《数学课程标准(2011年版)》指出:“通过义务教育阶段的数学学习,学生能获得适应社会生活和进一步发展所必需的数学的基础知识、基本技能、基本思想、基本活动经验。”“学会独立思考,体会数学的基本思想和思维方式。”由此可见,数学思想方法的渗透变得尤为重要。我们所使用的教材中,像数学概念、法则、公式、性质等知识都比较明显,而数学思想方法却隐涵在数学知识体系里,分散在各章节中。教师讲不讲,讲多讲少,随意性较大,也常常会因教学时间 The Mathematical Curriculum Standard (2011 Edition) states: “Through the mathematics study in the compulsory education phase, students can acquire the basic knowledge, basic skills, basic ideas and basic activities of mathematics necessary for social life and further development.” “ ”Learn to think independently and understand the basic thinking and thinking of mathematics." Thus, the penetration of mathematical thinking and methodology has become even more important. The materials we use, such as mathematical concepts, rules, formulas, nature and other knowledge are more obvious, and mathematical ideas and methods are hidden in the mathematical knowledge system, scattered in various chapters. Teachers do not speak, speak less, more random, but also often because of teaching time
