Achievement objective NA6-4
In a range of meaningful contexts, students will be engaged in thinking mathematically and statistically. They will solve problems and model situations that require them to:
- find optimal solutions, using numerical approaches.
Indicators
- Solves problems that can be modelled by a systematic approach, such as:
- making lists of possibilities and comparing
- constructing a table of values (trial and improvement).
- Finds optimal solutions, which are solutions that maximise or minimise a quantity while meeting the constraints of the situation.
- See
key mathematical ideas on NZmaths.

Possible context elaborations
- Find the dimensions of a paddock that has maximum area given a fixed perimeter (for example, set amount of fencing material).
-
Design a car park that fits the most cars and meets certain conditions, for example, each car has a fixed amount of space.
- Find the maximum volume of an open-topped box created from a sheet of A4 paper.
- Design a container of minimum surface area that holds items (for example, muesli bars, tennis balls, 330 ml liquid).
- Maximise profit from selling concert tickets where the price of the ticket depends on the number of seats sold.
- Find the shortest route (time or distance) from Hamilton to Palmerston North.
- Find the prism that has minimum surface area, given that the cross-section is square and the volume is 700cm3.
