逆向思维是数学思维重要的表现形式之一,在解应用题中发挥着重要的作用。因此,在小学数学教学中要对学生进行逆向思维的训练。在解题过程中通过逆向思维可以解决常规办法无法解决的问题,这样,学生在解题过程中就会思维敏捷、思路开阔。一、对于思路繁琐的应用题,引导学生逆向思考解决应用题是小学数学教学的重要内容,但是有些应用题条件复杂,要解决的问题让人一时难以找到解决的思路。遇到这种情况,教师不妨引导学生能由眼前的已知条件,解决问题的 Reverse thinking is one of the important manifestations of mathematical thinking, and plays an important role in solving applied problems. Therefore, in primary school mathematics teaching students to reverse thinking training. In the process of solving problems through reverse thinking can solve the problems can not be solved by conventional methods, so that students in the problem-solving process will be quick thinking, open-minded. First, the tedious questions on the application of ideas to guide students to reverse thinking to solve the problem is an important part of primary school mathematics teaching, but some of the problems are complex, the problem to be solved for a while difficult to find a solution. In this case, teachers may wish to guide students from the immediate known conditions to solve the problem
