You are responsible for your own toothpicks, i.e. don’t mix your toothpicks with those of others. Objective: To determine the total number of toothpicks in your group. Before the game begins, your group has 5 minutes to discuss and agree on a strategy so that when all individual members’ toothpicks are put side-by-side, you can very quickly determine the total number of toothpicks by looking and rearranging the toothpicks, without having to perform any arithmetic computations. (Hint: Arrange your toothpicks so that others can visually see how many toothpicks you have.)
