几何直观是数学新课程标准里提出的十个核心概念之一,是借助于见到的或想到的几何图形的形象关系产生对数量关系的直接感知。本文将结合苏教版六年级下册《圆柱的体积》谈一下学生几何直观能力的培养。一、几何直观的内涵数学新课程标准提出几何直观主要是指利用图形描述和分析问题,借助它可以把复杂的数学问题变得简明、形象,有助于探索解决问题的思路,预测结果。小学生的思维水平正处于具体运算阶段向形式
Geometrical intuition is one of the ten core concepts proposed in the new mathematics curriculum standard, which is the direct perception of the quantitative relationship by virtue of the image relationship of the geometrical figure seen or thought of. This article will be combined with the Sujiao version of the sixth grade volume “cylindrical volume” talk about students' ability to develop geometric intuition. First, the geometry of intuitive connotation Mathematics new curriculum standards put forward the geometric intuition mainly refers to the use of graphics to describe and analyze problems, with the help of it to complex mathematical problems become concise, the image helps to explore ideas to solve the problem, predict the results. The level of thinking of primary school students is in the concrete stage of computing
