1. In Tian Zi, it is necessary to keep the consistency and regularity of horizontal and vertical lines when writing numbers. The size of each cell should be the same, the numbers should be written in the middle of the cell, the size should be appropriate, the font should be standardized, the arrangement should be orderly, and they should be independent of each other, and they should not cross or overlap.

2. In Tian Zige, the spacing between numbers should also be consistent. Numbers should not be too close to each other, which will affect recognition, nor too far away, resulting in too many blanks and irregular appearance. The distance between numbers should be normal, with reasonable blank, not too crowded or scattered.

3. How to write the numbers 4 and 7? The number 4 needs to leave the bottom of the vertical bar at the bottom of the grid to prevent the vertical bar from exceeding the grid and causing confusion. The number 7 should be written parallel to the front horizontal line to avoid being too high or too low, which is different from other numbers in shape and is mistaken.

4. When using Tian Zi dot matrix for digital writing, it is necessary to keep the lines regular, the spacing reasonable, the font standard and the shape neat. This is not only beautiful, but also helps us to complete the mathematical calculation quickly and accurately.

5. As a common tool in Chinese teaching in primary schools, Tian Zige not only teaches us correct writing posture, but also includes beautiful, neat and standardized education courses. These beautiful habits and education will play an irreplaceable role in our future life.

Tian Zige is a very basic and simple tool, which is widely used in primary and secondary school students' writing, handwriting practice and mathematical operation. In Tian Zige, words should be written neatly, and every word should be written in the middle of the grid. The horizontal and vertical lines should be slightly tilted inward and the spacing should be appropriate. At the same time, when using Tian Zi lattice, we should also pay attention to the writing method of numbers 4 and 7 to avoid visual errors. Tian Zige's regular forms and writing norms are the basis for cultivating children's correct writing and standardized thinking.
