What technique can high school students use to improve their drawing accuracy?

Utilizing a grid system is a highly effective technique for high school students looking to improve their drawing accuracy. This method involves overlaying a grid of equal squares onto both a reference image and the drawing surface. By breaking down the image into manageable segments, students can focus on replicating the content of each square individually. This approach helps in maintaining proportion and scale, making it easier to capture the intricate details of the subject matter.

Additionally, the grid system encourages careful observation and comparison, allowing students to better understand the relationships between different elements of the drawing. This structured approach can enhance their ability to accurately depict a wide range of subjects, from still lifes to portraits, and fosters a deeper comprehension of spatial relationships in their artwork.
