Coin equivalence: Understanding that different combinations of coins can have the same value
- Count each group of coins separately
- Convert all coins to cents
- Compare the total values
- Match equivalent amounts
Both groups equal $1.00, so they are equivalent!
4 quarters = 4 × 25¢ = 100¢ = $1.00
10 dimes = 10 × 10¢ = 100¢ = $1.00
$1.00 = $1.00, so the amounts are equal
Both groups of coins are worth the same amount!
• Coin values: Quarter = 25¢, Dime = 10¢, Nickel = 5¢, Penny = 1¢
• Equivalence: Different combinations can equal the same value
• Comparison: Use = symbol for equal amounts
