在小学数学教学中,教给儿童系统的巩固的数学基础知识,使儿童能准确地掌握数的运算、一次函数的性质及其图象,并能进一步掌握整式的运算及一次方程的解法,为进一步学习数学打下基础,并能运用这些知识、技能、技巧解决日常生活和生产劳动中的实际问题,是主要的教学目的。为了达到这个目的,就必须重视基本概念的教学,使儿童建立基本数学概念。为什么这样说呢?举例来讲,譬如,要使儿童学会乘法,就必须使儿童明确乘法的意义,否则,就不能自觉地计算和运用。又如,儿童对“求一个数的几分之几”与“已
In primary school mathematics teaching, the consolidated mathematical basic knowledge taught to children's systems enables children to accurately grasp the operation of numbers, the nature of first-order functions and their images, and further grasp the integral operation and the solution of one-time equation It is the main teaching goal to learn more about mathematics and lay the groundwork and apply these knowledge, skills and techniques to solve practical problems in daily life and productive labor. In order to achieve this goal, we must attach importance to the teaching of basic concepts so that children can establish basic mathematical concepts. Why do you say this? For example, to make children learn to multiply, you must make children clear the meaning of multiplication, otherwise, you can not consciously calculate and use. In another example, the children of “a few minutes to find a few” and "already
