LESSON 5 Using Picture Graphs

Ana and Frank were thinking about their school as a population. They decided to use their classroom as a sample of the population to collect data about the types of pets their schoolmates have in their homes. After they collected the data, they decided to organize it using a picture graph.

• 

Use Ana and Frank's picture graph to answer the following questions. Be ready to share your answers.

1. This picture graph shows that more students have a dog as a pet than any other animal.
1. If each stick person symbol represents 3 students, how many students have a dog?
2. Show or tell how you know.
2. The picture graph shows that a bird is the pet for the fewest number of students.
1. How many students have a bird for a pet?
2. Show or tell how you know.
3. Use the graph to find out how many students have a cat or a fish for a pet.
4. What is the difference between the number of students who have a dog and the number who have a bird?
5. Ana and Frank collect the same pet data from a different third-grade class in their school. Which pet do you think is most common? Why do you think so?
