《义务教育数学课程标准》“第一学段”目标:能运用生活经验,对有关的数字信息作出解释,并初步学会用具体的数描述现实世界中的简单现象。要初步学会表达解决问题的大致过程和结果,归纳数学学习的过程。数学语言的简洁性、条理性、抽象性、精确性等学科特点,使数学语言表达能力培养成为数学学习的必然,数学语言表达能力也直接影响着学生分析、解决问题的能力。 “Compulsory Education Curriculum Standard” “First Semester ” Objective: To apply the life experience to explain the relevant digital information and to learn how to use specific numbers to describe the simple phenomena in the real world. To learn how to express the general process of solving the problem and the results, summarizing the process of mathematical learning. Mathematical language conciseness, orderliness, abstraction, accuracy and other disciplinary features make mathematical language expression ability to become a necessary mathematical learning, mathematical language ability to directly affect the ability of students to analyze and solve problems.
