In this lesson, students analyze primary sources in an effort to answer the central historical question: Were political bosses corrupt? The teacher begins by explaining progressives’ complaints about political machines and graft and then shows a political cartoon criticizing Tammany Hall. Students then read and analyze 2 documents: 1) a book excerpt by muckraker Lincoln Steffens, and 2) a ‘talk’ by political boss George Plunkitt. For each, they answer guiding questions on a graphic organizer (the teacher models this extensively with the first document in the lesson). For HW, students write a dialogue between the 2 writers in which Steffens tries to convince Plunkitt to practice honest government.
