Whether you are at the park, in the backyard or in the playroom, stay with the children at all times! If you are on duty the safety and well being of the children is your job. Children also find it more enjoyable if you are playing with them rather than sitting on the sidelines watching.
If you have a middle-schooler, who is able to walk to and from school, or play outside with friends, you still need to know where he/she is and whether an adult is present. Make plans for when he/she will call you, where you can find him/her, and what time you expect him/her home.
