图形以其直观的形式为人们所容易接受,给人们带来了无穷无尽的直觉源泉,也为研究数学和解决问题提供了工具。几何直观是北师版教材(2011年版)中新增的核心概念,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,有助于解决问题的思路,预测结果。几何直观可以帮助学生直观理解数学,在整个数学学习过程中都发挥着重要作用。”北师版教材四年级下册第三单元《小数乘法》中
Graphics are easily accepted by people in their intuitive form, giving people an endless source of intuition and providing tools for studying mathematics and solving problems. Geometrical visualization is the core concept added in the textbook of the 2011 edition of the Beijing Normal University, which mainly refers to the use of graphical description and analysis of problems, the use of geometric intuition can be complex mathematical problems become concise image, help solve the problem Ideas, forecasting results. Geometrical intuition can help students intuitive understanding of mathematics, mathematics learning throughout the entire process has played an important role. “The third division of the fourth edition of the textbook of the North division” fractional multiplication "
