This document discusses two teaching strategies: 3-2-1 and exit cards. The 3-2-1 strategy has students write down 3 things they learned, 2 questions they still have, and 1 thing they enjoyed after a lesson or reading. This helps the teacher check understanding and gauge interest. Exit cards require students to answer brief questions on paper before leaving class. This provides immediate feedback to teachers on student understanding and questions. Both strategies enhance metacognition and can be modified in various subject-specific ways.
