Billions and Billions, Retired

How has the human population changed over time? Students build an exponential model for population growth, and use it to make predictions about the future of our planet. Note: This lesson will be removed at 5PM CT Thursday May 10. An updated version will remain available.

Topic: Building Functions (BF), Interpreting Functions (IF), Linear, Quadratic, and Exponential Models (LE)

Green Acres

How has the urban population changed over time, and will we all eventually live in cities? Students use recursive rules along with linear and exponential models to explore how America's urban areas have been growing over the last 200 years.

iPod dPreciation

How has the iPod depreciated over time? Students compare linear and exponential decay, as well as explore how various products have depreciated and what might account for those differences.

I Remember

How much can you trust your memory? Students construct and compare linear and exponential models to explore how much a memory degrades each time it's remembered.
