The Nine's Trick

In order subtraction trick
When subtracting, if the numbers run in order the answer will always be 9

11 - 2 = 9  (1 and 2)
12 - 3 = 9  (2 and 3)
13 - 4 = 9  (3 and 4)
14 - 5 = 9  (4 and 5)
15 - 6 = 9  (5 and 6)
16 - 7 = 9  (6 and 7)
17 - 8 = 9  (7 and 8)
18 - 9 = 9  (8 and 9)

Teens Trick
When subtracting a 9 from a teen, add the 2 digits together for the answer

11 - 9 = 2  (1 + 1 = 2)
12 - 9 = 3  (1 + 2 = 3)
13 - 9 = 4  (1 + 3 = 4)
14 - 9 = 5  (1 + 4 = 5)
15 - 9 = 6  (1 + 5 = 6)
16 - 9 = 7  (1 + 6 = 7)
17 - 9 = 8  (1 + 7 = 8)
18 - 9 = 9  (1 + 8 = 9)

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.
