Mathematics
AK worked out how much ink was needed to create 63 A5 booklets using A4 paper. This required connecting the number of booklets to the amount of printing and considering how paper size relates to the planned output. AK applied practical numerical reasoning to estimate or calculate a resource requirement for a specific production task. The activity showed how mathematics can support planning and decision-making in everyday contexts.
Design and Technologies
AK considered the materials and consumable resources involved in producing a batch of A5 booklets from A4 paper. By relating the booklet quantity to the ink requirement, AK engaged with a practical production-planning problem. The task connected choices about format and resources with the needs of making a finished product. It also highlighted the value of calculating supplies before beginning a production task.
Tips
Tips Extend the task by having AK compare different print layouts, such as printing one or more booklet pages on each sheet, and explain how the layout affects paper use. Use a printer’s actual ink-coverage estimate or a sample print to compare predicted and observed ink consumption, then discuss why the results may differ. Invite AK to create a simple cost plan for producing the booklets, including paper and ink, and compare options such as colour versus black-and-white printing. Finish with a brief design review in which AK explains which layout best balances readability, material use and cost.

Learning Standards
- Australian Curriculum v9.0 — Mathematics, AC9M10N01: The activity involved calculating a practical quantity and can connect to considering how approximations affect repeated calculations, where estimates were used.
- Australian Curriculum v9.0 — Mathematics, AC9M10M05: The task connected quantities and paper formats in a real-world production context; this is a relevant link to mathematical modelling involving proportion and scaling.
