At yesterday's parents' forum, some parents suggested that children's understanding of mathematical application problems is not strong. I thought about it over and over again afterwards. In primary school mathematics teaching, the application problem teaching plays an important role. Because of their young age, poor understanding and lack of real life experience, primary school students are gradually transitioning from concrete thinking in images to abstract logical thinking. Therefore, application problems are difficult for students to understand and master. Therefore, it is urgent to strengthen students' understanding ability. Recalling my own teaching, the summary is as follows: 1. Help students grasp the key words of application problems by intuitive means. The first step for primary school students to learn application problems is to understand keywords. I remember that when the first-grade pupils just entered school and learned simple application problems of addition and subtraction, they didn't know what a * * * was and what a remainder was, especially the same quantity. When teaching, I pay attention to choose some commonly used items such as knives and erasers for intuitive teaching to help them understand. For example, talk about subtraction application problems and demonstrate with learning tools: one * * * has three apples, and one has been taken away. How much is left? Let the students watch the demonstration. The equation is 3- 1 = 2, and then say that 3 represents a * * *, 1 "represents the number taken away, and 2 represents the remaining number; In an atmosphere full of interest, students unconsciously understand the meaning of * * * and what is left. When explaining the term "as much as possible", I first arrange three circles and three triangles on the magnetic blackboard, so that students can observe whether the number of circles and triangles is the same. Then explain that the same number is called the same number. Explaining mathematical keywords by intuitive means not only makes students learn vividly and understand thoroughly, but also makes them impressed, paving the way for students to solve application problems smoothly. Third, teach students the rules of solving application problems by intuitive means. 1. Look straight and distinguish the relationship. On the basis of grasping the key words of mathematics, the law is summarized: 1. Add the words * * *, and original; Subtraction is used for words such as difference and remainder. Students are good at grasping key words in solving problems in the future and have achieved good teaching results. In the teaching process of "The Times of Understanding", eight circular pieces of paper are discharged by the first group of teaching AIDS, and the number of triangular pieces of paper in the second group is twice as much as that of disks; In the second group, there are 16 disks in the first row, which is twice as many as the triangular pieces of paper in the second row. Ask the students to tell how many triangular pieces of paper are arranged in the second group, and then analyze two key sentences: the number of red flowers is three times that of yellow flowers, and the number of red balls is four times that of flower balls. Understand the meaning of multiples is several times. 2. Look straight and summarize the rules. Through practical analysis and comparison, the following laws are summarized: how many times to prove a number by multiplication exercises, and improving the teaching of application problems by intuitive means can cultivate students' skills and skills in calculating application problems; It is helpful for intensive reading and more practice. In unit time, there are many teaching contents, good results and high quality, which increases the density of classroom practice. Can complete the teaching task well and perfectly; It promotes the teaching of examples of mathematical application problems; At the same time, it also promotes the teaching of other subjects. Therefore, it is one of the effective ways to improve the teaching quality by using intuitive means to improve the teaching of application problems.
