Victor makes the table at the right. He uses it to record the types of projects that the third grade classes would like to do for community service.
Make a representation of the data.
Answer:
Graphs are a great way to represent data and numerical information. The visual image that they project help people who need to understand the meaning of the data paint a clearer picture in their mind. There are many different kinds of graphs, but one of the most unique is the type that paints a picture of data using actual pictures. Those types of graphs are known as picture graphs.
Turn and Talk How are your representations alike and how are they different?
Answer:
The representation is the same.
They are different in projects.
The number of pull weeds=15*2=30
The number of Rake leaves=18*2=36
The number of wash cars=12*2=24
the number of clean up=21*2=42.

Question 1.
Mr. Horn counts and records in a table the number of tools he has.
A. How can you tell what a picture graph is about?
Answer: It is about tool supply.
It is already given in the table:
The tools are screwdrivers, wrenches, bolts, nuts.
B. How many should one symbol represent? Choose a number greater than 1.
Think: Half of the symbol stands for half the value of the whole symbol.
Answer:
suppose, Each symbol represents 4 and half of the symbol is 2.
Then the values will be:
The number of screwdrivers=8*4=32
The number of wrenches=12*4=48
The number of bolts=24*4=96
The number of nuts=18*4=72
C. How many symbols will you draw for each tool?
Answer:
The number of symbols drawn for screwdrivers=8
The number of symbols drawn for wrenches=12
The number of symbols drawn for bolts=24
The number of symbols drawn for nuts=18

There are many different kinds of graphs, but one of the most unique is the type that paints a picture of data using actual pictures. Those types of graphs are known as picture graphs.
Turn and Talk What equation can you write to find how many more bolts than nuts Mr. Horn has?
Answer:
The number of bolts=24*4=96
The number of nuts=18*4=72
The number of more bolts than nuts=X
X=number of bolts-number of nuts
X=96-72
X=24
Therefore, 24 more bolts than nuts.

Question 2.
Use the table to record data for the number of each item in your classroom.
Answer:
A picture graph uses symbols and pictures to represent data. Graphs are a great way to represent data and numerical information. The visual image that they project help people who need to understand the meaning of the data paint a clearer picture in their mind. There are many different kinds of graphs, but one of the most unique is the type that paints a picture of data using actual pictures. Those types of graphs are known as picture graphs.
The classroom items data had collected. It means in this solution I had taken own numbers. According to the picture graph we need to answer the below questions.
Question 3.
Use the data in the table to make a picture graph.
A. Write the title. Write the items in the left column. Choose a symbol.
Answer:
The title is classroom items.
The items are bins, closets, desks, posters, shelves.
The symbol might be anything of your choice.
Here I choose the symbol is 
B. Choose a number greater than 1 for what the symbol represents.
Think: Do you need to use half of a symbol?
Answer:
Here we need to choose the number which is greater than 1. So I choose the number 2.
Now the symbol represents 2
And half of the circle is 1
C. Draw the symbols in each row.
Answer:
Graphs are a great way to represent data and numerical information. The visual image that they project help people who need to understand the meaning of the data paint a clearer picture in their mind. There are many different kinds of graphs, but one of the most unique is the type that paints a picture of data using actual pictures. Those types of graphs are known as picture graphs.
D. What equation can you write to find how many fewer closets than desks there are? Solve.
Answer:
The number of closets=4*2=8
The number of desks=6*2=12
The number of fewer closets than desks=X
X=12-8
X=4
Therefore, 4 fewer closets than desks.
Check Understanding
Use the picture graph above.
Question 1.
How would the number of symbols change if the number for your key was half?
Answer:
Each half circle is equal to 1
Now the number of bins is 4*2+2*1=8+2=10
The number of closets is 3*2+2*1=6+2=8
The number of desks is 6*2=12
The number of posters 7*2=14
The number of shelves 5*2=10
On Your Own
Attend to Precision Use the information for 2-5.
The students in Ms. Dover’s class try to solve a math challenge every week. Ms. Dover records the number of students who solve the challenge.
Question 2.
Make a picture graph that shows the data. How will you decide which number to use for your key?
Answer:
Graphs are a great way to represent data and numerical information. The visual image that they project help people who need to understand the meaning of the data paint a clearer picture in their mind. There are many different kinds of graphs, but one of the most unique is the type that paints a picture of data using actual pictures. Those types of graphs are known as picture graphs.
Question 3.
How many more students solved the math challenge in Week 1 than in Week 3?
Answer:
The number of students who solved the math challenge in week 1=15*4=60
The number of students who solved the math challenge in week 3=10*4=40
The number of more students who solved math challenge in week 1 than in week 3=X
X=60-40
X=20
Therefore, 20 more students solved the math challenges in week 1 than in week 3.
Question 4.
How many fewer students solved the math challenge in Week 4 than in Week 2?
Answer:
The number of students who solved the math challenge in week 4=5*4=20
The number of students who solved the math challenge in week 2=25*4=100
The number of fewer students who solved the math challenge in Week 4 than in Week 2=X
X=100-20
X=80
therefore, 80 fewer students solved the math challenge in Week 4 than in Week 2.
Question 5.
Reason Alma will use a symbol of a smiley face to stand for 5 students. How should a row look for Week 2? Explain.
Answer:
Alma uses a symbol of 
.
For 5 students Alma uses a smiley face.
the number of students for week 2=25
I represented each symbol is 4 students.

What do I understand about making a picture graph?
Answer:
– Pictographs represent the frequency of data while using symbols or images that are relevant to data.
– It is a very good idea to make pictographs because it is easy to remember and easier to share with others.
– It is a way to record important information and share it with others.
– Parts of a symbol used does not give exact data in case of large numbers. It can only be used for data given in whole numbers majorly. It is not very useful for larger data that numbers in hundreds or thousands or more. A picture graph is also known as a pictograph or pictogram.
