Cultivating mathematical thinking needs to start from the following aspects:

1. Cultivate interest: A strong interest in mathematics is the basis for cultivating mathematical thinking. Students' interest in mathematics can be stimulated by reading math stories and participating in math competitions.

2. Cultivate logical thinking: Mathematics is a rigorous discipline, which requires rigorous logical thinking ability. By solving logical problems and reasoning problems, students' logical thinking ability can be exercised.

3. Cultivate abstract thinking: Concepts and theorems in mathematics are often abstract, which requires students to have abstract thinking ability. Students' abstract thinking ability can be cultivated by solving abstract problems and mathematical modeling.

4. Cultivate spatial thinking: The relationship between geometry and space in mathematics requires students to have spatial thinking ability. We can cultivate students' spatial thinking ability by solving geometric problems and modeling solid geometry.

5. Cultivate innovative thinking: Mathematics is a developing subject, which requires students to have innovative thinking ability. We can cultivate students' innovative thinking ability by solving open problems and conducting mathematical inquiry.

6. Practice more: The cultivation of mathematical thinking needs a lot of practice. We can practice by doing math problems and participating in math competitions to improve students' mathematical thinking ability.

In short, the cultivation of mathematical thinking needs to start from many aspects. By cultivating interest, exercising logical thinking, abstract thinking, spatial thinking and innovative thinking, and doing a lot of exercises, students' mathematical thinking ability can be effectively improved.
