This topic focuses on measuring the lengths of line segments on a grid composed of 1x1 squares. The problems involve identifying line segments of specific lengths such as 2, 3, 4, and 5 units. Each problem provides two visual options for the students to examine and decide which line segment accurately represents the length described. This set of problems serves as an introductory exercise for understanding the concept of perimeter related to irregular shapes on a grid.
