新课标在总体目标中明确提出要使学生“经历运用数学符号和图形描述现实世界的过程,建立初步的数感和符号感,发展抽象思维”,在中考题中有意设置问题,检测考生的数感状态是2004年江西(包括南昌)中考卷的一道风景线.一、理解数的意义理解数的意义是同学们学习数学课程的重要任务 The new curriculum standard clearly stated in the overall goal that students should “experience the process of using mathematical symbols and graphs to describe the real world, establish a preliminary sense of numbers and symbols, and develop abstract thinking,” and deliberately set questions in the examination questions to detect the candidates’ The number sense state is a scenery line in the 2004 Jiangxi (including Nanchang) examination paper. First, understand the significance of numbers Understanding the meaning of numbers is an important task for students to learn mathematics courses.
