Set up this sponge activity by making a path using string, tape, or meter/yard sticks. You will want this path to have turns at angles that your students are familiar with (typically 30, 45, 60, 90, 120, 180). One student will be blindfolded and the rest of the class must lead them along the path by telling them how to move. For example, "take two steps forward, turn 45 degrees to the right, and take one large step."
