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.

6 x 4 = 24

Explanation:
Labeled the array and filled the blanks to make true
number sentences as (6 X 4) = (5 X 4) + (1 X 4) =
20 + 4 = 24.  6 X 4 we write as ((5 + 1 ) X 4).
So 6 X 4 = 24.

7 X 4 = 28,

Explanation:
Labeled the array and filled the blanks to make true
number sentences as (7 X 4) = (5 X 4) + (2 X 4) =
20 + 8 = 28. 7 X 4 we write as ((5 + 2) X 4).
So, 7 X 4 = 28.

8 X 4 = 32,

Explanation:
Labeled the array and filled the blanks to make true
number sentences as (8 X 4) = (5 X 4) + (3 X 4) =
20 + 12 = 32. 8 X 4 we write as ((5 + 3) X 4).
So, 8 X 4 = 32.

9 X 4 = 36,

Explanation:
Labeled the array and filled the blanks to make true
number sentences as (9 X 4) = (5 X 4) + (4 X 4) =
20 + 16 = 36. 9 X 4 we write as ((5 + 4) X 4).
So, 9 X 4 = 36.

Question 2.
Match the equal expressions.

Explanation:
Matched the equal expressions as
(5 X 4) + (3 X 4) = (5 + 3) X 4 = 8 X 4 = 32,
(5 X 4) + (1 X 4) = (5 + 1) X 4 = 6 X 4 = 24,
(5 X 4) + (4 X 4) = (5 + 4) X 4 = 9 X 4 = 36,
(5 X 4) + (2 X 4) = (5 + 2) X 4 = 7 X 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.

Nolan’s strategy is 10 X 4 = 2 X (5 X 4) = 2 X 20 = 40,
or 10 X 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 X 4 = 2 X (5 X 4) =
2 X 20 = 40 is same as 10 X 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.

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 X 4 we write 7 as (5 + 2) and multiply with 4 as
(5 + 2) X 4 = (5 X 4) + (2 X 4) = 20 + 8 = 28, So we used 5 X 4 to
find the answer for 7 X 4.

Question 1.
Label the array. Then, fill in the blanks below to make true number sentences.


Explanation:
Labeled the array and filled in the blanks to make true
number sentences as 6 X 4 = (5 X 4) + (1 X 4) = 20 + 4 = 24,
or 6 X 4 = 24.

Explanation:
Labeled the array and filled in the blanks to make true
number sentences as 8 X 4 = (5 X 4) + (3 X 4) = 20 + 12 = 32,
or 8 X 4 = 32.

Question 2.
Match the multiplication expressions with their answers.

Explanation:
Matched the multiplication expressions with their answers as
4 X 6 = 24,
4 X 7 = 28,
4 X 8 = 32,
4 X 9 = 36.

Question 3.
The array below shows one strategy for solving 9 × 4.
Explain the strategy using your own words.

Explanation:
Given the array shown one strategy for solving 9 × 4.
The strategy used is 9 X 4 = (5 X 4) + (4 X 4) = 20 + 16 = 36,
9 X 4 = 36.

Question 1.
Label the tape diagrams and complete the equations. Then,
draw an array to represent the problems.


Explanation:
Labeled the tape diagram and completed the equations,
Drawn an array to represent the problems as
2 X 4 = 8, 4 X 2 = 8.

Explanation:
Labeled the tape diagram and completed the equations,
Drawn an array to represent the problems as
3 X 4 = 12, 4 X 3 = 12.

Explanation:
Labeled the tape diagram and completed the equations,
Drawn an array to represent the problems as
7 X 4 = 28, 4 X 7 = 28.

Question 2.
Draw and label 2 tape diagrams to model why the statement in the box is true.

Statement in the box is true,

Explanation:
Drawn and labeled 2 tape diagrams to model the statement
in the box is true because as  4 X 6 = 24 and 6 X 4 = 24,
both has result value as 24, So the statement is true.
