一元一次方程与实际问题是七年级上学期的教学重点,也是难点.在教学的过程中,学生最为棘手的是如何从实际问题中建立方程模型.不少同学虽然掌握了常用的基本数量关系,但是具体到每一个实际问题中,往往不能确定每个数字的意义,即便有公式也不知道该怎么运用.
One dollar equation and the actual problem is the seventh grade last semester teaching focus, but also difficult.In the teaching process, the students the most intractable is how to establish the equation model from the actual problem.Many students although the master of the common basic quantitative relationship, However, to each practical problem, it is often not possible to determine the meaning of each figure. Even if there is a formula, it does not know how to use it.
