After teaching my algebra students about exponential functions and exponential growth, I like to give them this exercise so they can see the magic of compound interest in a real-life scenario. This activity includes a scenario in which a person saves $300 every month and invests it at 6% compound interest, and it also looks at investing in the stock market with actual stock prices.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
For this worksheet, I expect students to show their work on a separate sheet of paper.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
