What is the Associative Property of Multiplication?
It is okay to change the order of how you multiply 3 factors because the product will stay the same.
What is the Distributive Property (Break Apart Strategy)?
We use a related fact is by breaking apart one of the factors. The Distributive Property is also called the Break Apart Strategy.
You decompose (break apart) one factor into two smaller equations to help solve a challenging problem.

Solve 3x2x4 using the Associative Property. Don't forget to put parentheses around the 2 factors that you're multiplying first!
(3x2)x4=6x4=24
OR
3 x (2x4)= 3 x (8)= 24
4 x(3+3)= (4x3) + (4x3) =12+12=24
OR
4 x(5+1)= (4x5) + (4x1)= 20+4=24
OR
4 x (4+2)= (4x4) + (4x2)= 16+8=24

Solve 8x3x2 using the Associative Property. Don't forget to use your parentheses! ( )
(8x3)x2=24x2=48
OR
8x(3x2)= 8x6=48
Solve 7x7 using the Distributive Property.
7 x (3+4)= (7x3) + (7x4)= 21+28=49
OR
7x (5+2)= (7x5) + (7x2)= 35+14=49
Explain what partitive division is AND give an example of a partitive division situation (you don't need to solve your example problem).
A partitive division problem is when we know how many equal groups we need to divide or evenly share the objects, but we don't know how many objects are in each group.
Explain what measurement division is AND give an example of a measurement division situation (you don't need to solve your example problem).
A measurement division problem is when we know how many objects are in each group, but we don't know how many equal groups there are.
