Algebra II Module 3, Topic E, Overview

Students in a Group

Topic E is a culminating series of lessons driven by MP.4, Modeling with Mathematics.  Students apply what they have learned about mathematical models and exponential growth to financial literacy while developing and practicing the formula for the sum of a finite geometric series (A-SSE.4).  Throughout this set of lessons, students study the mathematics behind car loans, credit card payments, savings plans and mortgages, developing the needed formulas from summing a finite geometric series in each case.  Key features of tables and graphs are used to answer questions about finances (F-IF.7e).
