直尺、三角板这两种学具是大家再熟悉不过的操作工具.在以往的考场上,这些学具主要是用来测量和作图的.在近几年的中考试卷中,这些学具却又呈现出不同的角色,成了一些中考数学试题的问题背景、操作工具、探究载体.学具的融入让“冰冷”的中考题透出一股灵气,勾画出一个个立意新颖、构思巧妙的数学模型.现就近年来中考试题中选取一些有代表性的以三角板、直尺为背景材料设计的数学问题,结合《平面图形的认识(一)》进行分类评析,与同学们分享. Ruler, set square these two kinds of learning tools are familiar tools to operate in the past examination room, these instruments are mainly used to measure and mapping in recent years in the examination papers, these learning tools are But also showed different roles, became some of the background of the math test questions, operating tools, to explore the carrier. The integration of learning tools so that the “cold” senior high school entrance examination questions revealed a Aura, outlined a novelty, the idea Clever mathematical model.Currently in the middle of the examination questions in the selection of some representative of the triangular plate, ruler as the background material design of mathematical problems, combined with “the understanding of plane graphics (a)” classification analysis, and classmates to share.
