几何直观是指利用图形描述和分析数学问题,是《义务教育数学课程标准(2011版)》(以下简称《标准》)中的十个核心概念之一。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,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,我们应重视几何直观的培养。一、利用几何直观,帮助理解运算定理小学数学中的运算定律是小学阶段的重要内容,但学生在理解和
Geometric intuition refers to the use of graphics to describe and analyze mathematical problems, and is one of the ten core concepts in the Compulsory Education Curriculum Standard (2011) (hereinafter referred to as the “Standard”). With the help of geometric intuition, the complicated mathematical problems can be simplified and vivid, which can help to find solutions to the problems and predict the results. Geometry intuition can help students to understand mathematics intuitively and play an important role in the whole process of mathematics learning. We should pay attention to the cultivation of geometry and intuition. First, the use of geometric intuition, to help understand the theorem of operation The mathematical law of elementary mathematics is an important part of primary school, but students understand and
