新课程强调培养学生的数学意识与能力,作为数学教师就应依据教材,注重学生基本活动经验,挖掘素材,开展学生数学实验,增强学生主观能动性,是非常重要的.笔者认为:初中数学中的矩形折纸问题蕴含着很丰富的内容,动手操作、直观观察、知识应用,以及数学合情推理与逻辑推理,具有很好的教育教学功能.本文对这方面的知识和题型作归纳和分析,以期有助于读者朋友.一、数学实验前应具备的知识1.矩形的性质
The new curriculum emphasizes cultivating students ’mathematical awareness and ability, as a teacher of mathematics, it is very important that we should base on teaching materials, pay attention to students’ basic activity experience, dig material, carry out students ’mathematical experiment and enhance students’ subjective initiative.I think: in junior middle school mathematics The problem of rectangular origami contains a wealth of content, hands-on operation, visual observation, knowledge application, as well as mathematics reasoning and logical reasoning, has a good education and teaching function.This paper induces and analyzes the knowledge and the type of questions, In order to help readers friends. First, the mathematics should have the knowledge before the experiment 1. The nature of the rectangle
