## HMH Into Math Grade 3 Module 18 Lesson 1 Answer Key Use Picture Graphs

I Can use data in a picture graph to solve how many more and how many less problems.

**Spark Your Learning**

Ms, Marin’s students are showing data that they collected. On what topic might the students have collected information?

Use your topic idea to complete the graph.

Answer:

A picture graph is a pictorial display of data with symbols, icons, and pictures to represent different quantities. The symbols, icons, and pictures of a picture graph typically represent concepts or ideas or stand-in for a larger quantity of something.

**Turn and Talk** Discuss your scenario with a partner. Ask your partner questions that can be answered by using the graph.

Answer:

In the above-given question:

Suppose, the giraffes are 2

The rhinos are 4; the elephants are 3

**Build Understanding**

Question 1.

Ami records the number of each type of tree she sees.

Connect to Vocabulary

A picture graph uses symbols to show and compare information. Picture graphs have a key that tells the number of objects each symbol represents.

A. How do you know how many trees each tree symbol stands for in the graph?

Answer:

Each tree symbol stands for 2 trees. It was already given.

Once see the picture graph, all the trees are different.

B. What equation can you write to find the number of willow trees Ami sees? How many willow trees does Ami see?

Answer:

the number of willows trees=X

as we already know each given symbol is 2 trees.

In willows trees, there are 3 tree symbols.

X=3*2

X=6

Therefore, 6 willow trees Ami sees.

C. If stands for 2 trees, what does stand for in the graph? Explain.

Answer:

stands for 2 trees.

And half of two is 1.

stands for 1 tree

D. How can you find the number of palm trees Ami sees?

Answer:

The number of palms trees=X

In palm trees, there are 3 and 1

X=3*2+1*1

X=6+1

X=7

Therefore, 7 number of palm trees Ami sees.

**Turn and Talk** How would the data be displayed for Pine, Maple, and Oak if the tree symbol represented 4 trees?

Answer:

Currently, each represents 2 trees. But in the question represents 4 trees then the pine, maple, and oak trees are:

In the above-given picture graph:

the pine trees=X

X=4*2

X=8

therefore, the pine trees are 8.

Now calculating maple trees:

Maple trees=Y

Y=1*4

Y=4

Therefore, the maple trees is 4.

Now calculate Oak trees:

Oak trees=Z

Z=2*4

Z=8

Thus, the oak trees are 8

Question 2.

Rowan records the types of plants sold at the store on Saturday.

A. What equation can you write to find the number of aloe plants sold? How many aloe plants were sold?

__________ aloe plants

Answer:

Each plant = 4 plants

The number of aloe plants=X

X=5*4

X=20

therefore, 20 plants were sold.

B. What equations can you write to find the number of bamboo plants sold? How many bamboo plants were sold?

___________ bamboo plants

Answer:

the number of bamboos plants=B

B=2*4+1*2

B=8+2

B=10

therefore, 10 plants were sold.

C. How can you find how many more aloe plants than bamboo plants were sold?

Answer:

From the above calculation:

The number of bamboo plants sold=10

the number of aloe plants sold=20

The number of more aloe plants than bamboo plants were sold=X

X=20-10

X=10

Therefore, 10 more aloe plants than bamboo plants were sold.

**Turn and Talk** How did you know which operation to use to compare the amounts?

Answer: It is good to know if one number is the same as, or smaller than, or bigger than, another number

We compare the trees to one another.

Likewise, we compare the amounts.

**Check Understanding**

**Use the picture graph above.**

Question 1.

How many fewer cactus plants than lily plants were sold?

Answer:

The number of lily plants sold=3*4+2*1=12+2=14

The number of cactus plants was sold=2*4=8

The number of fewer cactus plants than lily plants were sold=X

X=14-8

X=6

Therefore, 6 fewer cactus plants than lily plants were sold.

Question 2.

How many more aloe plants than violet plants were sold?

Answer:

the number of aloes plants=5*4=20

The number of violets plants=4*4=16

the number of more aloe plants than violet plants=X

X=20-16

X=4

Therefore, 4 more aloe plants than violet plants were sold.

**On Your Own**

**Reason** Use the graph for 3-7.

Dean surveys his friends about the number of books they read in the summer.

Question 3.

How many books did the 5 friends read?

Answer:

The number of books Cole read=5*3=15

The number of books Patti read=5*2=10

The number of books Katie read=5*2=10

The number of books Andy read=5*1=5

The number of books Lamar read=5*3=15

Now add the total books be X.

X=15+10+10+5+15

X=55

Therefore, the number of books did the 5 friends read are 55.

Question 4.

How many more books did Lamar read than Katie?

Answer:

The number of books Lamar read=5*3=15

The number of books Katie read=5*2=10

The number of more books did Lamar read than Katie=X

X=15-10

X=5

Therefore, 5 more books did Lamar read than Katie.

Question 5.

How many friends read fewer than 10 books?

Answer: 1

The number of books Cole read=5*3=15

The number of books Patti read=5*2=10

The number of books Katie read=5*2=10

The number of books Andy read=5*1=5

The number of books Lamar read=5*3=15

compared to all the numbers there is only a friend who read fewer than 10 books.

Question 6.

How many fewer books did Andy read than Cole?

Answer:

The number of books Andy read=5*1=5

The number of books Cole read=5*3=15

The number of fewer books did Andy read than Cole=X

X=15-5

X=10

Therefore, 10 fewer books Andy read than Cole.

Question 7.

**Open-Ended** Write a question that can be answered using information from the graph.

Answer:

How many fewer books did Lamar and Katie have?

The number of books Lamar read=15

the number of books Katie read=10

The number of fewer books did Lamar and Katie have=X

X=15-10

X=5

Therefore, 5 fewer books Lamar read than Katie.

**I’m in a Learning Mindset!**

How does using multiplication to find the total number in each picture graph category make me feel about my learning?

Answer:

The data is given in the above picture graph.

Each picture is equal to 5 books

So that we need to multiply with the particular friend who reads the particular number of books.

For example, take the above-given picture graph:

The number of books Cole read=5*3=15

The number of books Patti read=5*2=10

The number of books Katie read=5*2=10

The number of books Andy read=5*1=5

The number of books Lamar read=5*3=15

Now add the total books be X.

X=15+10+10+5+15

X=55

Therefore, the number of books did the 5 friends read are 55.

Likewise, we can find the total number in each picture graph.
