If your seniors start putting away $15 per week in September, by prom, they will have ~$500!
Expose your students to budgeting by leveraging their interest in a real-life goal. And what better way to get them excited than with prom?!
If you can empower them to create a budget now, imagine how much more financially responsible they will be when they are ready to move out on their own, buy their first car, save for retirement, etc.
