Below are a collection of games that I have used in my lessons. They are simple to implement and can be modified in different ways to suit your needs.
Give your game a purpose, a deeper reason for engaging in the game. Could it be to reinforce the learner profile of being 'principled'? Or a game of Strike and Run could be used in a mini-coach fashion and students could be working on their ATL of 'Recording Data'. Playing the games for fun is fine occasionally, but these games do have the potential for critical learning to occur. It just depends on how you frame your game.
