应用性问题大多来源于生活,涉及面广,题型比较灵活．《数学课程标准》强调从学生已有的生活经验出发,让学生亲身经历将实际问题抽象成数学模型来解决并应用的过程,进而使学生在获得对数学理解的同时,在思维能力、情感态度与价值观等多方面得到进步和发展．例1小杰到学校食堂买饭,看到A、B两窗口前面排队的人一样多(设为a
Most of the application problems come from life, involve a wide range of questions, more flexible types of questions. The “Mathematics Curriculum Standards” emphasizes starting from the students’ existing life experiences, allowing students to personally experience the process of abstracting practical problems into mathematical models to solve and apply them, so that students can gain understanding of mathematics while at the same time thinking ability and emotional attitude. With many values and other aspects of progress and development. Example 1 Xiaojie went to the school cafeteria to buy food and saw as many people lined up in front of the A and B windows (set to a
