简便计算是学生在具备普通四则运算技能的基础上,灵活运用运算定律和数学基本性质,使计算简便。而当下简便计算的教学现状是学生学得苦,教师教得累,课堂效率低。小学三年级刚刚接触运用简单的数学基本性质进行简便计算,四年级开始学习运算律。高年级段则是在中年级的基础上引入小数、分数的简便计算。怎样让我们的简便计算变得真正简便而有实效呢?笔者以为,融 Simple calculation is that students have common four arithmetic skills, based on the use of mathematical laws and mathematical flexibility to make the calculation easy. The current simple calculation of the status quo of teaching students learn hard, tired of teaching teachers, classroom efficiency is low. The third grade of primary school has just come into contact with the basic nature of simple mathematics for easy calculation, the fourth grade began to learn arithmetic law. Senior grades is the introduction of the middle and lower grades based on the simple calculation of scores. How to make our simple calculations become really simple and effective? I think, financial
