法混合练习3+5、4+5、l+5、6+5、8+7、9+l、9+3、7+1013+12、24+17、49+2、47+6、43+8、46+54,38+62……(4)一百以内连加混合练习23+18+19+24+16、18+6+49+27……七、双手减法练习减法很简单,小指开始减,退位要记住,指法要熟练。
