The invention provides an automatic limit line forming circular grid writing method, relates to the technical field of Chinese character writing training of primary and secondary school students, and aims to solve the core pain points that the
font size is difficult to control during writing of the primary and secondary school students and the
handwriting is easy to
skew when being switched to a transverse line / blank paper. The core of the method is a round grid composed of an outer circle with the
diameter of 6 mm and a central inner square with the side length of 2 mm, the round grid is matched with a standard composition grid with the
diameter of 8 mm, and a blank space with the
diameter of 1 mm is formed; the method is realized through four-step training of practicing a
single character by a single round grid, practicing coherent writing by a row of round grids, alternately transitioning round grids and transverse lines, and challenging a
reference line at the top of blank paper, and is combined with a special exercise book, an indentation ruler or light-
color printing. By means of the method, the paper surface neatness of composition grid writing can be immediately improved, the students can form
muscle memory through training of the psychological datum line, finally, the students can also write neatly on the blank paper, and the method is suitable for the students of the third grade and above of the primary school and is a scientific and practical writing training
system.
