Interest rates for banks all across the United States are available to the public. This can be used for more practice, contests, etc. Many, many applications are possible. This is a very practical lesson for students. Since most will be buying a car at one time in their lives, this information is very relevant.
Students can search to find a price for the car of their dreams.
You may also like to find prices for cars of earlier years for other applications other than compound interest. Now, once a student has figured his purchase price, financing is needed. Students can find a rate from a bank in their area and use a formula to calculate their monthly payments. This is another very practical project for the students since most will somehow be involved in buying a house or condominium. Over the course of a few days, students can use time to choose their favorite house from the Internet, find finance rates for their mortgage , and create a presentation detailing their house choice, payments, interest charges, etc.
