Set up an area with randomly placed cones throughout. Each cone represents a mine which must be avoided. The students pair up and one has a blindfold on. The student without the blind fold on has to direct, using their voice, the other student through the minefield. Once they make it to the other side, the students swap over roles. No touching or physical direction is allowed, only voice instructions are permitted.
Instead of walking alongside their partner, the student must stand across the other side of the minefield and give their instructions from there. Have groups of three with two people blindfolded. Have groups of three with one person blindfolded.
Change the obstacles so that they are less likely to trip. Place out more spots and softer toys and less big cones.
