Engage students in this exploration activity introducing the concept of exponential functions! Students will graph and write an exponential function from data, distinguish between linear and exponential functions, and reason quantitatively in the context of a fun real world problem.
Hook students with a fun scenario: Leonardo DiCaprio finally won the award for Best Actor! What happens when a meme instantly goes viral on Twitter?
I use this activity as a way to have students explore the concept of exponential functions BEFORE I explicitly teach the unit. It requires guidance and I always have students work in small groups. Guide them along the way and listen and respond to the rich conversations happening in your classroom! It is a great way to challenge your students and allow them to discover patterns on their own.
