Counting Coins — Answer Key
Part A: Multiple Choice
Circle the letter of the best answer.
1. Sam has 1 quarter and 1 dime. How many cents does Sam have?
A) 30 cents
B) 35 cents
C) 26 cents
D) 40 cents
A quarter = 25 cents and a dime = 10 cents, so 25 + 10 = 35 cents.
2. Which group of coins is worth the most?
A) 3 dimes
B) 1 quarter + 1 penny
C) 2 dimes + 1 nickel
D) 5 nickels
3 dimes = 30 cents, 1 quarter + 1 penny = 26 cents, 2 dimes + 1 nickel = 25 cents, and 5 nickels = 25 cents. 30 cents is the most.
3. Mia wants to buy a sticker that costs 30 cents. She has 1 quarter. How many more pennies does she need?
A) 3 pennies
B) 5 pennies
C) 10 pennies
D) 15 pennies
A quarter = 25 cents. Mia needs 30 - 25 = 5 more cents, which equals 5 pennies.
4. Jake has 2 dimes and 3 pennies. Lily has 1 quarter. Who has more money?
A) Jake
B) Lily
C) They have the same
D) Not enough information
Jake has 2 dimes + 3 pennies = 20 + 3 = 23 cents. Lily has 1 quarter = 25 cents. Since 25 > 23, Lily has more money.
Part B: Fill in the Missing Amount
Write the missing number on each line.
1. 1 dime + 4 pennies = 14 cents.
A dime = 10 cents. To reach 14 cents, you need 14 - 10 = 4 more pennies.
2. 1 quarter + 1 nickel = 3 dimes.
1 quarter + 1 nickel = 25 + 5 = 30 cents. Since each dime = 10 cents, 30 / 10 = 3 dimes.
3. 5 nickels have the same value as 1 quarter.
A quarter = 25 cents. Each nickel = 5 cents, so 25 / 5 = 5 nickels.
4. 1 quarter - 1 dime = 15 cents.
A quarter = 25 cents and a dime = 10 cents. The difference is 25 - 10 = 15 cents.
5. 2 dimes + 1 nickel + 5 pennies = 30 cents.
2 dimes + 1 nickel = 20 + 5 = 25 cents. To reach 30 cents, you need 30 - 25 = 5 more pennies.
