Texas Go Math Grade 4 Lesson 9.5 Answer Key Division and the Distributive Property
Essential Question
How can you use the Distributive Property to find quotients?
Answer:
The Distributive Property of division says that dividing a sum by number is the same as dividing each addend by the number and then adding the quotients.
We can use distributive property to find quotients by breaking the Dividend into two addends which can be quotients.
Explanation:
For Example;
Outline a rectangle on a grid to model 69 ÷ 3.
Shade columns of 3 until you have 69 squares.
Investigate
Materials
- color pencils
- grid paper
You can use the Distributive Property to break apart numbers to make them easier to divide.

You can also model 68 ÷ 4 using base-ten blocks.
STEP 1 Model 68.
68 = ________ + ________
Answer:
68 = 40 + 28
Explanation:
Base ten is a counting system that uses ten digits to write down all numbers.
If we want to write any number, we have ten digits we can use: 0 1 2 3 4 5 6 7 8 9.
If you notice, there is no one digit for the number ten- we need to use two digits, the 1 and the 0.
We can only count to nine without the need for two digits.
Therefore, we use base ten in order to make bigger numbers.
STEP 2 Divide the longs into 4 equal groups. 4 longs divide into 4 equal groups with 2 longs left. Regroup 2 longs as 20 small cubes. Divide them evenly among the 4 groups.
60 ÷ 4 = ________
Answer: 15
Explanation:
Divide the longs into 4 equal groups.
4 longs divide into 4 equal groups with 2 longs left.
Regroup 2 longs as 20 small cubes.
Divide them evenly among the 4 groups.
We get, 15.
STEP 3 Divide the 8 small cubes into the 4 equal groups.
8 ÷ 4 = __________
So, 68 ÷ 4 = (60 ÷ 4) + (8 ÷ 4) = _________ + _________ = _________
Answer:
So, 68 ÷ 4 = (60 ÷ 4) + (8 ÷ 4) = 15 + 2 = 17
Explanation:
Divide the longs into 4 equal groups.
4 longs divide into 4 equal groups with 7 left in each group.
Divide the 8 small cubes into the 4 equal groups.
