2D and 3D Shapes!
2D = flat (circle, square, triangle); 3D = solid (sphere, cube, cylinder).
Learning Objective
Kids learn 2D shapes are flat and 3D shapes are solid, and that 3D shapes have faces, edges, and vertices.
What You'll Learn
- 2D = flat (circle, square, triangle); 3D = solid (sphere, cube, cylinder).
- 3D shapes have faces, edges, and vertices.
- A cube = 6 faces, 12 edges, 8 corners.
- Real objects match 3D shapes (ball, can, dice).
Words to Know
- Two-dimensional (2D)
- A flat shape you can draw on paper!
- A circle is a 2D shape.
- Three-dimensional (3D)
- A solid shape you can hold!
- A ball (sphere) is a 3D shape.
- Face
- A flat side of a 3D shape!
- A cube has 6 faces.
- Vertex (corner)
- A pointy spot where edges meet!
- A cube has 8 vertices.
