SPENT is a great interactive for Practical Living and Economics classrooms. The site comes through a Faith Based Ministry called Urban Ministries of Durham, so if that is an issue for your school, I wanted to let you know that. However, I hope that it is not an issue because this could be a great lesson for students who don't have a grasp of reality.
Students will go through a process of seeing if they can make $1000 a month last while trying to take care of a kid, daily issues, bills, make a paycheck last, etc. The goal is to finish the interactive with positive money in the account after 30 days. Each selection that a student makes in the interactive, it provides a scenario for making that decision and information about homelessness and poverty. It is a great way for students to gain a "realistic" view of life on a low income.
I highly recommend doing this as a class and letting students choose options as a class and see if as a class they can succeed.
