Visually challenged students use raised-marked scales because they allow them to feel and read measurements through touch. These scales have raised lines or bumps that represent the units of length, such as centimeters or inches, so students can trace them with their fingers. This makes it possible for visually impaired students to measure objects accurately without needing to see the scale. Raised-marked scales are specially designed to provide tactile feedback, enabling better learning and understanding of measurements.
