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
Total: The sum of all coin values
Grouping: Organizing same coins together to make counting easier
Value: How much money each coin is worth
Assessment: Testing your knowledge and skills
- 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 quarters first, then dimes, nickels, pennies
- Check your work: Count again if possible to verify accuracy
- Include units: Always add the cents symbol (¢) to answers

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 4 pennies
4 × 1¢ = 4¢
Total = 4¢
4¢
• Counting: Count the number of coins
• Multiplication: Number of coins × value per coin
• Unit: Answer in cents (¢)
🪙 (penny) + 🪙 (nickel) + 🪙 (dime) + 🪙 (quarter)
Counting mixed coins: Adding up the total value of different types of coins
1 penny = 1 × 1¢ = 1¢
1 nickel = 1 × 5¢ = 5¢
1 dime = 1 × 10¢ = 10¢
1 quarter = 1 × 25¢ = 25¢
1¢ + 5¢ + 10¢ + 25¢ = 41¢
41¢
• Grouping: Group same coins together
• Multiplication: Number of coins × value per coin
• Addition: Add all group totals together

Counting multiple same coins: Adding up the value of several identical coins
There are 5 nickels
5 × 5¢ = 25¢
Total = 25¢
25¢
• Counting: Count the number of coins
• Multiplication: Number of coins × value per coin
• Unit: Answer in cents (¢)
🪙🪙 (pennies) + 🪙 (nickel) + 🪙🪙 (dimes) + 🪙 (quarter)
Complex counting: Adding up the total value of multiple different types of coins
2 pennies = 2 × 1¢ = 2¢
1 nickel = 1 × 5¢ = 5¢
2 dimes = 2 × 10¢ = 20¢
1 quarter = 1 × 25¢ = 25¢
2¢ + 5¢ + 20¢ + 25¢ = 52¢
52¢
• Grouping: Group same coins together
• Multiplication: Number of coins × value per coin
• Addition: Add all group totals together
Shopping assessment: Using coins to determine if you can afford something
3 quarters = 3 × 25¢ = 75¢
2 dimes = 2 × 10¢ = 20¢
4 pennies = 4 × 1¢ = 4¢
Total = 75¢ + 20¢ + 4¢ = 99¢
Money = 99¢
Cost = 99¢
99¢ = 99¢
Yes, he has exactly enough money
Yes, Sam has exactly 99¢, which is enough to buy the toy
• Addition: Add all coins to find total
• Comparison: Money ≥ Cost means enough money
• Real-world application: Use math for shopping decisions
Identification: Recognizing coins by their appearance and value
Counting: Adding up the total value of multiple coins
Grouping: Organizing same coins together for efficient counting
Comparison: Using coin values to make shopping decisions
Accuracy: Getting the correct total every time
Speed: Counting efficiently and quickly
- Read carefully: Understand what each question is asking
- Group coins: Count same coins together first
- Use multiplication: Multiply same coins instead of adding repeatedly
- Add systematically: Add group totals in order
- Check your work: Count again if time permits
- Include units: Always add the cents symbol (¢) to answers
