因为用数学建模解应用问题最能让学生学会用数学的思维方式去观察和分析问题,能很好地增强其应用数学的意识,能有效地培养其解决实际问题的能力。因此,在各类竞赛和中考中,数学建模类考题的出现频度一直居于高位。强化学生应用数学建模解应用问题的训练,是提高学生数学能力的有效方法。1借助方程建模解题例1某地区两次升级电话号码,第一次由六位升为七位,方法是在首位数字和第二位数字之间加上
Because using mathematical modeling solution to the most practical problems allows students to learn to use mathematical way of thinking to observe and analyze problems, can well enhance their awareness of applied mathematics, can effectively develop their ability to solve practical problems. Therefore, in all kinds of competitions and senior high school exams, the frequency of the questions of mathematical modeling has always been at a high level. Strengthening students ’application of mathematical modeling solution to the application of training is an effective way to improve students’ mathematical abilities. 1 Equation Modeling Problem Example 1 In a certain area, the telephone number is upgraded twice, the first time from six to seven, by adding between the first digit and the second digit
