Identify 3D shapes and describe their faces, edges and vertices
A cube, a ball and a can are solid (3D) shapes — describe each one by its faces (flat or curved), its edges, and its vertices (corner points).

Kavi's Solid Shape Hunt 📦
Kavi picks up a dice 🎲. "This is a cube — a solid (3D) shape I can hold! It has flat faces I could paint, straight edges where two faces meet, and pointy vertices (corners)." Then Kavi rolls a ball ⚽. "A sphere is round all over — one curved surface, no flat faces and no corners!" Kavi hoots: "Let's name solid shapes and describe their faces, edges and vertices!"

What your child will learn
1The three parts of a solid shapeA solid (3D) shape is one you can hold — like a box or a ball. We describe one by three parts. Look at this cube 🎲 and tap each part to meet it.
2Count the parts: cube and sphereNot every solid shape has flat faces. Tap each card to compare a cube 🎲 with a sphere ⚽.
3Flat faces only, or a curved surface?
🔍
A peek inside
Kavi holds a dice 🎲, which is a cube. How many faces, edges and vertices does it have?
6 flat square faces · 12 straight edges where faces meet · 8 vertices (corners)
Try this at home: How many faces does a cube have?
