During the month of July, I worked four days a week at the Hunter school, teaching kids aged eight to nine years old. They had three classes each day, including science, writing, and art. As a student aide, my job was to guide students through what they were learning, encourage them, and supervise them, all while maintaining a positive, yet stern atmosphere that prevents the kids from messing around all day (which is by any means, not very easy).
Although I had gained some experience teaching younger kids the previous year, working with young and energetic students can be very difficult regardless of age. The kids I worked with were very sweet, however, and I very much enjoyed working and playing with them.
P.S. Beware of tag! It can be more dangerous than you think!
