This is a great project that can be used for 4 days or more. Students get a taste of real life where they have to get a job, pay rent, buy groceries, pay for activities, receive unexpected, and pay an income tax. Students not only learn some real life lessons but they also are working with positive and negative numbers, and percentages. This is a fun and educational project and that students can really get into.
I hope you enjoy this activity and let me know what your students think and how I can improve!
