Teaching guide

What students learn

Understand area as the amount of square units needed to cover a flat shape with no gaps or overlaps.

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

Rectangle 2 cm by 15 cm. Area = ___ sq cm

Answer: 30

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.
