The $100 Teen Party Challenge: A Budgeting Game with Six Surprise Rounds
30-minute lesson · teams of 3–4 · fictional event budget and cost cards
By the Right Price team
Give each team a fictional $100 budget to plan a ten-person class event. They must cover required supplies, choose optional extras, and adjust when the situation changes. The activity separates two tasks: estimating a cost and deciding what to keep when the budget is limited. No student needs to disclose their family's finances.
Playable kit and host resources
Price basis: supplied dollar amounts are fictional practice prices in USD, before tax and shipping. No current retailer quote is claimed. Bible cards use the named count units instead.
Rotate the $100 challenge for teens
The existing event menu and six numeric rounds remain below. Each surprise resets to the shared $85 plan unless stated otherwise. Keep the estimation/reveal score separate from each team’s planning choices. No personal household spending is needed.
| Scenario | Fictional required costs | Optional choice and checked result |
|---|---|---|
| Party for 10 | Snacks $30+drinks $10+room $15=$55 | Decor $12+game $18: total $85, reserve $15 |
| Club meeting for 10 | Materials $40+printing $10=$50 | Poster kit $15+snacks $20: total $85, reserve $15 |
| Local trip for 10 | Tickets $50+group transport $20=$70 | Map pack $5+snacks $10: total $85, reserve $15 |
Decision ledger
Use the separate editable planning ledger. For every scenario, write quantity, unit cost, line total and balance; retain at least $10. Apply one surprise to your own plan, then justify a cut. For the club, adding $8 printing to $85 leaves $7; cutting the $15 poster kit restores a $22 reserve. For the trip, a $20 transport increase makes $105; removing $15 extras reduces it to $90 and restores $10.
For ordinary paper rounds, announce closest overall, one point per item and two for a bundle before starting; share equal-distance points and allow joint overall winners. Where this guide gives a different scoring exercise, follow that section instead. These are external house rules. Right Price pricing questions default to closest without going over; keep optional paper scores separate from the app leaderboard.
How to run the 30-minute activity
- Minutes 0–5: explain required versus optional costs and model the $55 essentials calculation.
- Minutes 5–12: teams create their own first plan with a reserve of at least $10. One student checks quantities and another checks the remaining balance.
- Minutes 12–24: play the six numeric rounds below, two minutes each. Unless a prompt says otherwise, each round starts from the shared $85 example plan; surprise cards do not accumulate.
- Minutes 24–30: teams apply one chosen surprise to their own plans and justify a revision. Keep that decision exercise on paper so teams may choose different valid solutions.
Six budgeting rounds with worked answers
1. Starting balance
The shared plan includes essentials, decorations, and the game kit. What remains from $100?
Host answer and explanation
$15
$100 − ($55 + $12 + $18) = $15. The plan meets the initial $10-reserve rule.
2. More guests
Start again with the $85 plan. Two extra guests attend, each needing a $3 snack and $1 drink. What remains?
Host answer and explanation
$7
Two × ($3 + $1) adds $8. Total spend becomes $93, leaving $7. It is within $100 but below the $10 reserve, so a revision is needed if that rule still applies.
3. Price increase
Reset to the ten-person $85 plan. Snack portions increase from $3 to $3.50 each. What is the new total spending?
Host answer and explanation
$90
Ten portions each rise by $0.50, adding $5. $85 + $5 = $90, leaving exactly $10.
4. A smaller budget
Reset to the original $85 plan. The budget is reduced to $80 and the team must still keep $10. What is the minimum spending reduction needed?
Host answer and explanation
$15
The new spending ceiling is $80 − $10 = $70. Reduce $85 by at least $15. Dropping the $18 game kit works; dropping only $12 decorations does not.
5. Compare two revised plans
Plan A keeps the $55 essentials and $18 game kit. Plan B keeps the essentials, $12 decorations, and ten $1 take-home cards. How much more does Plan B cost?
Host answer and explanation
$4
Plan A costs $73. Plan B costs $77. The difference is $4. Both fit the original $100 budget with a $10 reserve; the group must decide which serves its event better.
6. Spendable money is not the whole balance
Using Plan A at $73, how much of the $100 budget remains available for extra spending if $10 must stay unspent?
Host answer and explanation
$17
$100 − $73 − $10 = $17. The balance is $27, but only $17 can be spent while preserving the reserve.
Use decisions to check learning
Ask each team to submit its original ledger and one revised ledger. Check four things: required costs are included, quantities match attendees, arithmetic reconciles to the starting budget, and the written explanation names a tradeoff. Give credit for different choices when they satisfy the constraints.
For a shorter lesson, use the menu and rounds 1–3. For a harder lesson, let teams propose a new optional item with an assigned price, then have another team audit the ledger. Keep new costs clearly fictional unless you supply actual dated quotes.
Debrief prompts: Which cost changed with attendance? Which cost was paid once? What did the reserve protect? What information would you need before planning a real event? The goal is explaining a plan, not judging students by personal spending preferences.
Use Right Price for the reveal rounds
- Enter the six fixed numeric questions in a manual price/number game and use them for the whole-class estimate-and-reveal portion.
- Keep each team's event plan and budget ledger on paper or in your own document. This activity does not require or claim an automatic budget simulation in Right Price.
- You can preview the Financial Literacy Estimates starter, then replace its sample rounds manually. Use discussion and the revised ledger alongside the game score.
The public guide can be read without an account. Creating or hosting a game uses the product's sign-in and access flow; check current plans before your event. Answer disclosures on this page are convenient to hide, not private or access-controlled.
