“数的运算”是小学数学教学的重要内容之一,也是小学生必须掌握的一个重要数学技能。它是学生从事其他数学学习活动的基础,如果学生的计算能力得不到发展,那么就谈不上其他数学技能的培养。计算教学不像解决其他数学问题那样思路复杂,需要学生具有一定的思维空间,所以一直被许多数学教师所忽略,在教学计算内容时,总认为没有什么算理可讲,只是机械重复地让学生做大量的计算题。
“Number of operations ” is an important part of primary school mathematics teaching, but also an important mathematical skills that pupils must master. It is the foundation for students to engage in other math learning activities and can not speak of the development of other math skills if their computational skills are not developed. Computational teaching is not as complicated as solving other mathematical problems, and requires students to have a certain space of thinking. Therefore, it has been neglected by many math teachers. When teaching computing contents, it is always considered that there is no reason to say that the teaching is repeated mechanically Do a lot of calculation problems.
