Doubling your money

My friend and I were arguing about how long it would take me to double my investment amounts.  How will your students figure this out?  Are there any tricks?  Explore investing and exponential growth as your students discover "The Rule of 72."  Also check out this Rule of 72 calculator  by Calculatorsoup.com & this video from Khan Academy on the Rule of 72 .

Either while or after students are discovering the rule of 72, consider using this rule of 72 calculator to help cement home the relationship.

For Adventurer members we have an editable Word docx, an Excel data file and solutions.
