五年级本月学习内容主要有《小数乘法》与《小数除法》。小数乘法的主要学习内容是:1.帮助孩子们理解和掌握小数乘法的意义及计算方法。它的意义与整数乘法的意义相同,也是求几个相同加数和的简便运算。计算时先按照整数乘法的方法计算,再看因数中一共有几位小数,就从积的右边起数出几位,点上小数点。如果积的小数位数不够,用0补足,再点上小数点。2.会用四舍五入法求积的近似值;3.能合理、灵活地运用整数乘法的有关定律进行小数乘法的简便计算。简便计算看(?)家长要耐心帮助孩子理解意义。
Fifth grade this month’s main learning content “decimal multiplication” and “decimal division.” The main contents of fractional multiplication are: 1. Help children to understand and master the meaning and calculation method of fractional multiplication. Its meaning and the meaning of integer multiplication is the same, but also seek a few simple sum of the same sum. Calculate the first integer multiplication method to calculate, look at a total factor of a few decimal places, from the plot on the right out of a few, the point on the decimal point. If the product of the decimal places is not enough, with 0 make up, and then click on the decimal point. 2 will be rounded to the approximation of the product; 3 can reasonably and flexibly use the law of integer multiplication of the simple calculation of fractional multiplication. Easy calculation to see (?) Parents should be patient to help children understand the meaning.
