Activity goal: 1. Exercise children's reaction ability and fast running ability. 2. Experience the interest in playing games with your peers. Game method: The number of people in the game should be at least three, and the maximum is not limited. Playing in an area about the size of a badminton court, two people are standing at the two ends of the court, and they are the people who throw sandbags, and they pass each other. The other one can run freely in the field, avoiding the sandbags of two people. If you get hit, you die once. On the contrary, if people in the field receive sandbags once, they can get their lives. (Players can arbitrarily specify the number of lives that players in the venue get when they receive sandbags.) Sandbags can be divided into one hand or two hands, and the number of lives that one hand receives sandbags and two hands receive sandbags is different, which can be specified by players.
