Fourth, rulers. They are very important for drawing and measurement. We can choose rulers of different lengths to meet different needs. In addition, different types of rulers, such as straight rulers and triangle rulers, each have their own purposes. Straight rulers are mainly used to draw straight lines and measure lengths, while triangle rulers can be used to draw angles and assist in drawing.

Fifth, notebooks and sticky notes. They are good helpers for recording and learning. When selecting them, we should consider factors such as paper quality, thickness, and size. High-quality paper should have good writing performance and a long service life. Additionally, different colors and thicknesses of paper can also meet our different needs.
