Instructional Ideas

• Have students brainstorm other situations that could be modeled by an exponential function
• Assign groups to design their own advertising campaigns

Classroom Considerations

• Assumes a basic understanding of exponents

Pros

• Class members develop their own models before being instructed on what type of mathematical model would work best
• Teacher's guide contains an interesting explanation for why viral epidemics can be problematic to model with exponential functions

Cons

• The idea of focus groups is presented but not explained
