Simulations are composed of an introduction or briefing, the simulation itself, and a debriefing that gets at critical thinking and reflection. They provide students with an active role that focuses on and helps bring to life a historical event, character, or concept. The concepts of SUPPLY AND DEMAND are enacted in this simulation through an auction with students as bidders. This simulation has been successfully used in the classroom. It is fairly easy, involves little to no cost, and can be adapted to fit the number of students in your class. This simulation is NOT dependent upon computer technology and has its own specific connections to the Common Core Standards for English Language Arts.
