This math topic focuses on calculating the perimeter of irregular shapes on a grid. Each question provides a graphic of an irregular shape formed with 1x1 square grids, and students are tasked with determining the perimeter by counting the exposed edges of the squares that make up the shape. The problems are multiple-choice, providing various options for each shape's perimeter, enhancing the students' ability to visually assess and compute the perimeter in a structured format. This is part of a broader introductory unit on understanding perimeters.
