## Texas Go Math Grade 4 Lesson 7.3 Answer Key Multiply Using the Distributive Property

Essential Question

How can you use the Distributive Property to multiply a 2-digit number by o I-digit number?
Explanation:
Here, we can use the Distributive property by multiplying a sum by a number is the same as multiplying each addend by the number and adding the products.

Investigate

Materials

• color pencils
• grid paper

You can use the Distributive Property to break apart numbers to make them easier to multiply.

The Distributive Property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products.

A. Outline a rectangle on the grid to model 6 Ã— 13.
Here, we have outlined a rectangle on the grid to the model 6 Ã— 13

B. Think of 13 as 5 + 8. Break apart the model to show 6 Ã— (5 + 8). Label and shade the smaller rectangles. Use two different colors.

Use the Distributive Property. Find the product each smaller rectangle represents. Then find the sum of the products. Record your answers.

_____________ Ã— _____________ = _____________
_____________ Ã— _____________ = _____________
_____________ + _____________ = _____________
6 Ã— 13 = 78.

Explanation:
Here, by using Distributive Property we will break apart 6 Ã— 13 as 6 Ã— (5 + 8),
So 6 Ã— 13 = 6 Ã— (5 + 8)
= (6 Ã— 5)+(6 Ã— 8)
= 30 + 48
= 78.

C. Model 6 Ã— 13 again. Think of 13 as a different sum. Break apart the model to show 6 Ã— ( _____________ + _____________). Find the product each smaller rectangle represents. Then find the sum of the products. Record your answers.

_____________ Ã— _____________ = _____________
_____________ Ã— _____________ = _____________
_____________ + _____________ = _____________
6 Ã— 13 = 78.

Explanation:
Here, by using Distributive Property we will model and break apart 6 Ã— 13 as 6 Ã— (5 + 8),
So 6 Ã— 13 = 6 Ã— (5 + 8)
= (6 Ã— 5)+(6 Ã— 8)
= 30 + 48
= 78.

Make Connections

Another way to model the problem is to use base-ten blocks to show tens and ones.

So, 6 Ã— 13 = 78.

In Step 2, the model is broken into two parts. Each part shows a partial product. The partial products are 60 and 18.
Here, the model is broken into two parts and each part shows a partial product so the partial products are 60 and 18.

Question 1.
5 Ã— 14 = ___________

5 Ã— 14 = 70.

Explanation:
Here, we have used the distributive property for 5 Ã— 14 and modeled the rectangle. So 5 Ã— 14 is
5 Ã— 14 = 5 Ã—(10+4)
= (5 Ã— 10)+(5 Ã— 4)
= 50 + 20
= 70.

Multiply Using The Distributive Property Lesson 7.3 Answer Key Question 2.
4 Ã— 16 = ___________

Explanation:
By using the distributive property for 4 Ã— 16 which is
4 Ã— 16 = 4 Ã— (10+6)
= (4Ã—10) + (4Ã—6)
= 40+24
= 64.

Use grid paper or base-ten blocks to model the product.
Then record the product.

Question 3.
7 Ã— 12 = ___________
7 Ã— 12 = 84.

Explanation:
By using the distributive property for 7 Ã— 12 which is
7 Ã— 12 = 7 Ã— (10+2)
= (7 Ã— 10) + (7 Ã— 2)
= 70+14
= 84.

Question 4.
5 Ã— 16 = ___________
5 Ã— 16 = 80.

Explanation:
By using the distributive property for 5 Ã— 16 which is
5 Ã— 16 = 5 Ã— (10+6)
= (5 Ã— 10) + (5 Ã— 6)
= 50+30
= 80.

Question 5.
9 Ã— 13 = ___________
9 Ã— 13 = 117.

Explanation:
By using the distributive property for 9 Ã— 13 which is
9 Ã— 13 = 9 Ã—(10+3)
= (9 Ã— 10) + (9 Ã— 3)
= 90+27
= 117.

Question 6.

(C) 4 + (10 Ã— 3) = 34
(D) (4 + 10) +(4 + 3) = 21
A.

Explanation:
Given that there are 13 muffins in each box, so the total number of muffins in 4 boxes is (4 Ã— 10) + (4 Ã— 3) = 52.
