拓展知识:
根据算式的不同特点,利用数的组成和分解、各种运算定律、性质或它们之间的特殊关系,使计算过程简单化,或直接得出结果,这种简便、迅速的运算叫做简算。
这就需要在进行简便计算之前,要求学生对所学的性质、定律、规律等有透彻的理解和正确的使用。也就是说,这些知识能使计算过程简化,同时使用凑整、拆项、转化、拆数等技巧以达到速算的目的。根据我的归纳,常见以下几类题型:
(一)运用加法的交换律、结合律进行计算。要求学生善于观察题目,同时要有凑整意识。
如:5.7+3.1+0.9+1.3,等。
(二)运用乘法的交换律、结合律进行简算。
如:2.5×0.125×8×4等,如果遇到除法同样适用,或将除法变为乘法来计算。如:8.3×67÷8.3÷6.7等。
(三)运用乘法分配律进行简算,遇到除以一个数,先化为乘以一个数的倒数,再分配。
如:2.5×(100+0.4),还应注意,有些题目是运用分配律的逆运算来简算:即提取公因数。如:0.93×67+33×0.93。
(四)运用减法的性质进行简算。减法的性质用字母公式表示:A-B-C=A-(B+C),同时注意逆进行。
如:7691-(691+250)。
(五)运用除法的性质进行简算。除法的性质用字母公式表示如下:A÷B÷C=A÷(B×C),同时注意逆进行,
如:736÷25÷4。
(六)接近整百的数的运算。这种题型需要拆数、转化等技巧配合。
如;302+76=300+76+2,298-188=300-188-2,等。
(七)认真观察某项为0或1的运算。
如:7.93+2.07×(4.5-4.5)等。
总的说来,简便运算的思路是:
(1)运用运算的性质、定律等。
(2)可能打乱常规的计算顺序。
(3)拆数或转化时,数的大小不能改变。
(4)正确处理好每一步的衔接。
(5)速算也是计算,是将硬算化为巧算。
(6)能提高计算的速度及能力,并能培养严谨细致、灵活巧妙的工作习惯。
