There's a simple exercise I've used called "obstacles." I ask for two volunteers. One child is blindfolded and the other is not. The one with the blindfold stands at a starting place in the room. Once the blindfold is on, desks, chairs, etc are arranged to create obstacles. The other student stands on a sturdy box (or other safe structure) so they can see clearly. They proceed to give verbal directions to help their classmate maneuver safely to the finish line. It's a fun activity for all learning styles and you can followup with lots of questions to check for understanding. Students can then practice following directions as they put the room back in order.
