The document describes a classroom activity where students play a game of rock-paper-scissors to win candy, representing a capitalist system. A few students win most of the candy while most students lose all their candy quickly. This leads to a discussion of Karl Marx's communist theory and how it relates to the unequal outcomes of the game. The teacher then collects and redistributes the candy equally, representing a transition to socialism. The document uses this game to explain key concepts of Marxism such as the class struggle under capitalism and how socialism and communism aim for more economic equality.
