A budget can add up on paper and still feel tight if several payments land before the next payday. This activity makes timing visible. It uses made-up figures for learning, not current prices or a recommended household budget. Teams can work with paper, a blank calendar and a calculator.
The scenario
A fictional household receives $1,500 after tax on Day 1 and has these payments during the next 14 days:
- Day 1: rent, $520
- Day 2: groceries, $160
- Day 4: power, $130
- Day 5: transport, $85
- Day 8: phone, $50
- Day 9: groceries, $155
- Day 11: insurance, $180
- Day 13: school trip, $45
- Day 14: transport, $85
The listed costs total $1,410, leaving $90 from the fictional $1,500. The activity question is not only “Is the total under income?” It is also “How much remains after each payment, and what needs to stay available for the second week?” The figures leave out many real household costs, so a real plan would need a fuller list.
Round one: map the running balance
Give each team a blank 14-day timeline. Start with $1,500 on Day 1, then subtract each cost on its due date. After rent and the first groceries, the running balance is $820. After the Day 5 transport cost, it is $605. After the second groceries payment on Day 9, it is $400. Continue to the final Day 14 payment and check whether the arithmetic ends at $90.
Now ask teams to circle every point when a payment is due and underline the amount that must remain for the later dates. Can they explain why treating the full $820 after Day 2 as “spare” money would be a mistake? Invite students to use different colours for already-committed money and money not yet assigned.
Round two: draw a curveball
Give each team a surprise card: a $100 school-shoe purchase on Day 10. The list now totals $1,510, which is $10 more than the available $1,500. Teams must show the gap and name a sensible next step. Possibilities include checking whether the purchase can wait, finding out whether an existing support option applies, or contacting a biller early to ask about arrangements. Do not assume a biller must move a due date, and do not frame borrowing as the automatic fix.
For a final discussion, ask what information the household would need before acting: is the amount exact, is the payment date fixed, are there other essential costs missing, and who can safely help them check? Sorted’s budgeting guide recommends listing after-tax income and expenses for a chosen period, then comparing the totals. This game adds dates to that process so the class can see how cash flow unfolds.
Keep the conversation about the fictional plan. Students should not be asked to disclose their family’s income, bills or money stress. The goal is to practise the arithmetic, spot timing pinch-points and explain trade-offs without blame.
FAQs
Are the dollar amounts real prices?
No. Every amount in the scenario is invented for the activity and should not be used as a current price guide.
How much do the listed payments total?
They total $1,410, leaving $90 from the fictional $1,500 income before any costs the scenario omits.
Why use a running balance?
It shows how much remains after each dated payment, rather than only showing the final total.
What happens when the $100 surprise is added?
The listed total becomes $1,510, which is $10 more than the fictional income. Teams should identify the gap before proposing a response.
Should students share their family budgets?
No. The exercise uses a fictional scenario so students can practise without disclosing private household information.
Is contacting a biller guaranteed to change a due date?
No. The activity only suggests asking what options may be available; any arrangement depends on the provider and circumstances.
