The WW1 Online Simulation  is an enhancement to HistorySimulation.com's World War One Simulation Lesson Plan which is a hands on, interactive lesson plan that incorparates critical thinking skills and problem solving skills.  This is a one year subscription for access to the Online platform.  You can make as many simulations as you need, but each teacher that uses it needs a license to use it.  You need to purchase or already have the World War One Simulation Lesson Plan.

You need 1 teacher license for every teacher that is going to be using the online simulation.  The number of students or classes involved in the simulation does not matter.  You can use the simulation as many times as you want.
