How much do you have in all?

Pile #1 = 1 nickel and 4 pennies.

How much do you have in all?

Do you remember ...

1 dime = 2 nickels
1 dime = 10 pennies
1 nickel = 5 pennies

Did you remember that the plural of penny is either pennies or pence?

Did you know you have verified ...

10 + 9 = 19
and that you have picked up nouns!

A noun is the name of a person, place, thing, or idea. It is hard to pick up an idea or place, but the other things you can frequently pick up !!!

Be sure to review these math families frequently. Have your child illustrate these families using any number of items found in the house ...

coins, m&ms, toys, shoes, buttons, etc.

Make flashcards out of index cards for your child for the math families. Flash your child daily going quickly, cheerfully, and happily.

You may want to keep track with your child those facts he already knows with the Addition Chart and the Subtraction Chart.
