Hexagonal Thinking

Hexagonal thinking as a classroom methodology was popularized in the UK in the late 2000s and early 2010s, though its intellectual roots connect to general systems theory and the concept mapping work of David Ausubel in the 1960s. The hexagonal shape is not merely aesthetic. Unlike rectangular cards or Post-it notes, hexagons share edges on six sides, creating a visual structure that implies relationship and connection in every direction. When you place two hexagons adjacent, you are already claiming that the concepts they represent connect: the placement is a claim that requires justification.

The methodology sits at a productive intersection between visual thinking and analytical reasoning. Students who struggle with linear, text-heavy analysis sometimes find that working spatially with hexagons accesses modes of understanding that traditional academic formats don't reach. Conversely, students who are confident verbal reasoners benefit from having to translate their thinking into a visual arrangement: the translation often reveals assumptions and gaps that articulate reasoning conceals.

The power of hexagonal thinking is in the links, not the placement. Two groups given the same set of hexagons will often produce very different arrangements, and the differences are the most pedagogically productive part of the activity. Why did Group A place 'industrialization' adjacent to 'urbanization' but Group B placed it adjacent to 'labor movements'? What concept is Group A foregrounding that Group B isn't? These differences reveal different mental models of the topic, and making those different models visible to each other is where genuine conceptual development happens.

The verbal annotation of links, requiring students to write or say the nature of each connection rather than just placing hexagons adjacent, is what makes hexagonal thinking an analytical practice rather than a sorting activity. The difference between "these two things are related" and "industrialization caused urbanization because increased factory wages drew rural workers to cities" is the difference between recognition and understanding. The annotation requirement keeps hexagonal thinking in the latter territory.

Cross-link development, connections between branches of the map that aren't hierarchically related, is the most intellectually demanding part of the activity. A student who builds a neat hierarchical tree from a central concept has demonstrated organized knowledge. A student who identifies that a concept at the 'economic causes' branch also connects to a concept at the 'social effects' branch, and can articulate why, has demonstrated a more sophisticated understanding of the topic as a system rather than a set of separate domains.

Hexagonal thinking works particularly well as a pre-assessment, a mid-unit consolidation activity, and an end-of-unit synthesis. As a pre-assessment, it reveals prior knowledge structure before instruction. As a mid-unit activity, it shows how new learning is integrating with existing frameworks. As an end-of-unit activity, it demonstrates the conceptual architecture students have built. Running all three versions of the same hexagonal map across a unit and comparing them tells a powerful story of learning.
