Achievement objective NA6-2
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:
- extend powers to include integers and fractions.
Indicators
- Uses integer powers in solving problems.
- Uses number knowledge, with fractional powers, to find square and cube roots that generate rational solutions, for example: (4/9)^0.5=√(4/9)=2/3.
- Works with numbers in standard form and moves flexibly between standard form and ordinary form.
- Uses number knowledge and technology when solving problems.
- Makes links with solving equations NA6-5 and generalised properties of operations NA6-6.
- See key mathematical ideas on NZmaths.
Progression
NA 6-2 links to M7-6
Possible context elaborations
- Richter scale
- Exploring exponent rules using number
- Powers of powers
- Patterns of powers
- Exploring order of operations, for example, using four 4s to make the numbers 1 to 100.
Assessment for qualifications
