随着新一轮课程改革的不断深入,学生在获得基本数学知识和应用技能的同时,更注重构建基本的数学思想,让学生积累基本的数学活动经验。数学概念是客观现实中数量关系和空间形式的本质属性在人脑中的反映。只有很好的理解和掌握数学概念,才能将它在解决实际数学问题时运用自如。由于数学概念具有抽象性,而小学生的思维正处在由具体形象思维为主向抽象逻辑思维为主的过渡阶段,因此,要顺利发展小学数学概念,必须从小学生年龄段的心理特征、
Along with the deepening of the new round of curriculum reform, students gain basic mathematics knowledge and applied skills while paying more attention to building up basic mathematical thinking so that students can accumulate basic experience in mathematical activities. Mathematical concepts are the reflection of the essential attributes of quantitative relations and spatial forms in the human mind in objective reality. Only a good understanding and mastery of mathematical concepts, it can be used in solving practical mathematical problems freely. Because the concept of mathematics is abstract, and pupils ’thinking is in the transitional phase mainly from the concrete image thinking to the abstract logical thinking, so to develop the concept of mathematics in primary school smoothly, we must analyze the psychological characteristics of pupils’ age,
