Growth and Decay Scenarios: Matching Practice for Grade 8
A matching-style practice set of about one page that pairs real-world growth and decay situations, like population change and compound interest, with the exponential equations that model them. It builds skills in identifying starting amounts, rates, and time variables and choosing the correct form of the equation, and it includes a formula reference box to support students who need it.

Teacher Guide & Tips
- Use this as a warm-up or small-group station after a brief mini-lesson on exponential growth and decay, usually about 20 to 25 minutes.
- Discussion question: In the population scenario, why does the equation use (1 + 0.05) instead of 0.05, and what would change if the town were shrinking instead?
- Scaffold for struggling readers: Have students first underline the starting amount, the percent rate, and the time variable in each scenario, then convert the percent to a decimal before matching.
- Extension for advanced students: Ask them to write a new scenario involving decay (such as a car losing value) and create its equation, then explain how they chose the sign.
- Estimated time: Roughly 20 to 25 minutes for completion, plus 5 minutes for whole-class review of the answer pairings.
