Students are given information about a regular Toyota Camry and Hybrid Toyota Camry (MPG, price, etc). The students have to figure out how long they have to have the car to make the difference in price worth it.
This is a fun math activity, all in Spanish. We have a class discussion over it one day, they work in groups trying to figure out what information is needed and then they have about a week to come up with a solution. Many students bring this home and share it with their parents. Fun and interesting activity!
