John Murray demonstrates The Spin Game. Here is a great activity to help your child with visual tracking, body awareness and helping them calm down before doing reading activities, or any time you will be asking your child to remain relatively still for a period of time. This can be done before sitting still for meals or doing school work. A good way to break up school activities, end a unit or subject, stretch then add the spin game before heading into the next activity.
As John explains it creates a situation where the eyes my move separately from the head, which is done in reading and other visual tracking activities, like in many sports.
