A Conversation Board Game - This conversation board game is easy to create, but one of the most useful ones I have in my magic bag of teacher supplies. If the ones in the photos here look a bit beaten up, it’s because I’ve been using them since 1992! I have also made color photocopies of the boards and had the copies laminated, so that I can roll them up and travel with them when necessary
Team Building Task-The Cup Challenge - take a rubber band and tie 6 strings to it (though I think 5 would work if you want smaller groups). Participants must use only the strings to move 6 cups into a pyramid formation. You can make this a competition between the groups or give them harder cup moving tasks.
