Take a loose group of participants and set them free with a wondrous, cooperative movement journey. They are quickly turned into a "trust me, work with me" team intent on movement and exploration of space. As they move, they not only test their group and individual limitations, they also receive proprioceptive input to their muscles. The Co-Oper Blankets are fabricated from 4-way, 8 ounce, heavy duty Lycra formed into an 8' circle that is either 60" (Full) or 30" (Medium) in height. Co-Oper Blankets include suggested activities, but you and your kids should feel free to invent your own. Small size is ideal for one on one work with therapist.
