2 quarters, 3 dimes, 1 nickel, 4 pennies
Money Values: Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢
- Identify each coin and its value
- Count how many of each coin you have
- Multiply the number of each coin by its value
- Add all amounts together
2 quarters = 2 × 25¢ = 50¢
3 dimes = 3 × 10¢ = 30¢
1 nickel = 1 × 5¢ = 5¢
4 pennies = 4 × 1¢ = 4¢
50¢ + 30¢ + 5¢ + 4¢ = 89¢
2 quarters, 3 dimes, 1 nickel, 4 pennies = 89¢
• Value recognition: Know the value of each coin
• Multiplication: Number of coins × value of each coin
• Addition: Add all calculated amounts together
3 quarters vs 2 quarters + 5 dimes
Comparison: Compare two amounts using >, <, or =
3 × 25¢ = 75¢
50¢ + 50¢ = 100¢
3 quarters = 3 × 25¢ = 75¢
2 quarters = 2 × 25¢ = 50¢
5 dimes = 5 × 10¢ = 50¢
Total = 50¢ + 50¢ = 100¢
75¢ < 100¢
3 quarters < 2 quarters + 5 dimes
2 quarters + 5 dimes is greater than 3 quarters
• Calculate separately: Find the value of each group
• Compare values: Use comparison symbols >, <, or =
• Order matters: Be careful with which amount is larger
Making change: Money returned when payment is more than cost
3 quarters = 3 × 25¢ = 75¢
Change = Payment - Cost
Change = 75¢ - 47¢ = 28¢
28¢ = 1 quarter (25¢) + 3 pennies (3¢)
Cost + Change = 47¢ + 28¢ = 75¢ = Payment ✓
You get 28¢ in change (1 quarter and 3 pennies)
• Subtraction: Change = Payment - Cost
• Coin combination: Express change using fewest coins possible
• Verification: Check that Cost + Change = Payment
Word problems: Real-life scenarios requiring math calculations
2 dimes = 2 × 10¢ = 20¢
3 nickels = 3 × 5¢ = 15¢
Sarah's total = 20¢ + 15¢ = 35¢
1 quarter = 1 × 25¢ = 25¢
2 pennies = 2 × 1¢ = 2¢
Tom's total = 25¢ + 2¢ = 27¢
35¢ > 27¢
Sarah has more money than Tom
Sarah has more money (35¢ > 27¢)
• Problem breakdown: Separate each person's coins
• Individual calculation: Find total for each person
• Comparison: Compare the final totals
Pattern problems: Repeated actions over time
2 dimes per day = 2 × 10¢ = 20¢ per day
Emma saves for 5 days
Total = Daily amount × Number of days
Total = 20¢ × 5 = 100¢ = $1.00
100¢ = $1.00
Emma saves $1.00 in total
• Multiplication: Daily amount × Number of days
• Conversion: 100¢ = $1.00
• Pattern recognition: Same amount saved each day
