What Are Sides, Vertices, Edges, and Faces?
Let's explore the parts that make up shapes!
Every shape is made of special parts with fun names. Let's meet them:
Sides - The straight lines that make the outline of a shape
Vertices (corners) - The points where sides meet
Edges - The lines where two faces meet in 3D shapes
Faces - The flat surfaces of 3D shapes
Let's Compare Some Shapes!

Vertices: 4
Edges: 0 (it's flat!)
Faces: 1
Cube

Parent Tips 🌟
- Shape Hunt: Go on a shape hunt around your house! Find objects and count their sides, vertices, edges, and faces together.
- Playdough Shapes: Use playdough to create 3D shapes and count their parts. Rolling "snakes" can help make edges!
- Everyday Math: Point out shapes in everyday objects - cereal boxes are rectangular prisms, balls are spheres, and dice are cubes.
