Properties of shape - Count vertices on 3D shapes - Worksheet

The educational worksheets provided are designed to enhance children's understanding of 3D shapes by focusing on counting vertices. A vertex is defined as a point where two or more edges meet on a 3D shape. To ensure accuracy and prevent overcounting, students are instructed to mark each vertex as they count. The worksheets highlight that the apex of a cone can also be described as a vertex. Through the use of a shape mat, students are encouraged to identify and name various 3D shapes and to sequence a number of shapes based on the quantity of their vertices, ranging from the fewest to the most.

Further exercises include filling out a table with the names of shapes alongside their corresponding number of edges, faces, and vertices. For instance, a triangular prism has 9 edges, 5 faces, and 6 vertices, while a cylinder has 2 edges, 3 faces, and no vertices. Children are tasked with ordering shapes such as the cylinder, cone, cuboid, cube, and square-based pyramid, based on their vertex count. Additionally, reasoning questions challenge students to consider whether statements about vertices and edges are true or false and to solve problems like identifying a shape with a specific number of vertices. This approach to learning combines fluency and precision with problem-solving skills to deepen students' geometric knowledge.
