Ms. Jacobs’ preschool class begins the day at morning circle. Each child sits on a small rug, including John, who is helped out of his wheelchair to be among his friends. Each child is given a turn to say or sign hello. Those who want to may join in the singing of the morning song. Xiao-lei joins in by turning on her audio recorder. When Ms. Jacobs sees that Deshan needs to move about, she hands him a tambourine so that he can play along to the singing.
