Task goals
- Calculate the area or perimeter of a rectangle, triangle, parallelogram, trapezium, or circle from a realistic scenario.
- Convert between units of length (e.g. cm to m) before calculating an area, perimeter, or circumference, and recognise that area conversion factors are squared.
- Use a calculated area, perimeter, or circumference to find a quantity of material needed for a real task.
- Calculate the total cost of a quantity of material, rounding a discrete purchase (tins, rolls, sheets, packs) UP to the next whole item and money to the nearest cent.
- Compare two real options by total cost and/or value per unit area, and check whether each meets a stated constraint such as a budget or a free-delivery threshold.
- Write a short, numbers-based justification for a real-world measurement decision.
