Coin: A flat, round piece of metal used as money
Value: The amount of money a coin is worth, measured in cents (¢)
Cents: The basic unit of money, where 100 cents equal 1 dollar ($1)
Counting: Adding up the total value of coins to find how much money you have
Comparison: Determining which set of coins is worth more or less
Equivalence: Different combinations of coins that have the same total value
- Memorize values: Know each coin's value by heart
- Group like coins: Count same coins together first
- Count largest first: Start with quarters, then dimes, nickels, pennies
- Add systematically: Keep track of running total
- Check your work: Count again if possible
🪙 1¢ 🪙 5¢ 🪙 10¢ 🪙 25¢
Identification: Recognizing coins by their value
- Recall the value of each coin
- Find the coin that matches the target value
- Circle or select the correct answer
Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢
We need the coin worth 5 cents
5¢ corresponds to the Nickel
The nickel (5¢) is the correct coin
• Memorization: Remember each coin's value
• Matching: Match value to coin name
• Selection: Choose the correct option
🪙🪙🪙🪙 (pennies) + 🪙🪙 (nickels) + 🪙 (dime)
Counting: Adding up the value of multiple coins
4 pennies = 4 × 1¢ = 4¢
2 nickels = 2 × 5¢ = 10¢
1 dime = 1 × 10¢ = 10¢
4¢ + 10¢ + 10¢ = 24¢
The total is 24¢
• Multiplication: Number of coins × value per coin
• Addition: Add all coin values together
• Unit: Answer in cents (¢)
Fill in: 3 dimes ___ 2 quarters
Comparison: Determining which group has greater value
3 × 10¢ = 30¢
2 × 25¢ = 50¢
30¢ < 50¢
3 dimes < 2 quarters (30¢ < 50¢)
• Multiplication: Count total value of each group
• Comparison: Use >, <, or = symbols
• Logic: Higher number means more value
_____ nickels = 1 quarter
Equivalence: Finding how many coins of one type equal another
1 quarter = 25¢
1 nickel = 5¢
? nickels × 5¢ = 25¢
? = 25¢ ÷ 5¢ = 5
5 nickels equal the value of 1 quarter
• Division: Total value ÷ value per coin = number of coins
• Equivalence: Same value in different forms
• Algebra: Setting up and solving equations
Shopping Problem: Using money to determine if you can afford something
2 quarters = 2 × 25¢ = 50¢
1 dime = 1 × 10¢ = 10¢
4 pennies = 4 × 1¢ = 4¢
Total = 50¢ + 10¢ + 4¢ = 64¢
Money = 64¢
Cost = 64¢
64¢ = 64¢
Yes, she has exactly enough money
Yes, Emma has exactly 64¢, which is enough to buy the pencil
• Addition: Add all coins to find total
• Comparison: Money ≥ Cost means enough money
• Real-world Application: Use math for shopping decisions
Preparation: Before starting, review all coin values and their appearances
Organization: Sort coins by type before counting
Systematic approach: Work through problems in order
Verification: Check answers when possible
- Read carefully: Understand what each question is asking
- Identify coins: Look at each coin's value
- Plan your approach: Decide on the best method to solve
- Calculate systematically: Show your work clearly
- Check your answer: Make sure it makes sense
• Always write the cents symbol (¢) after your answer
• Show your work to get partial credit
• Use neat handwriting so others can read your answers
• Don't erase completely - cross out mistakes and try again
• Ask for help if you're stuck, but try first
