(At the bottom of the page is a printable of Money help notes.)

In our money unit we will be learning how to count money, how to add and subtract money, and to determine the least amount of coins.

 Review from 3rd grade:  Penny = 1 cent, Nickel = 5 cents, Dimes = 10 cents, Quarters = 25 cents, and Half Dollars = 50 cents.

 When we count money, skip-counting is an easy way to find out how much money we have.  When skip-counting coins, we count by 5's for nickels, 10's for dimes, 25's for quarters, and 50's for half dollars.  When different coins are mixed together you count the coins with the largest value first.  For example:  the coins below would be counted as 10, 20, 30, 35, 40.  The set of coins equals 40 cents.

 We also use skip-counting to make change or check to see if your change is correct.  Skip-count up from the amount owed to the amount of money paid to find the change needed.

 There are many different combinations of coins that can make up an amount of change, but we often want to get the fewest number of coins.  If you went to the store and received a $1.00 in change would you rather have 100 pennies or a one dollar bill?  In the example below the quarter is the fewest amount of coins that make 25 cents.  It only takes 1 coin to make 25 cents with the quarter.  It takes 3 coins to make 25 cents with the two dimes and one nickel. 

 When you add and subtract money amounts remember to line up the decimals just like you did in the Decimal unit.
