Blindfold activities impel students into working together more closely, promoting interaction and trust building among the students. For the sake of ELT teaching, this type of activity can be great warm-ups or wrap-ups and come very handy when we have to teach how to give directions. Below, I selected a number of activities for you to have a try.
Blindfolds Robot Wars Procedures: Players work in pairs, a controller who is sighted and a robot who is blindfolded. The robot is in the marked zone and scores points by picking up paper balls and then throwing them at the other robots in the zone. The controller is outside the zone and directing their robot verbally as to where to find the paper balls and then which direction to throw them in. 3 minutes per round works well.
