Fascinating Fact:
The Earth is not a perfect sphere, it is slightly squashed at the poles, a three dimensional shape called an oblate spheroid.
In 11 Plus Maths, pupils explore both 2D and 3D shapes, learning their names, properties, and real-life examples. Understanding shapes supports geometry, design, and spatial reasoning skills.
Key Terms
- Face: A flat or curved surface on a 3D shape, such as the side of a cube or cylinder.
- Edge: The line where two faces meet on a 3D shape.
- Vertex: A corner point where edges meet, also called a corner.

Frequently Asked Questions (Click to see answers)
What are examples of 3D shapes in everyday life?
Examples include a football (sphere), a dice (cube), a tin can (cylinder), and a pyramid (used in ancient architecture).
What is the difference between 2D and 3D shapes?
2D shapes are flat and have only length and width, while 3D shapes have depth as well, making them solid and real-world objects.
Why is the Earth called an oblate spheroid?
The Earth bulges slightly at the equator and flattens at the poles due to its rotation, creating an oblate spheroid shape rather than a perfect sphere.
