The mathematics key learning area is organised around the interaction of three content strands and four proficiency strands.
The content strands are: number and algebra, measurement and geometry, and statistics and probability.
They describe what is to be taught and learnt.
The proficiency strands are understanding, fluency, problem solving, and reasoning. They describe how content is explored or developed, that is, the thinking and doing of mathematics. They provide the language to build in the developmental aspects of the learning of mathematics and have been incorporated into the content descriptions of the three content strands described above.
