Before the Activity

Review, as necessary simple interest and compound interest and ensure students read directions and hand out carefully.

During the Activity

Hand out a copy of the That's Interesting sheet to the students to complete. Answers are provided on the Teacher's Notes attachment.

Have students contribute in Activity Centre and discuss any discrepancies of the graphs and possible mathematical reasons why. (i.e., did they forget to change percent to a decimal in the Interest formula, etc.)
