Develop the proverbial “eyes in the back of the head”
One of the most common failings of inexperienced teacher is their tendency to focus on only one child at a time It is pleasant and much “safer” to sit down and read a favorite book with one or two charming children and ignore the chaos going on in the block corner, but good teachers from the habir of total awareness. They develop a sense of what is happening in the entire area. This is true outdoors as well as indoor.
