Eureka Math Grade 4 Module 3 Lesson 19 Problem Set Answer Key

Question 1.
When you divide 94 by 3, there is a remainder of 1.
Model this problem with place value disks. In the place
value disk model, how did you show the remainder?
Answer:

I showed my remainder by circling the remaining one
in the ones place.

Explanation:
When we divide 94 by 3, there is a remainder of 1.
Modeled the problem with place value disks. In the place
value disk model, showed the remainder by circling the
remaining one in the ones place.

Question 2.
Cayman says that 94 ÷ 3 is 30 with a remainder of 4.
He reasons this is correct because (3 × 30) + 4 = 94.
What mistake has Cayman made? Explain how he can
correct his work.
Answer:
Cayman mistake is that his remainder is greater than
his divisor means he can divide more.
Instead of 30 groups he can make 31 groups.

Explanation:
Given Cayman says that 94 ÷ 3 is 30 with a remainder of 4.
He reasons this is correct because (3 × 30) + 4 = 94.

into10 ones column as shown above.

Question 4.
Two friends evenly share 56 dollars.
a. They have 5 ten-dollar bills and 6 one-dollar bills.
Draw a picture to show how the bills will be shared.
Will they have to make change at any stage?
Answer:
Yes, they will have to make change for 1 dollar bill.

Explanation:
In order to share its the ten dollar bill needs to be decomposed
into one dollar bills.
Drawn a picture to show how the bills will be shared
and have to make changes as shown above.

b. Explain how they share the money evenly.
Answer:
Each friend gets 2 ten dollar bills and 8 one dollar bills,

Explanation:
Given two friends evenly share 56 dollars,
they have 5 ten-dollar bills and 6 one-dollar bills,
they shared the money evenly as 2 ten dollar bills and
8 one dollar bills.

Question 5.
Imagine you are filming a video explaining the
blem 45 ÷ 3 to new fourth graders. Create a script to
explain how you can keep dividing after getting a
remainder of 1 ten in the first step.
Answer:

Explanation:
Watch as I solve 45 ÷ 3 using a place value chart.
First I divide my tens, Each of the 3 groups can equally
have 1 ten. There is 1 ten remaining, We can continue
dividing by decomposing the 1 ten into 10 ones. Watch as
I show this on my chart. Now I have 15 ones that can be
equally distributed into our 3 groups. Each group will get
5 ones. Now we can see that 45 ÷ 3 is 1 ten 5 ones or 15.

Question 1.
Molly’s photo album has a total of 97 pictures.
Each page of the album holds 6 pictures.
How many pages can Molly fill? Will there be any
pictures left? If so, how many? Use place value disks to solve.
Answer:
Molly can fill 16 pages,
Yes, there will be 1 picture left,

Explanation:
Given Molly’s photo album has a total of 97 pictures.
Each page of the album holds 6 pictures, So number of
pages can Molly fill are 97 ÷ 6 = 16 quotient and 1 remainder
means Molly can fill 16 pages and there will be 1 picture left
as shown above using place value disks.

Question 2.
Marti’s photo album has a total of 45 pictures.
Each page holds 4 pictures. She said she can only
fill 10 pages completely. Do you agree? Explain why or why not.
Answer:
No, I don’t agree, why because she can fill 11 pages completly
with 1 picture left,

Explanation:
Marti’s photo album has a total of 45 pictures.
Each page holds 4 pictures. She said she can only
fill 10 pages completely, I don’t agree because
if we divide 45 pictures by 4 we get 11 pages but she
said she can only fill 10 pages completely so disagree.

Question 1.
When you divide 86 by 4, there is a remainder of 2.
Model this problem with place value disks. In the
place value disk model, how can you see that there is a remainder?
Answer:
I showed my remainder by circling the remaining two
in the ones place,

Explanation:
When we divide 86 by 4, there is a remainder of 2.
Modeled the problem with place value disks. In the place
value disk model, showed the remainder by circling the
remaining two in the ones place.

Question 2.
Francine says that 86 ÷ 4 is 20 with a remainder of 6.
She reasons this is correct because (4 × 20) + 6 = 86.
What mistake has Francine made? Explain how she can
correct her work.
Answer:
Francine mistake is that her remainder is greater than
his divisor means he can divide more.
Instead of 20 groups he can make 21 groups,

Explanation:
Given Francine says that 86 ÷ 4 is 20 with a remainder of 6.
Her reasons this is correct because (4 X 20) + 6 = 86.
Instead of 20 groups he can make 21 groups,
86 ÷ 4 when 86 is divided by 4
we get 21 as quotient and remainder is 2.

Question 3.
The place value disk model is showing 67 ÷ 4.
Complete the model. Explain what happens to
the 2 tens that are remaining in the tens column.

Answer:
The 2 tens remaining gets decomposed into
20 ones column,

Explanation:
Given the place value disk model is showing 67 ÷ 4.
Completed the model. Explained what happens to the
2 tens that is remaining in the tens column gets decomposed
into 20 ones column as shown above.

Question 4.
Two friends share 76 blueberries.
a. To count the blueberries, they put them into small
bowls of 10 blueberries. Draw a picture to show how the
blueberries can be shared equally. Will they have to split
apart any of the bowls of 10 blueberries when they share them?
Answer:
Yes, they will have to make change for 1 bowl,

Explanation:
In order to share it the 10 blueberries needs to be decomposed
into ones blueberries.
Drawn a picture to show how the blueberries will be shared
and have to make changes as shown above.

b. Explain how the friends can share the blueberries fairly.
Answer:
Each friend gets 3 ten blueberries and 8 blueberries,

Explanation:
Given two friends can share 76 blueberries,
they have 3 ten-blueberries and 8 one-blueberries,
Each friend shared 3 ten blueberries and 8 blueberries.

Question 5.
Imagine you are drawing a comic strip showing how to
solve the problem 72 ÷ 4 to new fourth graders. Create a
script to explain how you can keep dividing after getting a
remainder of 3 tens in the first step.
Answer:

Explanation:
Created a script as I solve 72 ÷ 4 using a place value chart.
First I divide my tens into 4 groups I get 4 tens into 1 group,
There are 3 tens remaining, We can continue
dividing by decomposing the tens into 30 ones. Watch as
I show this on my chart. Now I have 32 ones that can be
equally distributed into our 4 groups. Each group will get
8 ones. Now we can see that 72 ÷ 4 is 1 ten 8 ones or 18.
