##### Modelling with the natural exponent (e)

## Desmos Dr. Evil

This activity is inspired by Robert Kaplinsky’s task. Learning objectives: exponential growth, inflation, compound interest, and more. By Andrew Stadel.

## Desmos Predicting Movie Ticket Prices

In this activity, students build a model to describe the relationship between average US movie ticket price and time. Students then use that model to make predictions about past and future ticket prices. Students also interpret the parameters of their equation in context.

## Desmos Game, Set, Flat

In this activity, students will develop their understanding of the exponential relationship that describes a bouncing tennis ball. They’ll learn to examine successive terms in a sequence to determine if it represents an exponential relationship or not. They’ll also learn how to construct the exponential equation itself.

## Desmos Rabbits, Rabbits and More Rabbits

The exponential growth of the rabbit population in Australia. I would recommend a pause after slide 1 and class wide notice and wonder looking at the data in the table together. By Paul Jorgens.
