Abstract
This paper is primarily used for notebooks and other study materials by children and students. Instead of lines, this paper features dots at each vertex of a figure of adjacent equilateral triangles, with two rows of dots evenly spaced vertically and horizontally. For example, as shown in the reference diagram showing the paper in use, (1) the rhythmically spaced dots instead of lines make it easy to write letters and mathematical formulas. (2) It is easy to write horizontally offset text and timelines. (3) The evenly spaced dots make it easy to draw isometric projections and other diagrams, making it easy to learn three-dimensional and two-dimensional shapes. (4) The small number of dots makes it nearly blank, allowing for free-flowing creativity. (5) The dots are evenly spaced vertically and horizontally instead of lines, making it easy to write both vertically and horizontally. These features include:
