How to improve students' problem-solving ability in primary school mathematics teaching
NCSM defines problem solving as the process of applying previously acquired knowledge to new and unfamiliar situations. The application of this concept in solving mathematical problems means that students can flexibly apply their existing mathematical knowledge and methods to solving problems in mathematics and real life. This ability to solve mathematical problems is an important symbol of students' mathematical literacy. Primary school students are limited by age, and their knowledge accumulation, life experience and social practice are not rich. How can we cultivate their ability to solve mathematical problems?

First, cultivate problem awareness-be good at asking questions

The ancients said, "Learning comes from thinking, and thinking comes from doubt." Cultivating problem consciousness is to encourage students to question; Encourage students to have their own unique views; Encourage students to ask valuable questions. In the teaching process, students should be allowed to ask questions at any time, and their questioning behavior, skeptical spirit and critical spirit should be praised and encouraged at any time, so that they can dare to ask questions and be good at asking questions.

Second, learn to correctly examine questions-accurate analysis

As we all know, "understanding the meaning of the topic is equivalent to doing half of the topic." The difficulty of solving a problem is determined by the plot of the problem and the quantitative relationship. If you want to solve a math problem successfully, you must carefully examine the problem. The purpose of the exam is to let students understand the meaning of the question, that is, to understand the plot part of the question, to know what the question is about, what happened, what conditions are known, what questions are required, and so on. On this basis, according to some key words in the topic, the quantitative relationship in the topic is further analyzed. In the teaching process, I summed up the five-step method of "reading, watching, circling, thinking and calculating", namely
