网格是我们从小就熟悉的图形,在网格中研究格点图形,具有很强的可操作性,是近几年中考的热点问题,能较好的考查大家的识图、分析、归纳、想象、动手操作、直觉推理能力和问题探究的能力.格点问题以网格为平台综合了坐标、变换、概率、三角函数、相似等多个知识点,融合了数量关系和位置关系,将初中数学中的代数和几何知识很自然的融合一体,让大家“在玩中学,在学中思,在思
Grid is familiar to us from the beginning of the graphics, lattice grid in the study of graphics, has a strong maneuverability in recent years, the examination of the hot issues, can better examine everyone’s knowledge map, analyze, summarize, Imagination, hands-on operation, intuitionistic reasoning ability and question exploration ability.Grid problem combines multiple knowledge points such as coordinates, transformation, probability, trigonometric function, similarity and so on on the grid as a platform, combines the quantitative relationship and the positional relationship, Mathematical algebra and geometric knowledge is a natural integration, so that everyone ”playing secondary school, learning in thinking, thinking
