Teaching guide

What students learn

Establish the formula for the area of a rectangle and use it to solve practical problems.

Area = 4 × 3 = 12 square 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 perimeter.

Answer: 50

Why: 2 × (14 + 11) = 50

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.
