Advantages of primary school mathematics examination:
1. Test learning effect: Math test can effectively test students' learning effect. Through the examination, students can know what they have mastered well and what they need to improve. At the same time, test scores can also reflect students' learning methods and attitudes, thus helping them to better adjust their learning strategies.
2. Stimulate learning motivation: Math exams can stimulate students' learning motivation. Examination is a process of evaluation and comparison. Students can know their ranking and advantages through exams, thus stimulating their sense of competition and enterprise. At the same time, exams can also make students experience the fun and sense of achievement in learning, thus stimulating their interest and motivation in learning.
3. Cultivate problem-solving ability: Mathematics examination can cultivate students' problem-solving ability. Different types of problems will be encountered in the exam, and students need to learn to analyze problems, find laws and solve these problems by formulas. This problem-solving ability is not only important in mathematics learning, but also important in daily life and future work.
