动手实践、自主探索、合作交流是学习数学的重要方式,通过独立操作探究,发展思维能力,加深理解相关的数学知识,增进应用数学的自信心.近年出现的体现新课程精神的操作探究题,已成为各地中考命题的热点,其形式多样,题材丰富,可操作性强,诸如利用几何图形的变换进行探究,利用工具(直尺、三角尺、量角器等)的变换进行探究,把图形或纸片剪、拼、割、补进行探究,利用尺规作图
Through hands-on practice, independent exploration, cooperation and exchange is an important way to learn mathematics, through independent operation to explore and develop thinking skills, deepen understanding of related mathematical knowledge, improve the self-confidence of applied mathematics.In recent years, reflecting the operation of the new curriculum spirit, Has become a hot topic in the school entrance examination throughout the various forms, topics rich, maneuverability, such as the use of geometric transformation to explore, the use of tools (ruler, ruler, protractor, etc.) to explore the transformation, the graphics or paper Shear, fight, cut, make up to explore the use of ruler to map
