很多学生平时看似学得不错,考试时却考不出来,关键一点就是“会而不对,对而不全”.本文结合平时的教学实践,对初中数学的易错题进行一些分类与解析,希望对同学们的学习有所帮助.在我们平时所犯的错误中,有的是不易察觉的,而有的本是可以避免的.例如所想与所写不一致,在填写计算结果时有单位没加单位,应用题解答过程不完整最后未答,分式方程不检验,解不等式组最后没有写成解集的形式等等.而就具体错误而言,现将同学们平时所犯错误分为以下
Many students usually seem to learn well, but when the test is not test out, the key point is that “will be wrong, not right.” In this paper combined with the usual teaching practice, junior high school math problems some of the wrong classification and analysis , Hoping to help the students’ learning.On the mistakes we usually make, some are not easy to detect, while others can be avoided.For example, you may want to write something inconsistent with the results when you fill out the unit Plus units, answer the problem is not complete application of the final answer, fractional equation does not test, the final solution of the inequality group did not write the form of solution set, etc. And for specific errors, now students usually make mistakes are divided into the following
