Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-14
Explanation:
Given Dylan used the break apart and distribute strategy to
solve a multiplication problem. Looking at his work,
wrote the multiplication problem Dylan solved,
and completed the number bond as shown above,
as 6 X 4 = (5 X 4) + (1 X 4) = 20 + 4 =24, or 6 X 4 = 24.

Question 1.
Match.
Eureka Math 3rd Grade Module 1 Lesson 18 Homework Answer Key 6
Matched as shown below :
Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-15
Explanation:
Matched expressions as
7 tens = 5 tens + 2 tens = (5 X 10) + (2 X 10) = 70,
8 fours = 5 fours + 3 fours = (5 X 4) + (3 X 4) = 32,
9 tens =  6 tens + 3 tens = (6 X 10) + (3 X 10) = 90,
7 threes = 5 threes + 2 threes = (5 X 3) + (2 X 3) = 21.

Question 2.
9 × 4 = ___36___
Eureka Math 3rd Grade Module 1 Lesson 18 Homework Answer Key 7
(_5_ × 4) + (_4_ × 4) = 9 × 4
_20__ + _16_ = _36_
9 × 4 = _36_.

9 X 4 = 36,
Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-16
(5 X 4 + 4 X 4) = 9 X 4,
20 + 16 = 36,
9 X 4 = 36,

Explanation:
Given 9 X 4 =
We can write 9 X 4 as 5 fours + 4 fours,
(5 X 4) + (4 X 4) = 9 X 4,
20 + 16 = 36 or 9 X 4 = 36.

Question 3.
Lydia makes 10 pancakes. She tops each pancake with
4 blueberries. How many blueberries does Lydia use in all?
Use the break apart and distribute strategy, and
draw a number bond to solve.
Lydia uses __40__ blueberries in all.

Lydia uses 40 blueberries in all,
Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-17
Explanation:
Given Lydia makes 10 pancakes. She tops each pancake with
4 blueberries. So number of  blueberries Lydia use in all are
4 X 10 = 40, Used the break apart and distribute strategy as
(2 X 10) + (2 X 10) = 20 + 20 = 40 and drawn a
number bond to solve 4 x 10 as 40.

Question 4.
Steven solves 7 × 3 using the break apart and distribute strategy.
Show an example of what Steven’s work might look like below.

7 X 3 = 21,
Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-18
Example: Steven has 7 friends and each friend has
3 balloons, how many total balloons Steven will collect
from his friends?

Explanation:
Given Steven has 7 friends and each friend has
3 balloons, how many total balloons Steven will collect
from his friends?
Steven solves 7 × 3 using the
break apart and distribute strategy shown above as
7 X 3 = (4 X 3) + (3 X 3) = 12 + 9 = 21,
or 7 X 3 = 21.
So Steven collects 21 balloons in all.

Question 5.
There are 7 days in 1 week. How many days are there in 10 weeks?

There are 70 days in 10 weeks,
