Multiplication Strategies

We began learning our facts last week. First up, x2 and x5!

Our strategies for x2 are:
           -double the other factor
              ex: 5x2, think 5+5

            -count by 2's, the other factor tells us how many times
               ex: 5x2, think 2, 4, 6, 8, 10

*** All the multiples of 2 end in an even number.

Our strategy for x5 is:
               -count by 5's, the other factor tells us how many times
                 ex: 5x3, think 5, 10, 15  

***All the multiples of 5 end in 0 or 5.

You can begin practicing facts at home using flash cards.
