This document outlines a lesson plan on illuminated manuscripts during the Middle Ages. Students will first discuss what illuminated manuscripts were and examples of primary sources. They will then be introduced to an activity where they will create their own illuminated journal describing a day in the life of different medieval classes. The lesson concludes with students presenting their favorite journal entry and receiving feedback. Throughout, the teacher will informally assess student understanding through questioning and observation and provide real-time feedback. Formally, student graphic organizers and illuminated journals will be assessed against rubrics.
