Counting: Adding up the total value of coins
Penny: Worth 1 cent (1¢), copper-colored
Nickel: Worth 5 cents (5¢), silver-colored
Dime: Worth 10 cents (10¢), silver-colored
Quarter: Worth 25 cents (25¢), silver-colored
Dollar Coin: Worth 100 cents (100¢), golden-colored
Total: The sum of all coin values
Grouping: Organizing same coins together to make counting easier
Value: How much money each coin is worth
Comparison: Seeing which group of coins has more value
- Group same coins: Count all pennies together, all nickels together, etc.
- Multiply within groups: Use multiplication to count same coins faster
- Add group totals: Add all group totals to get the final amount
- Start with largest: Count dollar coins first, then quarters, dimes, nickels, pennies
- Check your work: Count again if possible to verify accuracy
- Convert units: Know that 100¢ = $1

Counting pennies: Adding up the value of multiple 1¢ coins
- Count the number of pennies
- Multiply by the value of each penny (1¢)
- State the total value
There are 8 pennies
8 × 1¢ = 8¢
Total = 8¢
8¢
• Counting: Count the number of coins
• Multiplication: Number of coins × value per coin
• Unit: Answer in cents (¢)
🪙🪙 (pennies) + 🪙🪙 (nickels) + 🪙 (dime) + 🪙 (quarter)
Counting mixed coins: Adding up the total value of different types of coins
2 pennies = 2 × 1¢ = 2¢
2 nickels = 2 × 5¢ = 10¢
1 dime = 1 × 10¢ = 10¢
1 quarter = 1 × 25¢ = 25¢
2¢ + 10¢ + 10¢ + 25¢ = 47¢
47¢
• Grouping: Group same coins together
• Multiplication: Number of coins × value per coin
• Addition: Add all group totals together
🪙🪙🪙 (pennies) + 🪙🪙 (nickels) + 🪙🪙 (dimes) + 🪙 (quarter) + 🪙 (dollar)
Advanced counting: Adding up the total value of multiple different types of coins including dollar coins
3 pennies = 3 × 1¢ = 3¢
2 nickels = 2 × 5¢ = 10¢
2 dimes = 2 × 10¢ = 20¢
1 quarter = 1 × 25¢ = 25¢
1 dollar coin = 1 × 100¢ = 100¢
3¢ + 10¢ + 20¢ + 25¢ + 100¢ = 158¢
158¢ (or $1.58)
• Grouping: Group same coins together
• Multiplication: Number of coins × value per coin
• Addition: Add all group totals together
• Unit conversion: 100¢ = $1
Group A: 🪙 (quarter) + 🪙 (dime) + 🪙 (nickel)
Group B: 🪙🪙🪙 (quarters)
Comparison: Determining which group of coins has greater value
1 quarter + 1 dime + 1 nickel = 25¢ + 10¢ + 5¢ = 40¢
3 quarters = 3 × 25¢ = 75¢
40¢ < 75¢
Group B has more value
Group B (3 quarters = 75¢) has more value than Group A (40¢)
• Grouping: Group same coins together
• Multiplication: Number of coins × value per coin
• Addition: Add all values in each group
• Comparison: Use >, <, or = symbols
She wants to buy a book that costs $1.45. Does she have enough money?
Shopping problem: Using coins to determine if you can afford something
2 pennies = 2¢, 1 nickel = 5¢, 1 dime = 10¢, 1 quarter = 25¢, 1 dollar = 100¢
2¢ + 5¢ + 10¢ + 25¢ + 100¢ = 142¢
142¢ = $1.42
$1.42 < $1.45
No, Emma does not have enough money
No, Emma does not have enough money. She has $1.42 but needs $1.45.
• Counting: Add up all coin values
• Unit conversion: 100¢ = $1
• Comparison: Money ≥ Cost means enough money
• Real-world application: Use math for shopping decisions
Grouping: Organize same coins together before counting
Multiplication: Use multiplication instead of repeated addition
Order: Count coins from largest to smallest value
Verification: Double-check your work by recounting
Visualization: Draw lines under same coins to group them
Patterns: Recognize skip counting patterns (5s, 10s, 25s)
Unit conversion: Know that 100¢ = $1
Comparison: Compare values of different coin groups
- Scan: Quickly identify all coin types present
- Sort: Mentally or physically group same coins together
- Count: Use skip counting for each group (100s for dollars, 25s for quarters, 10s for dimes, etc.)
- Record: Write down each group's total
- Add: Sum all group totals to get the final amount
- Convert: Change cents to dollars when needed (100¢ = $1)
- Verify: Count again if time allows
• Always write the cents symbol (¢) or dollar sign ($) after your answer
• Keep coins organized to avoid miscounting
• Use scratch paper to record intermediate totals
• Practice with increasingly complex coin combinations
• Time yourself to build speed while maintaining accuracy
• Know that 100 cents equals 1 dollar
