Teaching guide

What students learn

Solve practical problems involving the perimeter and area of regular and irregular shapes using suitable metric units.

Perimeter = 5 + 3 + 5 + 3 = 16 units

How to teach it

Sort and name 2D and 3D shapes by their properties (sides, angles, faces), then build up to perimeter (add the sides) and area (cover with unit squares).

Worked example

Find the area.

Answer: 128

Why: 16 × 8 = 128

Generated and checked in code, so it is correct.

Watch out for

Confusing perimeter and area, and judging a shape by its orientation rather than its properties.
