Show budding mathematicians how to model a diminishing bacteria colony two ways—graphically and algebraically. Using the coordinate axis, pupils create a graph to represent the decay of a bacteria colony. They determine the number of bacteria at certain time frames and when the colony will contain a given size by finding the equation that represents the size of the colony. Finally, scholars discuss the idea of having a fractional number of bacteria and how it relates to the concept.

Instructional Ideas
- Lead a discussion on other exponential equations that would be equivalent
Classroom Considerations
- The class should have an understanding of exponential decay
- Need to sign up for a free CK-12 account before logging in
Pros
- Allows students to view the correct answer if answering incorrectly
- Provides feedback to a mathematically correct answer that does not make sense in the situation
Cons
- Using a bar graph to represent a point in time is confusing
