新课程标准标要求中考重点考察学生的数学应用意识.“格点问题”能很好的承担这一精神,考查了学生对图形的观察力和对数学规律的探究能力,突出了“数形结合”的思想方法,所以“格点问题”在中考中每年都会出现,从第一次出现就给人耳目一新的感觉开始,“格点问题”在网格背景下作为一个平台综合了勾股定理、平移、旋转、三角函数、相似等多个知识点,融合了数量关系和位置关系,将初中数学的代数和几何知识很自然的融合一体.
The new curriculum standards require students to focus on the mathematical test application of mathematical knowledge. “Grid ” can be a good undertaking of this spirit, examining students’ ability to observe the graphics and mathematical rules of inquiry, highlighting the “ ”Lattice “ problem appears every year in the senior high school entrance examination, starting from the first appearance gives a refreshing feeling began, ”lattice problem " in the context of the grid as A platform synthesizes multiple knowledge points such as Pythagorean theorem, translation, rotation, trigonometric function, similarity and so on. It integrates the quantitative relationship and the positional relationship, and integrates algebra and geometry knowledge of junior middle school mathematics naturally.
