3 x 4 = 12 factor factor product

3
* ANYTHING multiplied by zero is ZERO. 2 x 0 = Two groups of zero. NOTHING in the groups means that the product is zero.

4
10 x 0 =0 x 3 = 0 x 4 =5 x 0 = 7 x 0 =0 x 6 = 0 x 2 =8 x 0 =

5
* ANYTHING multiplied by one is the same number. 4 x 1 = Four groups of one = 4 Add the amount in each group together and you have 4. It’s like looking in a mirror!!!

6
10 x 1 =1 x 3 = 1 x 4 =5 x 1 = 7 x 1 =1 x 6 = 1 x 2 =8 x 1 =

7
* The order of the FACTORS does not affect the product!!!! 3 x 4 = 4 x 3

8
2 x 3 = 3 x ? 4 x 5 = ? x 4 3 x ? = 8 x 3

9
* If you have THREE factors, the order does not matter. (5 x 3) x 2 = 5 x (3 x 2)

10
5 x 2 x 1 = 10, so try 2 x 1 x 5 = 4 x 3 x 2 = 24, so try 3 x 2 x 4 = 2 x 2 x 10 = 40, so try 10 x 2 x 2=

11
* Don’t get nervous. This is NOT a hard one! It’s just NEW!! This property makes it easy to multiply smaller facts that you may know. * Look at the array. What do you notice? * 4 x 7 = ( 4 x 4 ) + ( 4 x 3 )

12
Draw an array with four rows of six. Now let’s color two of the columns red. Color the remaining columns blue. ( 4 x ___ ) + (4 x ___ )

13
5 x 6 = (5 x 3) + ( 5 x __ ) 4 x 5 = (4 x 2) + (4 x __ ) 3 x 2 = (3 x 1) + (3 x __ )
