# Units 3 and 4

## Performance criteria

The following performance criteria have been developed to assist teachers in the assessment of School Assessed Coursework for Mathematical Methods Units 3 and 4. The performance criteria for the Application task and for the two modelling or problem-solving tasks relate the mark weightings for the outcomes to these assessment tasks and provide a basis for decision about level of achievement.

### Unit 3

Mark range Criterion
0 - 6 Appropriate selection and effective use of technology

Relevant and appropriate selection and use of technology, or a functionality of the selected technology for the mathematical context being considered. Distinction between exact and approximate results produced by technology, and interpretation of these results to a required accuracy.
