Teaching guide

What students learn

Use formulas and suitable units to solve problems about the circumference and area of a circle.

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

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.
