McGraw-Hill My Math Grade 3 Answer Key Chapter 12 Lesson 2 Draw Scaled Picture Graphs

In Grade 2, you used a picture graph with different pictures to represent data. A pictograph uses the same symbol to represent more than one. For this reason, it is also called a scaled picture graph.

Math in My World

Example 1

Fifteen students drew pictures of their favorite fruits on sticky notes. Their responses are shown in the picture graph. How can this data be displayed in a pictograph?
McGraw Hill My Math Grade 3 Chapter 12 Lesson 2 Answer Key Draw Scaled Picture Graphs 1
A pictograph displays the same data as a picture graph, but in a different way.

Question 5.
A pictograph shows 2 McGraw Hill My Math Grade 3 Chapter 12 Lesson 2 Answer Key Draw Scaled Picture Graphs 10 symbols. Each symbol represents 3 people who enjoy rock music. How many people enjoy rock music?
McGraw Hill My Math Grade 3 Chapter 12 Lesson 2 Answer Key Draw Scaled Picture Graphs 11
Answer:
A pictograph shows 2 McGraw Hill My Math Grade 3 Chapter 12 Lesson 2 Answer Key Draw Scaled Picture Graphs 10 symbols. Each symbol represents 3 people who enjoy rock music. So, 3+3 =6 people will enjoy rock music.

Question 6.
Answer the questions about the pictograph. What is the most common shoe size?
Answer:
The most common shoe size is size 6.
McGraw Hill My Math Grade 3 Chapter 12 Lesson 2 Answer Key Draw Scaled Picture Graphs 12
How many more students wear a size 4 shoe size than wear a size 8 shoe size?
Number of students who wear size 4 is 4+4+4=12
Number of students who wear size 8 is 4
12-4=8 students wear a size 4 shoe size than size 8 shoe size.

Mathematical PRACTICE Explain to a Friend How many students were asked for their shoe size? Explain.
Answer:
Number of students who wear size 2 is 4
Number of students who wear size 4 is 4+4+4=12
Number of students who wear size 6 is 4+4+4+4+4=20
Number of students who wear size 8 is 4
Thereforee, the total number of students who were asked for their shoe size will be 4+12+20+4=40
