About the lesson
Before this activity is started, some background knowledge must be given on amortization tables. Amortization tables are quite useful when discussing the payback of loans. They are used as ways of calculating the value for business assets over time. This activity will ask students to use their handhelds often. During this activity, students should be familiar with finding and using the finance solver and amortization table.
