Day 104: Thinking About the Future

Students are introduced to the scenario: You have just graduated from college and managed to land a job (hopefully using the degree you just earned.)  You are ready to buy your first dream house or condo.  I have the students use the randint( function on their Nspires to determine the range of house values they qualify for.  Then they define some terms such as FICO score, points, and ARM.  Then they use the internet to search for a home that fits their range.  20150212_12081820150212_120912
