Simultaneous Games vs. Sequential Games
Lesson Summary
This lesson demonstrates the difference between simultaneous and sequential games then concludes with a Kahoot! game.
Clip Summary
In the clip below, players must select a partner and then play a game against each other using marbles. Each pair must decide what type of game is played. Some pairs choose simultaneous games (odds/evens) while others pick sequential games (toss marbles into a hole in the ground). This clip deals with the uncertainty at the start of the game, where the players select partners before they know the rules of the game, and the tension between players when they realize they are competing against their partner  not against other teams.
