Representing Data with a Scaled Picture Graph
Representing Data with a Scaled Picture Graph is a Grade 3 math skill from Eureka Math covering how to create and read picture graphs where each symbol represents more than one unit. To find how many symbols a category needs, divide the category's total value by the key value: Number of Symbols = Total Value ÷ Value of Key. For example, if the key says 1 picture = 5, and a category has 20 items, draw 20 ÷ 5 = 4 symbols. Third graders practice both reading scaled picture graphs and constructing them from data sets.
Key Concepts
To determine the number of symbols needed for a category in a picture graph, divide the total value of the category by the value of the key. $$ \text{Number of Symbols} = \frac{\text{Total Value}}{\text{Value of Key}} $$.
Common Questions
What is a scaled picture graph?
A scaled picture graph uses symbols where each symbol represents more than 1 unit. The key defines how many items each symbol stands for.
How do you find how many symbols to draw for a category in a picture graph?
Divide the category's total value by the key value: Number of Symbols = Total Value ÷ Value of Key.
If the key shows 1 symbol = 3 and a category has 15 items, how many symbols are drawn?
15 ÷ 3 = 5 symbols.
How do you read the value of a category from a scaled picture graph?
Count the symbols in that category and multiply by the key value: Total = Number of Symbols × Key Value.
In which textbook is Representing Data with a Scaled Picture Graph taught?
This skill is taught in Eureka Math, Grade 3.
