  3. I will solve problems by using logical reasoning. 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

  5. Understand What facts do you know? • 15 students play basketball. • 18 students play soccer. • 3 of those students play both sports. What do you need to find? • The number of students that play only basketball and only soccer. Example 1

  6. 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. Plan Example 1

  7. 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. 18 – 3 = 15 3 15 – 3 = 12 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. Example 1
