Main Idea/Vocabulary

4. Of the students in a fifth grade class, 15 play basketball and 18 play soccer. Three of those students play both sports. How many students play only basketball? only soccer?
Example 1

Example 1

6. Plan
One way to solve the problem is to make a Venn diagram. A Venn diagram uses overlapping circles to show how common elements among sets of objects are related. The overlapping section shows the objects that are in both groups.
Example 1

7. Both Basketball and Soccer
Basketball Only
Both Basketball and Soccer
Soccer Only
Solve
Draw two overlapping circles to represent the two different sports. Since 3 students are involved in both sports, place a 3 in the overlapping section. Use subtraction to determine the number for each of the other sections.
15 – 3 = 12 3
18 – 3 = 15
only basketball: 15 – 3 = 12
only soccer: 18 – 3 = 15
Example 1

8. Check
Look back at the problem. Check each circle to make sure that the correct number of students is represented.
