You could use it in the first lesson of the unit, to help give students an overview.
Or, it would be a great homework activity: students could be tasked with reading the ‘story’ independently, and then answering the comprehension tasks at the end.
Help introduce students to the ‘Middle Ages’, and to the big themes and concepts that will be explored in the unit.
These include religion, travel, trade and life for ordinary medieval people.
Introduce them, too, to the focus on change and continuity that is threaded through the unit, by asking them to identify some of the changes and the continuities that are addressed in the activity itself.
