My Dream Vehicle Gr 6-9 Math Project: Percents, Interest, Decimals
This project was designed with a certain group in mind - disengaged boys.
In this 20 page math project, students choose a vehicle from a newspaper or the local buy/sell/trade paper.
They'll choose what upgrades they'd like to make (new tires, paint job etc.) and then calculate the cost of the vehicle, with taxes, the upgrades- with taxes to figure out how much money they need from the bank.
Students also need to calculate the interest on their bank loan and their monthly payment.
