Sarah has 7 pennies
Each penny = 1¢, so 7 pennies = 7 × 1¢ = 7¢
Sarah has 7¢
Sarah has 7 cents (7¢)
• Counting rule: Number of pennies × 1¢ = Total value
• Unit notation: Use ¢ for cents
• Simple multiplication: Any number × 1 = itself
Nickel: Worth 5 cents (5¢). Each nickel equals 5¢.
Tom has 3 nickels
Each nickel = 5¢, so 3 nickels = 3 × 5¢ = 15¢
Tom has 15¢
Tom has 15 cents (15¢)
• Counting rule: Number of nickels × 5¢ = Total value
• Unit notation: Use ¢ for cents
• Multiplication: 3 × 5 = 15
Dime: Worth 10 cents (10¢). Each dime equals 10¢.
Emma has 4 dimes
Each dime = 10¢, so 4 dimes = 4 × 10¢ = 40¢
Emma has 40¢
Emma has 40 cents (40¢)
• Counting rule: Number of dimes × 10¢ = Total value
• Unit notation: Use ¢ for cents

Mixed coins: Count each type separately, then add totals.
2 quarters = 2 × 25¢ = 50¢
3 dimes = 3 × 10¢ = 30¢
5 pennies = 5 × 1¢ = 5¢
50¢ + 30¢ + 5¢ = 85¢
Jake has 85 cents (85¢)

1 quarter = 1 × 25¢ = 25¢
40¢ > 25¢, so Alex has more money
Alex has more money than Sam
Alex has more money (40¢ vs 25¢)
• Calculate rule: Find total value for each person
• Compare rule: Use >, <, or = to compare amounts
• More is better: Higher value means more money
