近年来各地的中考,无论是课改卷还是非课改卷．都有用一元一次方程来解决实际生活中问题的题型．这类题时代气息浓．与生活息息相关．让同学们真正体会到了数学的应用价值．充分体现了“人人学有价值的数学”的新课程理念．这类问题既是同学们学习的重点,又是一个难点,其实,解决这类问题的关键是结合生活经验建立适当的数学模型．下面举例进行说明．供同学们学习时参考．
In recent years, all local examinations, whether it is the curriculum reform or non-currency reform. There is an equation that solves real-life problems with a one-dimensional equation. The age of such questions is strong. Closely related to life. Let students really understand the value of mathematics application. Fully embodies the new curriculum idea of “Everyone learns valuable mathematics”. This kind of problem is not only the focus of the students’ learning, but also a difficult point. In fact, the key to solving this kind of problem is to establish an appropriate mathematical model based on life experience. The following example illustrates. Reference for students when learning.
