理解与表征数量关系是解决问题的前提,也是解决问题的根本。如果呈现的信息和问题比较复杂、抽象,学生的思考有障碍,往往会陷入解决问题的困境。教师应引导学生寻找数量关系,合理选择不同的数学方式加以表征,学会利用多种方式表达自己的思考过程,发展学生的思考力,提高解决问题的水平和类化的能力,才能在面对全新的问题时,找到切入点,一步一步加以解决。人教版《义务教育教科书·数学》六年
Understanding and characterizing the quantitative relationship is the prerequisite for solving the problem and also the fundamental solution to the problem. If the presented information and questions are more complex and abstract, students’ thinking has obstacles and often falls into the dilemma of solving the problems. Teachers should guide students to find the number of relationships, reasonable choice of different mathematical ways to characterize, learn to use multiple ways to express their thinking process, develop students’ thinking skills, improve the level of problem-solving and the ability to classify in order to face the new When finding the starting point, solve it step by step.
