This math skill involves identifying and counting the faces, edges, and vertices of a 3D shape. A face is described as a flat side, excluding rounded sides; an edge as the line between two faces; and a vertex as the corner where edges meet.

Identify and count faces, edges, and vertices
Test your understanding of identify faces, edges, and vertices by practicing it! Work through the below exercises to use it in practice.
🎙️
Count how many faces, edges, and vertices this shape had
🎙️
A face is a flat side. Rounded sides are usually not counted as faces.
🎙️
An edge is the line between two sides.
🎙️
A vertex, or if plural, vertices, is a corner where edges come together
🎙️
Counting our faces, we have 6, like the number of sides of a dice
🎙️
For edges, there are 4 on top, 4 on the vertical sides, and 4 on the bottom
🎙️
There are 8 vertices, 4 on top, and 4 on the bottom
