一、从类型入手初中数学教材中出现的常见类型大致有:行程问题、工程问题、年龄问题、数字问题、利润问题、运输问题、发芽率、出勤率、及格率问题、配套问题、比例问题、储蓄问题、溶液问题、调配问题等等。教师在讲课的过程中要帮助学生分清是哪种类型的应用题,每种类型题数量之间有怎样的关系。二、从公式入手不同类型的应用题所应用的解题方法不同,所运用的公式也不同。所以教师在讲课的过程中一定要让学生把每种类型应用题的公式熟记于心,并能灵活运用。为了让学
First, starting from the type of junior high school mathematics textbooks appear generally common types are: travel problems, engineering problems, age issues, digital issues, profit issues, transportation issues, germination, attendance, passing rate, supporting issues, Savings problems, solution problems, deployment problems and more. Teachers in the process of lectures to help students distinguish between what type of application questions, the amount of each type of question what kind of relationship. Second, from the formula to start different types of problem-solving application of the problem-solving methods are different, the formula used is also different. Therefore, teachers in the process of lectures must allow students to formulate formulas for each type of application in mind, and can be flexible use. To make learning
