Section A: Practice Problems Interpret and Represent Data on Scaled Graphs
Section Summary
Details
In this section, we created scaled picture graphs and scaled bar graphs.
We asked and answered questions that could be answered by the graphs.
How many more daisies were seen than violets?
How many fewer students walk home than bike home?
How many more students bike home than walk or ride in a car?
Problem 1 (PreUnit)
The table shows how a group of students most enjoy traveling. Use the table to complete the picture graph.
way to travel 
number of students 

airplane 

hot air balloon 

sail boat 

scooter 
Problem 2 (PreUnit)
Use the bar graph to answer the questions.
How many students recorded their favorite animal?
How many fewer students chose hamsters than dogs?
Problem 3 (PreUnit)
The table shows the favorite summer vacation activity for a group of students.
vacation activities  number of students 

family time  
playing sports  
sleeping in  
reading 
Use the table to complete the bar graph.
Problem 4 (PreUnit)
Find each sum or difference. Show your reasoning.
Problem 5 (PreUnit)
How many objects are in each array? Explain or show your reasoning.
Problem 6 (Lesson 1)
The graph shows some information about flowers in the garden.
Write one fact you know based on the data shown in the graph.
Write 2 questions you could answer about the data in the bar graph.
Problem 7 (Lesson 2)
The bar graph shows the numbers of different types of flowers in the garden. Use the graph to answer the questions.
How many flowers are represented on the graph?
How many tulips, sunflowers, and daffodils were there altogether?
Problem 8 (Lesson 3)
This picture graph records types of balls in the gym. Use the graph to answer the questions.
How many basketballs are in the gym?
How many more basketballs are there than footballs?
Write one other question that you could answer about the balls in the gym using the graph.
Problem 9 (Lesson 4)
The table shows the favorite sports of some students. Use it to complete the scaled picture graph.

square 

hexagon 
Problem 11 (Lesson 6)
The table shows the number of books some students have at home.
Use the information from the table to create a scaled bar graph.
books  number

Problem 12 (Lesson 7)
The graph shows the number of different kinds of nuts in a bowl.
How many more pistachios are there than walnuts? Explain or show your reasoning.
How many fewer pecans are there than peanuts? Explain or show your reasoning.
Problem 13 (Lesson 8)
The scaled bar graph shows how many students are in each class.
How many students are in the 4 classes altogether? Explain or show your reasoning.
How many fewer students are in class 1 than in class 4? Explain or show your reasoning.
Problem 14 (Exploration)
There are 1,000 students at the 4 schools. What is the approximate scale for the bar graph?
Problem 15 (Exploration)
Collect data of interest to you and make a bar graph. You may use the bar graph template if you wish.
