Finding Theme and Proving It With the Text

This unit works with one short passage, "The Stone Bridge": Mira had swept the mason's yard for two years before her uncle let her near the stones. Now she crouched at the river's edge, turning a gray block over in her hands while the other apprentices waited on the bank, arms crossed, certain she would choose wrong. "The center stone has to hold the whole arch," her uncle had told her that morning. "Choose with your eyes, not your hope." She set the block down. It rocked, just slightly, on the uneven ground. Wrong. She picked up a second stone, flatter and heavier, and did not smile until it settled without a wobble. Behind her, someone laughed -- not unkindly, but not kindly either. Mira did not turn around. She had learned that a bridge does not care who is watching, only whether the stones are true.

A theme is not the plot -- what happens -- but the deeper idea about life the story explores, usually stated as a full sentence rather than a single word like "courage." To find one, notice a key choice or realization a character makes, ask what larger idea that choice points to, then test the theme sentence against the WHOLE passage, not just one line, to make sure it truly fits.
