The document provides information about interpreting data presented in pie graphs. It discusses key pie graph concepts like the whole circle representing 100% and different sections indicating percentages. It provides examples of pie graphs showing ice cream sales and monthly budget allocation. Questions are presented and answered to demonstrate how to interpret the information in a pie graph, such as identifying the largest section or calculating totals and averages.

Establishing purpose :

5. The following pie graph shows the number of each
flavor of ice cream cones that Mr. Torres sold on a
certain day.
Mango, 10
Flavor of Ice Cream Sold
45

Discussing new concepts #1 :

7. From the pie graph, we can see that :
1. 20 cones of strawberry ice cream were sold that
day.
2. 45 is the greatest number from the graph. So ,
Mr. Torres sold the most cones of vanilla ice
cream.
3. 25 is greater than 20. So, Mr. Torres sold more
cones of chocolate ice cream than strawberry
ice cream.
