### Eureka Math Grade 3 Module 1 Lesson 16 Problem Set Answer Key

Question 1.

Label the array. Then, fill in the blanks below to make true number sentences.

Answer:

6 × 4 = 24

Explanation:

Labeled the array and filled the blanks to make true number sentences as (6 × 4) = (5 × 4) + (1 × 4) = 20 + 4 = 24.

6 × 4 we write as ((5 + 1 ) × 4).

So 6 × 4 = 24.

Answer:

7 X 4 = 28,

Explanation:

Labeled the array and filled the blanks to make true number sentences as (7 × 4) = (5 × 4) + (2 × 4) = 20 + 8 = 28.

7 × 4 we write as ((5 + 2) × 4).

So, 7 × 4 = 28.

Answer:

8 × 4 = 32,

Explanation:

Labeled the array and filled the blanks to make true number sentences as (8 × 4) = (5 × 4) + (3 × 4) = 20 + 12 = 32.

8 × 4 we write as ((5 + 3) × 4).

So, 8 × 4 = 32.

Answer:

9 × 4 = 36,

Explanation:

Labeled the array and filled the blanks to make true number sentences as (9 × 4) = (5 × 4) + (4 × 4) = 20 + 16 = 36.

9 × 4 we write as ((5 + 4) × 4).

So, 9 × 4 = 36.

Question 2.

Match the equal expressions.

Answer:

Explanation:

Matched the equal expressions as

(5 × 4) + (3 × 4) = (5 + 3) × 4 = 8 × 4 = 32,

(5 × 4) + (1 × 4) = (5 + 1) × 4 = 6 × 4 = 24,

(5 × 4) + (4 × 4) = (5 + 4) × 4 = 9 × 4 = 36,

(5 × 4) + (2 × 4) = (5 + 2) × 4 = 7 × 4 = 28.

Question 3.

Nolan draws the array below to find the answer to the multiplication expression 10 × 4. He says, “10 × 4 is just double 5 × 4.” Explain Nolan’s strategy.

Answer:

Nolan’s strategy is 10 × 4 = 2 × (5 × 4) = 2 × 20 = 40, or 10 × 4 = 40,

Explanation:

Given Nolan draws the array to find the answer to the multiplication expression 10 × 4.

Nolan says, “10 × 4 is just double 5 × 4.” Nolan’s strategy is 10 × 4 = 2 × (5 × 4) = 2 × 20 = 40 is same as 10 × 4 = 40.

So, “10 × 4 is just double 5 × 4.”

Destiny says, “I can use 5 × 4 to find the answer to 7 × 4.”

Use the array below to explain Destiny’s strategy using words and numbers.

Answer:

Explanation:

Given Destiny says, “I can use 5 × 4 to find the answer to 7 × 4.”

Used the array to explain Destiny’s strategy using words and numbers as to find 7 × 4 we write 7 as (5 + 2) and multiply with 4 as

(5 + 2) × 4 = (5 × 4) + (2 × 4) = 20 + 8 = 28, So we used 5 × 4 to find the answer for 7 × 4.

or 8 × 4 = 32.

Question 2.

Match the multiplication expressions with their answers.

Answer:

Explanation:

Matched the multiplication expressions with their answers as

4 × 6 = 24,

4 × 7 = 28,

4 × 8 = 32,

4 × 9 = 36.

Question 3.

The array below shows one strategy for solving 9 × 4.

Explain the strategy using your own words.

Answer:

Explanation:

Given the array shown one strategy for solving 9 × 4.

The strategy used is 9 × 4 = (5 × 4) + (4 × 4) = 20 + 16 = 36,

9 × 4 = 36.
