A Bryant elementary third grade classroom of boys and girls with their teacher. The children are seated at their desks, the unidentified woman teacher is standing at the rear of the room. Blinds are drawn, but sunlight is peeking in below the one near the teacher. The classroom is full of interesting items, but the drawing of the Aerial Bridge on the large blackboard is delightful. The day's schedule is on the back corner blackboard. Drawing is a twenty-minute slot after lunch and before geography. Jane, Rose, Edith, Grace and Irene are named Busy Workers and have stars by their names on the blackboard.
