数学解题是数学学习的重要活动之一,更是检验学生学习效果的主要方式.而数学解题的第一步便是读题,就是对问题材料进行观察、审视,从而引发一系列的思维活动,进而形成相应的解题方案,然后再用数学语言进行陈述,即通过严密的推理、准确的计算来解决问题.然而经常有同学因对题情观察不仔细,导致解题犯低级错误(特别是数学填空题).有时因观察不到位,对关键处(即所谓题眼)缺乏观察而不能突破;有时因对题目隐 Mathematical problem solving is one of the important activities of mathematics learning, but also the main way to test the effect of learning.And the first step in solving mathematical problems is to read the questions, which is to observe and examine the material of the problems and trigger a series of thinking Activities, and then form the appropriate solution to the problem, and then use mathematical language statements, that is, through rigorous reasoning, accurate calculation to solve the problem.However, often students do not carefully observe the problem, leading to mistakes mistakes ( Especially mathematics fill in the blank question.) Sometimes because of observation is not in place, the lack of observation of the key office (the so-called problem of eye) can not be broken; sometimes because of the problem of hidden
