Learn fundamental principles of financial decisions including earning, spending, saving, and budgeting through detailed exercises with step-by-step solutions.

Financial Decision Principles: Earning and Spending
1 Earning Money
Exercise 1
Emma earns $2 for each chore she completes. If she does 5 chores, how much money does she earn? Should she spend it all?
Definition:

Earning: Getting money by doing work or providing a service

Earning Method:
  1. Identify the rate of pay per unit
  2. Count the number of units completed
  3. Multiply the rate by the number of units
  4. Decide how to use the money wisely
Rate
$2 per chore
Chores Done
5 chores
Total Earned
$10
Step 1: Calculate total earnings

$2 per chore × 5 chores = $10 earned

Step 2: Consider financial principles

Follow the 50-30-20 rule: 50% needs, 30% wants, 20% savings

Step 3: Apply principle to decision

$5 for needs, $3 for wants, $2 for savings

Step 4: Make the decision

No, don't spend it all - save some for future needs

Emma earns $10, should save $2
Best decision:

Emma should save $2 and spend $8 wisely

Applied principles:

• Save First: Set aside some money before spending

• Budgeting: Plan how to use money wisely

• Balance: Meet needs while enjoying wants

2 Making Smart Spending Decisions
Exercise 2
Tom has $15. He wants a book ($8) and a snack ($4). How should he decide what to buy?
Definition:

Spending Decision: Choosing how to use money based on priorities and budget

Available Money
$15
Total Wants
$12
Left Over
$3
Step 1: List all desired purchases

Book: $8, Snack: $4

Step 2: Calculate total cost

$8 + $4 = $12

Step 3: Compare with available money

$12 < $15, so both can be bought

Step 4: Consider priorities

Is the book more important than the snack?

Step 5: Make the decision

Buy both since they fit in the budget

Available Money:
$15
Book:
$8
Snack:
$4
Total Spent:
$12
Left Over:
$3
Buy both, save $3
Best decision:

Tom should buy both the book and snack, saving $3

Applied principles:

• Budget Check: Ensure spending fits within available money

• Prioritization: Decide what's most important

• Value: Get maximum benefit from money spent

3 Saving Money
Exercise 3
Maya has $20. She wants to buy a game ($15) but also wants to save for a bigger toy ($30). What should she do?
Definition:

Saving: Setting aside money for future purchases or needs

Available Money
$20
Immediate Want
Game = $15
Future Goal
Toy = $30
Step 1: Identify immediate vs future goals

Immediate: Game ($15), Future: Toy ($30)

Step 2: Assess urgency of each goal

Is the game urgent? Can the toy wait?

Step 3: Consider opportunity cost

If Maya buys the game, she has $5 left. She'd need $25 more for the toy.

Step 4: Make a compromise decision

Buy the game now ($15) and start saving the remaining $5

Step 5: Plan for future saving

Continue saving to reach the $30 goal for the toy

Available Money:
$20
Game Purchase:
$15
Money Left:
$5
Toy Goal:
$30
Buy game, save $5, continue saving for toy
Best decision:

Maya should buy the game now and start saving for the bigger toy

Applied principles:

• Balance: Enjoy today while planning for tomorrow

• Goals: Set both short-term and long-term objectives

• Flexibility: Adapt plans as circumstances change

Questions & Answers

Question: How can I teach my child to apply financial decision principles in real life?

Answer: Here are practical ways to teach financial decision principles:

  • Give real money: Let them handle actual coins and bills
  • Set up savings goals: Help them save for something they want
  • Involve them in shopping: Let them compare prices and make choices
  • Give regular income: Allowance or chore payments to practice earning
  • Discuss decisions: Talk about why certain choices are better

For example: "You have $10. Would you rather buy the $8 toy now or save $2 and wait for a $20 toy later?"

This gives them hands-on experience with the principles we've discussed.

Question: What classroom activities can reinforce financial decision principles?

Answer: Effective classroom activities include:

  • Mock store: Set up a store with real prices and let students shop with play money
  • Budget challenges: Give students money and ask them to make optimal choices
  • Decision trees: Create flowcharts showing different choices and outcomes
  • Group projects: Have teams plan purchases together
  • Goal setting: Help students set and plan for financial goals

These activities make abstract concepts concrete and allow students to practice decision-making in a safe environment.

Encourage students to explain their reasoning behind their financial choices.

Question: What should I do if I want something expensive but can't afford it?

Answer: Great question! Here are smart approaches:

  • Save up: Put money aside each week until you have enough
  • Find alternatives: Look for cheaper versions or wait for sales
  • Set priorities: Decide if it's more important than other things
  • Wait and think: You might not want it later

For example: If you want a $30 toy but only have $10, you could save $2 per week for 10 more weeks.

Learning to delay gratification builds strong financial habits for life!
