Immediate/future financial plans | Year 5

01 / LEARN

The idea, step by step

Plan before spending

An immediate plan concerns money you have now. List available money and agreed costs. Subtract those costs to find what is left. The leftover money may be saved, spent on another item or kept for an unexpected cost.

A budget does not create extra money. If costs are too high, change the quantity, find another suitable item, or wait. More than one spending plan may be reasonable.

Connect today with a future goal

Start with savings already held. Add the amount that can really be saved each week, not necessarily all the money received. A table can show how the total grows.

Compare the total with the target price and deadline. State assumptions, such as saving the same amount each week. Check the plan again if prices, income or spending change.

A common trap

Treat all income as savings when some is already planned for spending.

Instead: Subtract planned spending first. Use the amount kept in the savings calculation.

02 / WORKED EXAMPLES

See the thinking

Example 1

Money left today

A club has 48 dollars. It will spend 19 dollars on paper and 12 dollars on glue. How much remains?

Costs: $19 + 12 = 31$ dollars.
Remaining: $48 - 31 = 17$ dollars.
Check: $31 + 17 = 48$ .

17 dollars

Example 2

Check a deadline

Noah has 18 dollars and saves 6 dollars a week. Will he have enough for a 50-dollar helmet after 5 weeks?

New savings: $5 \times 6 = 30$ dollars.
Total: $18 + 30 = 48$ dollars.
$50 - 48 = 2$ dollars, so he is still short.
After 6 weeks he would have $18 + 36 = 54$ dollars if the plan stays the same.

No. He will have 48 dollars, 2 dollars short.

Check your understanding

Receive 10 dollars each week and spend 3 dollars each week. How much can you save in 4 weeks?

Show answer

28 dollars

Keep $10 - 3 = 7$ dollars each week. Then $4 \times 7 = 28$ dollars.
