Students are grouped to represent countries that imperialized Africa. They claim territory by posting their country's flag over a blank map of Africa. When 2 groups want the same piece of land, they battle it out using rock-paper-scissors. The winning group is the one who best accomplishes their given objective.
I have created my own version of the game to be used as an introduction to 19th century imperialism. It contains everything you need from the bell ringer and task cards, to exit slip questions.
It doesn't get any simpler than this! the paid version allows you to open the PowerPoint, print out the materials, and project everything else from the bell ringer to the exit slip.
