Disease Spreading

I launched the concept of exponential growth by coming to class dressed like:

I created a sheet titled, "Illness"  with different scenarios. 

• I spread the disease to one person then we each spread it to one person and it continued to spread from there. 
• I spread the disease to two other people and we each spread it to two other people. 

I definitely made an impression on my students.
