# Multiplication - Multiplication Strategies

• Multiplication Strategies

BASICS:  two numbers being multiplied together are called factors and the answer to a multiplication problem is called the product...ie  In 4x5=20, 4 and 5 are factors and 20 is the product

* 0's facts - The Zero Property of Multiplication says that any factor times 0 is ALWAYS 0 ...ie 3x0=0

* 1's facts - The Identity Property of Multiplication says that any factor times 1 is always the other factor...ie 1x7=7

* 2's facts - Skip count or simply count by 2's the number of times that the other factor says...ie 2x4=8 because I counted by 2's 4 times 2,4,6,8

* 5's facts - Count by 5's the number of times that the other factor says...ie 4x5=20 because I counted by 5's 4 times 5,10,15,20

* 9's facts - Use your hands...hold both hands out in front of you and using the factor of than 9, count over the number of finger and put that finger down.  The number of fingers that are to the left of the finger you just put down is the first digit in the product.  The number of fingers to the right of the finger you just put down is the second digit in the product.
