Core Skills Analysis
Math
- Tiffany used addition and subtraction to total sales and reconcile the cash drawer, strengthening mental arithmetic and place‑value understanding (ACMA154).
- She performed multiplication and division when calculating change for customers, applying the concepts of rates and ratios in real‑world contexts (ACMMG143).
- By interpreting pay entitlements on the Fair Work website, Tiffany worked with percentages, converting hourly rates to weekly earnings and understanding linear relationships (ACMS161).
- Setting up a superannuation account required Tiffany to calculate a contribution percentage of her wages, reinforcing proportional reasoning and budgeting skills (ACMS165).
Tips
To deepen Tiffany's financial math skills, have her keep a weekly earnings log where she records gross pay, tax withheld, super contributions, and net take‑home pay, then graph the trends over a month. Next, introduce a mock “restaurant budget” project: she must allocate her earnings to categories such as food, transport, savings, and entertainment, using percentages to plan and adjust the budget. Bring in real‑world data by comparing her calculated entitlements with actual pay slips from the Fair Work website, encouraging her to spot discrepancies and ask questions. Finally, set up a role‑play cash‑register scenario where Tiffany practices making change for various transaction amounts, reinforcing quick mental calculations and error‑checking strategies.
