Guard the Cone is another warm-up adapted from ThePhysicalEducator.com. Good for larger groups of any age and ability.
Players form a large circle. You may find placing spots around the perimeter will help keep the players a safe distance away/keep the circle from shrinking as play commences. Place a cone, perhaps with a ball on top, in the center. One player is designated as Guard. It is his/her job to keep the circle players from hitting the cone. Circle players take turns tossing one ball underhand trying to hit the cone. Note only ONE ball is in play.
If the guard accidentally hits the cone, no harm, no foul.
First player to hit cone becomes the new guard.
