Inflation lowers the purchasing power of your money over time.  This means that $100 today will be able to buy less in the future.  This is an important concept to understand so students can make decisions on where to save or invest their money to outpace inflation.  Inflation rates change year to year but over the long term can be modeled using exponential decay.

1. View the MATH Collection: In today’s math activity, students will learn how to calculate percent change! Check it out in MATH: Exponential Decay in Purchasing Power.
2. Example: Students can use this step-by-step example to practice exponential decay problems.

3. Bring in Real World Application: Your students can also review this Visual Capitalist Inflation Infographic that demonstrates a decade of grocery prices for 30 common items.

4. For Your Learning: Join Abby for Virtual PD on Tuesday 5pm PT as she reviews Teaching Remotely: MATH Collection Activities.
