50 + 50 = 100 or 10 × 10 = 100.

Question 5.
There are 7 teams in the soccer tournament. Ten children play on each team. How many children are playing in the tournament? Use the break apart and
distribute strategy, and draw a number bond to solve. There are ____70______ children playing in the tournament.

Answer:
There are 70 children playing in the tournament,
7 X 10 =
Eureka Math Grade 3 Module 1 Lesson 18 Answer Key-13
5 tens + 2 tens = 7 tens
(5 × 10) + (2 × 10) = 7 × 10
50 + 20 = 70
7 × 10 = 70

Explanation:
Given there are 7 teams in the soccer tournament.
Ten children play on each team. So number of children playing in the tournament are 7 × 10 = 70,
Used the break apart and distribute strategy, drawn a number bond to solve 7 × 10 =
wrote 7 as 5 tens + 2 tens = 7 tens,
(5 × 10) + (2 × 10) = 7 × 10,
50 + 20 = 70,
7 × 10 = 70,
Therefore, there are 70 children playing in the tournament.

Question 6.
What is the total number of sides on 8 triangles?

Answer:
Total number of 24 sides on 8 triangles,

Explanation:
Given to find the total number of sides on 8 triangles, as we know a triangle has 3 sides so 8 triangles means

Question 1.
Match.
Eureka Math 3rd Grade Module 1 Lesson 18 Homework Answer Key 6

Answer:
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 × 10) + (2 × 10) = 70,
8 fours = 5 fours + 3 fours = (5 × 4) + (3 × 4) = 32,
9 tens =  6 tens + 3 tens = (6 × 10) + (3 × 10) = 90,
7 threes = 5 threes + 2 threes = (5 × 3) + (2 × 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_.

Answer:

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 × 4 =
We can write 9 × 4 as 5 fours + 4 fours,
(5 × 4) + (4 × 4) = 9 × 4,
20 + 16 = 36 or 9 × 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.

Answer:
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 × 10 = 40, Used the break apart and distribute strategy as (2 × 10) + (2 × 10) = 20 + 20 = 40 and drawn a number bond to solve 4 × 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 × 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 × 3 = (4 × 3) + (3 × 3) = 12 + 9 = 21,
or 7 × 3 = 21.
So Steven collects 21 balloons in all.
