How does the distributive property help us?
It helps us solve large equations by breaking them into smaller known equations.
(5x7)+(1x7)
or
(3x7)+(1x7)
or
(2x7)+(4x7)

Write the equations if you break apart the columns of 7x8 using 4's facts.
7x4 and 7x4
Show the ways you can break apart 3x7 if you split the rows:
(__x7)+(__x7)
If you split the columns:
(3x__)+(3x__)
if you split the rows:
(1x7)+(2x7)
If you split the columns:
(3x3)+(3x4) or
(3x5)+(3x2)
Draw an array for 7x8 and then break it into two smaller arrays and write the equations for the smaller arrays.
Answers can be:
1x8 and 6x8
3x8 and 4x8
What is the product of 4x6=
4X6=24
Draw an array for 4x8 and show how to break it up using 2's facts.
(2x8)+(2x8)
x x x x x x x x x
x x x x x x x x x
x x x x x x x x x

If chase adds one more row of 8 counters to his array, can he use the (2x8)+(2x8) to solve for the total.
No, because he would have to use (2x8)+(3x8).
Jerome bought 2 adult tickets for $6 each and 7 student tickets for $4 each to go to a play. How much money did he spend in all?
Draw bar diagrams to represent the problem.
(2x6)= 12
(7x4)= 28
12+28=$40

Alma has 6 bags of beads. There are 8 beads in each bag. How many beads does Alma have?
Use the distributive property to solve.
48 beads
What is the product of 6x4=
6x4=24
Explain the distributive property.
Use words- Tell me step by step
The distributive property says that you can take a larger multiplication fact and breaking it up part into easier facts to solve for the product.
Step 1
ex. 8x7= (4x7)+(4x7)
A book store uses 6 books in each display. There are 2 displays on each of the books stores 4 walls. How many books are used in the display?
Draw bar diagrams to represent the problems.
2x6=12
4x12=48 books
What is the name of the property when one is a factor?
Explain the property
Identity property
Anytime one is factor in a multiplication equation the product is the same as the other factor.
