《数学课程标准(2011版)》中提出的十个核心概念中,“几何直观”是重新修订时新增的重要理念。借助几何直观可以把复杂的数学问题变得简单、形象,有助于探索解决问题的思路,预测结果。一、借助几何直观,建立数学概念小学生通常对抽象的数概念难理解,认识数教学以理解数的意义为重点,但是数又是抽象的,在教学中往往借助简单的图形或示意图帮助学生在直观
Of the ten core concepts presented in the Mathematics Curriculum Standard (2011 Edition), Geometry Intuitive is an important addition to the revisions. With the help of geometric intuition, complex mathematical problems can be simplified and imaged, which can help to explore the solutions to problems and predict the results. First, the use of geometric intuition, the establishment of mathematical concepts Pupils usually difficult to understand the concept of number, knowledge of the number of teaching to understand the significance of the number of focus, but the number is abstract, often in teaching with a simple graphic or schematic to help students in Intuitive
