Agenda
- Number talk: True or False — growth and decay claims
- Random groups — a leaking tire, a cooling coffee, a spreading rumour: which of these multiply?
- Consolidate: half-life and doubling time — decay is growth in a mirror
- Launch: Double or Nothing — read the criteria together
- Check your understanding: Exponential Models Practice
Things to do before our next class
- Read Double or Nothing and shortlist two phenomena you could actually measure.
