This math topic focuses on identifying and counting the edges of various 3D shapes. It serves as an introductory exercise into the broader area of 3D shape classification within geometry. The problems each depict a different 3D shape and ask students to determine the total number of edges. Multiple choice answers are provided for each question. This topic aims to enhance students' visual-spatial understanding and their ability to analyze three-dimensional geometric figures.
