1. Cultivate mathematical thinking: mathematical thinking is the key to solving problems. In primary school mathematics teaching, we should pay attention to cultivating students' mathematical thinking, including the ability of observation, comparison, analysis, synthesis, abstraction and generalization. The cultivation of these abilities requires teachers to guide students to actively participate in thinking in the classroom and encourage students to actively discover, ask and solve problems.

2. Mastering basic knowledge: Basic knowledge of primary school mathematics is the cornerstone of solving problems. Students need to master the basic knowledge of mathematical concepts, formulas and theorems in order to solve problems better. At the same time, teachers can help students consolidate basic knowledge through classroom teaching, practice and counseling.

3. Strengthen problem-solving strategies: problem-solving strategies are the key to solving problems. In primary school mathematics teaching, teachers need to teach students some basic problem-solving strategies, such as reverse thinking, combination of numbers and shapes, transformation and so on. At the same time, we should also guide students to learn to analyze problems and think about ways to solve them from different angles.

4. Encourage practice: Practice is an effective way to solve problems. In primary school mathematics teaching, teachers can help students better understand mathematics knowledge and improve their ability to solve problems by letting them operate and participate in practical activities.

5. Cultivate good habits: Good study habits are the guarantee to solve problems. Teachers need to guide students to develop good study habits, such as careful examination of questions, diligent thinking and independent completion of homework. These habits help students solve problems better and improve their learning effect.

Suggestions on improving the problem-solving ability of primary school mathematics;

1. Establish a mathematical model: A mathematical model is a tool to solve problems. In primary school mathematics teaching, teachers can guide students to build mathematical models, such as expressing mathematical problems through charts, images and equations, to help students better understand the problems and find solutions.

2. Pay attention to the diversity of problem-solving strategies: different problems need different solutions. In primary school mathematics teaching, teachers should pay attention to guiding students to explore a variety of problem-solving methods, such as reverse thinking, combination of numbers and shapes, transformation and so on. To cultivate students' thinking flexibility and innovation ability.

3. Strengthen the reflection on the problem-solving process: reflection is the key to improve the problem-solving ability. In primary school mathematics teaching, teachers need to guide students to reflect on the process of solving problems, analyze the reasons for success or failure, and sum up experiences and lessons in order to better deal with similar problems.

4. Stimulate students' interest in mathematics: interest is the driving force of learning. In primary school mathematics teaching, teachers can stimulate students' interest in learning through games, competitions and practical applications, so that students can feel the interest and practicality of mathematics and improve their enthusiasm and initiative in solving problems.

5. Encourage students to study cooperatively: Cooperative learning is an effective way to improve problem-solving ability. In primary school mathematics teaching, teachers can organize students to carry out cooperative learning such as group discussion and collective wisdom, so that students can solve problems together in mutual exchange and learning, and promote each other's growth and improvement.
