Suggestion: 1. When learning mathematics, use graphics to express abstract concepts. For example, trigonometric function in mathematics can establish a simple coordinate system, draw a unit circle and a rectangular coordinate system, and the origin coincides with the circle, so that the relationship in trigonometric function can be given.

2. Let the students establish a court memory method, such as putting the items in the room in the form of pictures and giving their relative positions or coordinates, so that the students can repeatedly remember the items or models in the room, which can be props, mathematical formulas, words and so on. And can exercise their spatial thinking ability well.

3. In mathematics teaching, more three-dimensional space graphics and three-dimensional models are displayed, so that students can remember the three-dimensional model and define the fixed-point position in the model, which can also optimize spatial thinking.

4. Let students draw more coordinate systems, establish three-dimensional standard graphics, and give them by combining color with reality, which should help to optimize spatial thinking.
