Children stand close together in a small circle and pass or throw a beanbag or large ball around the circle. They have to imagine the object is a 'hot potato' and to pass/throw it to the next person as quickly as they can
There are many variations to make this game easier or harder. They could start by rolling a ball to each other, then progress to passing it and then to throwing a beanbag or beach ball. Challenge them further by starting with a larger ball and then moving on to smaller balls.
