乘法口诀表背法参考:
1、竖向背诵:这种方法有个规律,几的竖列,就逐渐增加几,可以按此规律帮助记忆。
2、横向背诵:这种方法也有个规律,第几行,后一句就比前一句增加几。
3、要形成长久的记忆,可以每天背诵两个十分钟(将一天白天时间分成两个时段,每个时段背诵十分钟),并且随机抽取一个背诵时间段,边背诵一边在纸上默写,这样更能加深长久的记忆。
乘法口诀表是从“一一得一”开始,到“九九八十一”为止,源于乘法口诀,方便乘法计算的简单乘法表。这是我们每个人应该掌握的快速计算个位数乘法的方式。而背诵乘法口诀表可以快速的记住个位数乘法结果,方便日后使用。

如何快速背乘法口诀

其实乘法口诀就那么一点,只要天天读,天天写,一行一行背,第一行背好,再背下一行,下一行背好两行连在一起再背,然后再背第三行,第三行背完,再三行一起背......一直这样反复背下去,再加上家长提醒、提问(打乱顺序),孩子很快就会掌握。若一定要问有什么技巧,那我就谈一下一点小窍门:
从1到5,你可以让他自己想:二二就是两个二相加,三三就是三个三相加,四就四个四个加,五就是五个五个加,孩子如果了解了乘法的意义,就可以很快找到得数怎样来的,然后帮助孩子寻找积的规律让孩子巧记。这样他们会很快掌握。
有的特殊的挑出来:如
三八二十四与四六二十四对六七四十二
二七十四对五八四十
四九三十六与六六三十六对七九六十三
二九十八与三六十八对九九八十一
三四十二与二六十二对四五二十
六九五十四对五九四十五
八九七十二对三九二十七
后面的得数都是反过来的。二八十六与四四十六得数一样(上面的几个“与”得数一样的挑出来,以后的数学题上会出现这样的题目——写几个不同的算式使得积是一样的)
九较特殊,也好记:你可以让孩子伸开双手,一九让他弯下左手拇指,看两只手剩下九就得九,二九你让他弯下左手第二个手指,弯下的手指左边剩下1个作为十位数,右边剩下8个作个位数就得十八,三九你让他弯下左手第三个手指,弯下的左边有2个右边有7个,所以是二十七......以此类推,很快掌握。
几个特殊的也要记住:
5×3=15 6×6=36 8×6=48 2×6=12 4×6=24
5×5=25 5×7=35 5×9=45 这些算式的第一个乘数与积的个位数相同,以后会做到类似的题目:把以下的方框填上相同的数(或整十数)使等式成立:□×3=1□ □×6=4□...
希望能帮到你,愿你的孩子早日背熟乘法口诀,为将来的学习打下良好基础!

横着背

比如第一横行,就一句一一得一;第二横行两句,一二得二,二二得四;往下类推,第几行就几句,最后九句,从一九得九到九九八十一。这种方法也有个规律,第几行,后一句就比前一句增加几。

理解族的精灵擅长逻辑推理。当他们能按顺序熟读口诀后,必然会有若干自己比较熟悉的口诀,例如: 二五一十、九九八十一等,将这些口诀作为参照物,可运用推算的方法很快找到与之相邻的乘法口诀,比如:8×9的结果想不出,则可思考“9个9减去一个9”,也就是“81-9=72”,当然得出结论后不能写上72就算了,还应把“8×9”的口诀在心里默念一遍,那么多经历几次这样的思考后,“八九七十二”这句也将成为铭记于心的口诀了。这样以点带面,从若干口诀辐射到所以口诀,效果应该会比较明显。还有图式记忆法,列表记忆法,顺口溜记忆法。
