Math Fact Strategie

As your child is learning basic math facts, it may help him or her to understand a few simple strategies to help solve these facts.  Yes, ultimately we want children to just know them, but in the meantime they need a strategy.

Counting On -
This strategy is used when adding 1,2, or 3 to any number.
For example:
7+2= __.  Tell your child to put the bigger number in their mind and count up 2. (think 7,8,9)  Other examples would be 3 + 6 =__ (think 6,7,8,9) or     8 + 1 =__ (think 8, 9)
Next, a child must know all of the ten facts and all of the double facts.  Once your child has mastered these, you can move on to the other strategies.

Ten Facts
5 + 5                         6 + 4                        3 + 7
4 + 6                         7 + 3                        9 + 1
1 + 9                         8 + 2                        2 + 8

Double Facts
1 + 1                                 2 + 2                             3 + 3
4 + 4                                5 + 5                             6 + 6
7 + 7                                8 + 8                             9 + 9

Doubles Plus One
If your child is learning a fact like 6 + 7, these are the steps to think through:
* Double the lower number, which in this case would give you 6 + 6 =12.
* Now add one:(The second 6 was a 7, remember?)
* Think 6 + 6 + 1 = 13 or 12 + 1 = 13.
* Now say the fact: 6 + 7 = 13

One of the things that we must help children do is recognize when to use a particular strategy.  For the Doubles Plus One strategy tell the children "when the numbers are next door neighbors (the numbers are consecutive like 6 and 7) then we can use the doubles plus one strategy."

Doubles Plus Two
If a child is faced with the 5 + 7 , think through the same steps as Doubles Plus One except add 2 instead of one.  This works for facts that have number that are separated by two.  When helping a child to recognize when to use this strategy tell them to use it "when the numbers are NOT next door neighbors, but two doors down from each other."

Plus 9 Shortcut
If your child is learning a fact like 9 + 5 these are the steps to think through:
* Think 10 + 5 = (which is much easier to add)
* Now minus 1 (Think 15 - 1 + 14)
* Now say the fact: 9 + 5 = 14
* Remind your child that you added 10 + 5 instead of 9 + 5.  That's one more than you started with, so you have to take that one away to get to the correct answer.
