What they’re learning
Your child is learning to make simple financial decisions: total costs, compare choices, work within a budget, and explain trade-offs.
Explain it to my child
A budget is a plan for money. If you have $20, choosing one item may mean you cannot choose another. Math helps you see the trade-off before buying.
Try it together
Give a pretend budget of $25 and make a menu of household “items” with prices. Ask your child to choose 2–4 items without going over budget and calculate what remains.
Practice
- You have $30 and spend $18.75. What remains?
- Two items cost $6.40 and $8.35. Total?
- Which is cheaper: three $2 items or one $7 item?
- You save $4 each week. How much after 6 weeks?
- A $20 budget includes $12.50 and $5.25 purchases. Is there enough for a $3 item?
Check understanding
- Can your child stay within a budget and show their calculation?
- Can they explain a trade-off rather than only finding a total?
Parent answer guide
