2 FACT FAMILY | DOUBLING
A quick tip to remembering the 2 fact family is to double the other number.

The 2 fact family is as easy as addition – simply double the number that is being multiplied by two.

2 FACT FAMILY | SKIP COUNTING
Use skip counting to arrive at the answer

Skip-counting is counting while skipping one or more numbers in a pattern.  To skip count by 2, skip one number while counting.

To skip-count by two, read all of the numbers highlighted in orange below (2, 4, 6, 8, 10, 12, 14, and so on).  Skip-counting is also called “counting by 2s.”

 

To use skip-counting to arrive at a multiplication answer, skip count to the number you are multiplying by 2.

4 FACT FAMILY | DOUBLE-DOUBLE
To remember the 4 fact family, double the number that is being multiplied by 4 twice. 

For example, to multiply 4 x 6, 6 doubled once is 12, and 12 doubled once is 24.  The answer to 4 x 6 is 24.

Rather than addition, an alternate way to think about double-double is to multiply by 2. 

For example, to multiply 4 x 6, 6 x 2 is 12, and 12 x 2 is 24.  The answer to 4 x 6 is 24. 

5 FACT FAMILY | SKIP COUNTING
Use skip-counting to arrive at the answer.

Skip-counting is counting while skipping one or more numbers in a pattern.  To skip count by 5, count every fifth number.

To skip-count by five, read all of the numbers highlighted in orange below (5, 10, 15, 20, and so on).  Skip-counting is also called “counting by 5s.”

1     2     3     4     5     6     7     8     9     10     11     12     13     14     15       . . .

To use skip-counting to arrive at a multiplication answer, skip count to the number you are multiplying by 5.
