Teaching guide
What students learn
Divide shapes into equal areas and name each part as a unit fraction of the whole.
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.
