Value of a Penny

• Pennies have a value of .01 each
• This value is said as one cent
• A penny is 1/100th of 1 dollar
• So it takes 100 pennies to equal 1.00
• Former President Abraham Lincoln appears on the
  front of all pennies.

7
Value of a Nickel

• Nickels have a value of .05 each
• This value is said as five cents
• A nickel is worth 5/100ths of 1 dollar
• So it takes 20 nickels to equal 1.00
• Former President Thomas Jefferson appears on the
  front of all nickels.

8
Value of a Dime

• Dimes are worth .10 each
• This value is said as ten cents
• A dime is worth 10/100ths of 1 dollar
• So it takes 10 dimes to equal 1.00
• Former President Franklin D. Roosevelt appears
  on the front of all dimes.

9
Value of a Quarter

• A quarter is worth .25
• This value is said as twenty-five cents
• A quarter is worth 1/4th of 1 dollar
• So it takes 4 quarters to equal 1.00
• Former President George Washington appears on
  the front of all quarters.

10
Addition of Coins

• One method of adding coins is to think of all
  coins in terms of cents and then add like normal
• For example 10 cents 5 cents 15cents
• So a dime plus a nickel equals 15 cents, which is
  still less than a quarter at 25 cents

11
Addition of Coins

• Another method of adding coins is to set up the
  question like a Math problem
• For example .25
• .01
• .26
• This method works well when adding numbers that
  are too high to count

12
Subtraction of Coins

• One method of subtracting coins is to think of
  all coins in terms of cents and then subtract
  like normal
• For example 10 cents 1 cent 9 cents
• So a dime minus a penny is worth more than a
  nickel, but less than the dime you started with

13
Subtraction of Coins

• Another method of subtracting coins is to set up
  the question like a Math problem
• For example .25
• - .10
• .15
• This method works well when subtracting numbers
  that are too high to count
