Cumulative Progress Indicator: 2 - The student will explore counting problems involving Venn diagrams with three attributes (e.g., there are 15, 20, and 25 students respectively in the chess club, the debating team, and the engineering society; how many different students belong to the three clubs if there are 6 students in chess and debating, 7 students in chess and engineering, 8 students in debating and engineering, and 2 students in all three?).

Sample Activities:

 

·        Students use Venn diagrams to sort and then report on their findings in a survey. For example, they can seek responses to the question, When I grow up I want to be a) rich and famous, b) a parent, c) in a profession I love, where respondents can choose more than one option. The results can be sorted into a Venn diagram like that at the right, where entries "m" and "f" are used for male and female students. The class can then determine answers to questions like Are males or females in our class more likely to have a single focus? Tabletop, Jr. software can be used to sort and explore data using Venn diagrams.
