What students learn

Apply the enlargement transformation to shapes with dynamic geometry software, and explain what changes and what stays the same.

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.
