Try to think of things that were important to Scout or perhaps symbolize important events in her life. For instance, you might put a newspaper in Scout's box because Atticus
taught her to read the paper with him each night. This led to an interesting confrontation at school with Scout's teacher. You may want to think of an item to represent important people to Scout. Calpurnia, Dill, Jem
, and Boo Radley were important in Scout's coming of age. You may want to include some of the things Scout found in the tree with Jem on the way to school. Perhaps the blanket that Boo Radley covered Scout's shoulders with would be important to her. Both the gifts in the tree and the blanket helped Scout to realize that people aren't always judged accurately.
