Learning Olympic mathematics in primary schools has the following benefits for students:

1. Cultivate logical thinking ability: Olympic math problems often require students to make logical reasoning and analysis. By solving these problems, students can cultivate their logical thinking ability and improve their problem-solving ability.

2. Enhance the basic knowledge of mathematics: Olympic math problems usually involve some complex mathematical concepts and methods, and students need to apply all kinds of mathematical knowledge in the process of solving problems, so as to deepen their understanding and mastery of the basic knowledge of mathematics.

3. Cultivate patience and perseverance: Olympic math problems often require students to think and try repeatedly, which requires students to have patience and perseverance and be able to solve problems persistently.

4. Improve the spatial imagination: The concepts of graphics and geometry are often involved in Olympiad. Students need to solve problems through observation and imagination, thus improving their spatial imagination.

5. Cultivate teamwork spirit: Olympic math competitions are usually held in groups, and students need to work together to solve problems in teams, which is helpful to cultivate students' teamwork spirit and communication skills.

6. Enhance self-confidence: By participating in the Olympic Mathematics Competition and getting good grades, students can enhance their self-confidence and have a deeper understanding of their abilities and potentials.

In a word, learning Olympic mathematics in primary school can not only improve students' mathematics level, but also cultivate students' comprehensive qualities such as logical thinking ability, spatial imagination and teamwork spirit, which has a positive impact on students' all-round development.
