Host Ira Glass introduces a story on the most ambitious and hopeful solution to urban poverty in the country—the Harlem Children's Zone. The project's goal is nothing less than changing the lives of thousands of children in Harlem, starting at birth and continuing until they go to college.

Amy Roberts thought it was obvious that she was an adult, not a kid, and she assumed the friendly man working at the children's museum knew it too. Unfortunately, the man had Amy pegged all wrong.

Host Ira Glass talks with Kayla Hernandez, a seventh-grader who likes to reminisce about when she was a child, back in fifth grade. She visits Room 211 in her school, where her fifth grade class met, and looks at her old books, thinks about what happened there.
