在以往的教材中,解方程的依据是四则运算之间的关系。虽然现行的教材不再系统呈现这一方法,但学生在学习加、减、乘、除四则运算的过程中已经反复感知这些关系,积累了丰富的感性经验,所以若能运用这些关系解方程,正确率会大大提高,不管是教师教还是学生学都会感到轻松。但是,依据四则运算之间的关系解方程,只能暂时让学生在小学走得快一些,到了初中很快就会碰
In the past textbooks, the basis for solving equations is the relationship between the four operations. Although the current teaching material no longer presents this method systematically, the students have repeatedly perceived these relations during the process of learning addition, subtraction, multiplication and division and have accumulated rich and sentimental experience. Therefore, if these relations can be used to solve equations, The correct rate will be greatly improved, both teachers and students will feel relaxed. However, according to the relationship between the four arithmetic solution equation, only temporarily allow students to go faster in primary school, junior high school will soon touch
