and complete the number bond.

Answer:

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 × 4 = (5 × 4) + (1 × 4) = 20 + 4 =24, or 6 × 4 = 24.

### Eureka Math Grade 3 Module 1 Lesson 18 Homework Answer Key

Question 1.

Match.

Answer:

Matched as shown below :

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___

(_5_ × 4) + (_4_ × 4) = 9 × 4

_20__ + _16_ = _36_

9 × 4 = _36_.

Answer:

9 X 4 = 36,

(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,

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,

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.

Question 5.

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

Answer:

There are 70 days in 10 weeks,

Explanation:

Given there are 7 days in 1 week. So number of days in 10 weeks are 7 × 10 = 70 days.

Therefore there are 70 days in 10 weeks.
