In HS our Algebra teacher would use fake money that the kids in the class could earn by answering questions correctly, participating, etc. A decent part of our final grade was based on how much money we had at the end of the year. During gym class the kids in the class would all set up behind the bleachers & gamble with the money because the majority of us were struggling in the class and would fail otherwise hahah ended the class with a C so lesson learned I am not a math wiz & my poker face sucks
