《数学课程标准》指出:“几何直观主要是指利用图形描述和分析问题”。借助几何直观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和预测结果。几何直观可以帮助学生直观地理解数学,在整个数学学习过程中都发挥着重要作用。著名数学家徐利治也有过对几何直观的描述:“几何直观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。”也有学者这么描 “Mathematical Curriculum Standards” pointed out: “Geometric intuition mainly refers to the use of graphics to describe and analyze the problem ”. With the help of geometric intuition, complicated mathematical problems can be simplified and imaged, which can help to explore the solutions to problems and predict the results. Geometrical intuition can help students to understand mathematics intuitively and play an important role in the whole process of mathematics learning. The well-known mathematician Xu Lizhi has also described the geometric intuition: “Geometric intuition is based on the visual relationship seen or thought of geometry, resulting in direct perception of the relationship between quantity ” Some scholars have such a description
