Count and Compare Sides, Edges, Faces, and Vertices

Exploring the building blocks of shapes in 2D and 3D!

Understanding Shape Properties

Every shape has special features we can count and compare!
In 2D shapes, we count sides (edges) and corners (vertices). In 3D shapes, we also count faces - the flat surfaces that make up the shape. Let's learn how to identify and count these important features!

Counting Shape Features

1️⃣ Sides/Edges: The straight lines that form the shape's outline

2️⃣ Vertices: The points where edges meet (corners)

3️⃣ Faces: Flat surfaces (only in 3D shapes)

Parent Tips 🌟

  • Shape Hunt: Go on a shape hunt around your home and count sides/edges, corners, and faces of objects you find.
  • Building Challenge: Use building blocks or toothpicks and marshmallows to create shapes and count their features together.
  • Daily Objects: Compare everyday items - "Does the cereal box have more edges than your Rubik's cube?" to make learning practical.
