## Desmos Sequences Sort

Students sort cards of arithmetic and geometric sequences that have been represented in multiple ways (visual, explicit, recursive) – by Matt Baker.

## Desmos Avi and Benita's Repair Shop

In this twist on a classic activity, students compare linear and exponential growth in the context of daily payments. One plan increases by $100 each day, while another grows by doubling the previous day’s payment.

## Desmos Studying bacteria

Students use compound percentages/exponential growth/geometric sequences to find the number of bacteria after a certain amount of time, by Becky Hall.
