Solution: Exercises 1 to 3
1 Shopping Example
Exercise 1
Emma had $30.00. She bought a book for $15.75 and a pen for $4.25. How much money does she have left?
Example Analysis:
Component Description Details
Problem Type Subtraction Money left after spending
Given Information Starting amount $30.00
Expenses Items purchased $15.75 + $4.25 = $20.00
Question What is asked Money remaining
Example solution method:
  1. Identify total starting amount: $30.00
  2. Calculate total expenses: $15.75 + $4.25 = $20.00
  3. Subtract expenses from starting amount: $30.00 - $20.00 = $10.00
  4. Verify: $10.00 + $20.00 = $30.00 ✓
Step 1: Identify starting amount

Emma begins with $30.00.

Step 2: Calculate total expenses

$15.75 (book) + $4.25 (pen) = $20.00

Step 3: Calculate remaining money

$30.00 - $20.00 = $10.00

Step 4: Verify the answer

$10.00 + $20.00 = $30.00 ✓

Emma has $10.00 left
Final answer:

Emma has $10.00 left after her shopping. ($30.00 - $15.75 - $4.25 = $10.00)

Applied rules:

• Include dollar sign in final answer

• Show all calculations step-by-step

• Verify by adding expenses back to remainder

2 Earning Example
Exercise 2
Jake earned $12.00 for helping with chores and $8.50 for walking the neighbor's dog. Then he spent $7.25 on a snack. How much money does he have now?
Example Analysis:
Component Description Details
Problem Type Mixed operations Earning then spending
Earnings Total income $12.00 + $8.50 = $20.50
Expenses Money spent $7.25
Question What is asked Current money amount
Step 1: Calculate total earnings

$12.00 + $8.50 = $20.50

Step 2: Subtract expenses

$20.50 - $7.25 = $13.25

Step 3: Verify the calculation

$13.25 + $7.25 = $20.50 ✓

Step 4: State the final answer

Jake has $13.25 now.

Jake has $13.25 now
Final answer:

Jake has $13.25 now. ($12.00 + $8.50 - $7.25 = $13.25)

Applied rules:

• Add earnings first, then subtract expenses

• Include dollar sign in final answer

• Verify by adding expenses back to final amount

3 Gift Example
Exercise 3
Sarah received $20 for her birthday. She wants to buy 5 stickers that cost $1.50 each. How much money will she have left after buying the stickers?
Example Analysis:
Component Description Details
Problem Type Multiplication and subtraction Cost per item × quantity
Starting Amount Gift money $20.00
Cost per Item Price of one sticker $1.50
Quantity Number of stickers 5
Step 1: Calculate cost of stickers

5 × $1.50 = $7.50

Step 2: Calculate remaining money

$20.00 - $7.50 = $12.50

Step 3: Verify the calculation

$12.50 + $7.50 = $20.00 ✓

Step 4: State the final answer

Sarah will have $12.50 left.

Sarah will have $12.50 left
Final answer:

Sarah will have $12.50 left after buying the stickers. ($20.00 - (5 × $1.50) = $12.50)

Applied rules:

• Calculate total cost before subtracting

• Include dollar sign in final answer

• Verify by adding cost back to remainder

Solution: Exercises 4 to 5
4 Comparison Example
Exercise 4
Mike has $25.50 and Anna has $18.75. How much more money does Mike have than Anna?
Example Analysis:
Component Description Details
Problem Type Subtraction Finding difference
Person 1 Mike's amount $25.50
Person 2 Anna's amount $18.75
Question What is asked How much more
Mike's Amount
$25.50
Anna's Amount
$18.75
Difference
$25.50 - $18.75 = $6.75
Step 1: Identify both amounts

Mike has $25.50, Anna has $18.75.

Step 2: Identify the operation

"How much more" indicates subtraction to find the difference.

Step 3: Set up the equation

$25.50 - $18.75 = ?

Step 4: Solve the equation

$25.50 - $18.75 = $6.75

Mike has $6.75 more than Anna
Final answer:

Mike has $6.75 more than Anna. ($25.50 - $18.75 = $6.75)

Applied rules:

• "How much more" indicates subtraction

• Subtract the smaller amount from the larger

• Include dollar sign in final answer

5 Savings Example
Exercise 5
Each week, Tom saves $4.25. How much will he save in 6 weeks? If he needs $30.00 for a toy, how many weeks will he need to save?
Example Analysis:
Component Description Details
Problem Type Multiplication and division Repeated addition and time calculation
Weekly Savings Amount per week $4.25
Time Period Number of weeks 6 weeks
Target Amount Goal for toy $30.00
6 Weeks Savings
$4.25 × 6 = $25.50
Weeks for $30
$30.00 ÷ $4.25 ≈ 7.06 weeks
Step 1: Calculate savings in 6 weeks

$4.25 × 6 = $25.50

Step 2: Calculate weeks needed for $30.00

$30.00 ÷ $4.25 = 7.06... Since he can't save part of a week, he needs 8 weeks.

Step 3: Verify the calculations

$4.25 × 7 = $29.75 (not quite enough), $4.25 × 8 = $34.00 (enough)

Step 4: State both answers

Tom saves $25.50 in 6 weeks and needs 8 weeks to save $30.00.

Tom saves $25.50 in 6 weeks; needs 8 weeks for $30.00
Final answer:

Tom will save $25.50 in 6 weeks. He will need 8 weeks to save $30.00. ($4.25 × 6 = $25.50, $30.00 ÷ $4.25 ≈ 8 weeks)

Applied rules:

• Multiplication for repeated additions

• Division to find time periods

• Include dollar signs in final answers

Questions & Answers

Question: How can I help my child understand money problems through examples? They seem to get confused when problems have more than one step.

Answer: Help your child break down multi-step examples:

  • Read slowly: Go through the example one sentence at a time
  • Identify steps: Find the first thing that needs to be done
  • Solve one step at a time: Don't try to do everything at once
  • Write down numbers: Keep track of what you know
  • Check each step: Make sure each part makes sense

Example: "Sarah has $20, spends $5, then earns $3" → Step 1: $20 - $5 = $15, Step 2: $15 + $3 = $18.

Question: What are the most effective types of money problems examples for 3rd graders?

Answer: Effective money problems examples for 3rd graders include:

  1. Shopping scenarios: Buying items with given amounts
  2. Earning money: Calculating totals from chores or jobs
  3. Saving goals: Determining time needed to save
  4. Comparison problems: Finding differences between amounts
  5. Change calculation: Determining correct change
  6. Budget planning: Allocating money for different needs

Examples should use familiar contexts like allowance, birthday money, or school supplies.

Question: Why do I need to show my work when I already know the answer from the example? Isn't it enough to just copy the answer?

Answer: Sam, copying the answer doesn't help you learn! Examples teach you HOW to solve problems:

  • Understanding: You learn the steps and reasoning
  • Practice: You build skills by doing the work
  • Confidence: You become more confident with each problem
  • Independence: You can solve new problems on your own
  • Checking: You can catch your own mistakes

Example: If you only copy "$20 - $5 = $15", you won't know how to solve "$30 - $8" on your own. But if you practice the steps, you'll be able to solve any subtraction problem!
