Where AC9M9M04 comes from and where it goes, for a student working below or above Year 9.

1. Year 8AC9M8M01solve problems involving the area and perimeter of irregular and composite shapes using appropriate units
2. Year 8AC9M8M02solve problems involving the volume and capacity of right prisms using appropriate units
3. Year 8AC9M8M03solve problems involving the circumference and area of a circle using formulas and appropriate units
4. Year 8AC9M8M04solve problems involving duration, including using 12- and 24-hour time across multiple time zones
5. Year 8AC9M8M05recognise and use rates to solve problems involving the comparison of 2 related quantities of different units of measure
6. Year 8AC9M8M06use Pythagoras’ theorem to solve problems involving the side lengths of right-angled triangles
7. Year 8AC9M8M07use mathematical modelling to solve practical problems involving ratios and rates, including financial contexts; formulate problems; interpret and communicate solutions in terms of the situation, reviewing the appropriateness of the model
