Breaking apart larger multiplication facts into two smaller facts.
When we solve our:
6 facts: Use our 5 and 1 facts
7 facts: Use 5 and 2 facts
8 facts: Use 5 and 3 facts
When you multiply more than 2 digits, you can group them in any order and
you will get the same answer.
6x5 x2
(6x5)x2= 30x2=60
6x(5x2)=6 x 10=60
So.... 6x(5x2)=(6x5)x2
The order of the numbers does not matter.
Once you learn 3x5= 15,
you know that 5x3= 15.
Rules:
Any number multiplied by 2 is an even number
Double the other factor
Multiplication is equal groups with the same amount in each group.
Division is breaking up a large number into equal groups.
