This is one of my most popular lesson activities. Students read detailed background knowledge before completing a hexagonal card sort to divide reasons up into belief systems, technology, geography and economics. Here students will make links between their factors to create a visual map which they can use for an extended piece of written analysis. I am especially proud of the level of precision and detail in the historical content here. The eighteen cards are broken down and color coordinated for differentiation purposes. I really hope you enjoy this activity and that your students get as much from it as mine do. Please watch the video for a quick feel of how this task works.
