《数学课程标准》指出,在数学教学中要培养学生的应用意识,让学生认识到现实生活中蕴含着大量的数学信息,数学在现实世界中有着广泛的应用;面对实际问题时,能主动尝试着从数学的角度运用所学知识和方法寻求解决问题的策略;面对新的数学知识时,能主动地寻找其生活背景,并探索其应用价值。“解决问题”教学在整个小学阶段,尤其是高年级特别重要,既是重点又是难点。在“解决问题”教学中,要通过分析数量关系,引导学生掌握多种解题思路,同时教给 The standard of mathematics curriculum points out that in mathematics teaching, it is necessary to cultivate students’ sense of application and make students recognize that real life contains a great deal of mathematical information. Mathematics has a wide range of applications in the real world. When faced with practical problems, Try to use the learned knowledge and method to find a solution to the problem from the perspective of mathematics; in the face of new mathematical knowledge, it can actively look for its life background and explore its application value. “Solving Problems ” Teaching is especially important in the entire primary school, especially in senior grades, and it is both a key point and a difficult one. In the “problem-solving” teaching, we should guide students to master a variety of problem-solving ideas by analyzing the quantitative relationship, meanwhile teaching
